30 Lavender Varieties for Every Purpose: Hardiest for Hedges, Longest-Blooming for Pots

There are more than 450 named lavender cultivars spread across 47 species — and choosing the wrong one is the most common reason lavender fails in American gardens. A gardener in Zone 6 Ohio planting French lavender (Lavandula stoechas) will watch it die back hard every winter. A Zone 9 California gardener growing only English lavender may find it sulks in heat and suffers in summer. The type you choose matters as much as where you plant it.

The good news: there is a lavender for every US garden. English lavenders (L. angustifolia) are the hardiest, surviving Zone 5 winters with ease. Lavandin hybrids (L. × intermedia) grow larger, bloom later and are the source of most commercial essential oil. French and Spanish types (L. stoechas) thrive in the warm South and West, flowering from spring well into summer. And a handful of species lavenders add texture, year-round colour and architectural interest for Zone 8 and above.

This guide covers all 30, organised by type, with USDA hardiness zones, height, fragrance rating and best uses for each. A complete lavender growing guide covers soil, pruning and propagation in depth — this article focuses squarely on helping you pick the right variety for your situation.

English Lavender (Lavandula angustifolia) — Zones 5–8

Lavandula angustifolia is the hardiest lavender, the sweetest-scented, and the only type suitable for cooking. Its essential oil is dominated by linalool with less than 1% camphor — this low camphor content is why it smells clean and sweet rather than medicinal, and why it works in shortbread where lavandin would taste harsh [1]. NC State Extension rates all angustifolia cultivars for Zones 5a–9b with full sun and perfectly drained soil [1].

1. Hidcote

Height: 18–20 in | Zones: 5–8 | Colour: Deep violet-purple | Scent: 4/5 | Best for: Formal borders, low hedges, containers

The benchmark English lavender. Hidcote produces the darkest, most saturated purple of any angustifolia — tighter, more compact flower spikes than Munstead, giving it a crisp, formal look that suits edging and knot gardens. It typically blooms a week or two after Munstead, from late June into July. Gertrude Jekyll herself didn’t use this one (she favoured Munstead, which she developed), but Hidcote became the RHS standard for a reason: consistency. In my experience, it’s also one of the most reliable performers in alkaline, free-draining soil without supplemental irrigation once established.

2. Munstead

Height: 18–24 in | Zones: 5–8 | Colour: Soft lavender-blue | Scent: 3/5 | Best for: Cottage borders, earlier bloom, cut flowers

Developed by Gertrude Jekyll at her Munstead Wood garden, this is the early-season English lavender. It opens a week before Hidcote, with looser, more casual flower spikes in a softer lavender-blue — less formal, more cottagecore. It handles heat marginally better than Hidcote during summer spikes. The US Lavender Growers Association lists it as one of the two most widely grown cultivars in the US for both landscape and small-scale production [7].

3. Royal Velvet

Height: 24–30 in | Zones: 5–8 | Colour: Dark navy-purple | Scent: 5/5 | Best for: Cut flowers, drying, craft

Royal Velvet has the richest, deepest colour of any English lavender — dark navy-blue calyxes with violet corollas that hold their colour exceptionally well when dried [4]. Bred by Oregon nurseryman Andrew Van Hevelingen, it grows taller than Hidcote with 4-inch flower spikes that make outstanding dried bundles. The Missouri Botanical Garden rates it for Zones 5–8 with highly aromatic flowers and foliage [4]. Worth noting: the Missouri Botanical Garden cautions that it struggles in St. Louis-area humidity, so pair it with gravel mulch and raised planting in the humid Midwest [4].

4. Ellagance Series (Purple / Ice / Pink / Sky)

Height: 12–15 in | Zones: 5–8 | Colour: Purple, white, pink, blue | Scent: 3/5 | Best for: Containers, edging, first-year colour

The Ellagance series is unusual among English lavenders because it’s seed-grown — meaning it blooms in its first year from spring sowing, unlike most cultivars that need a full season to establish. The four colours (Purple, Ice/white, Pink, Sky/pale blue) can be massed for rainbow border effects or grown individually in matching containers. Compact habit at 12–15 inches suits window boxes and small pots well.

5. Melissa

Height: 18 in | Zones: 5–8 | Colour: Soft blush pink | Scent: 3/5 | Best for: Cottage gardens, mixed pots, cut flowers

True pink lavender is rare — most so-called pinks are a faded lilac. Melissa is one of the genuine soft-pink English lavenders, producing pale blush flower spikes on silver-grey foliage. It’s less commonly stocked than Hidcote or Munstead, but worth seeking out through specialist lavender nurseries. The USLGA notes that many growers underestimate pink varieties; they photograph exceptionally well and attract attention from visitors [7].

6. Nana Alba

Height: 10–12 in | Zones: 5–8 | Colour: White | Scent: 2/5 | Best for: White-themed borders, rock gardens, small pots

The best compact white English lavender. Nana Alba grows to a tidy 10–12 inches with pale silvery foliage and clean white flower spikes. White-flowered lavenders have slightly lighter fragrance than their purple counterparts — the linalool concentration is lower — but Nana Alba makes a striking contrast when planted alongside deep purple Hidcote. Excellent for formal edging in small gardens.

7. Blue Cushion

Height: 8 in | Zones: 5–8 | Colour: Violet-blue (paling as it matures) | Scent: 3/5 | Best for: Ultra-compact containers, rock gardens, front-of-border

Blue Cushion is among the smallest English lavenders available, forming a dense 8-inch mound of deep violet-blue flowers that lighten to pale blue as they open. Notably, it’s more tolerant of moister growing conditions than most angustifolias — a useful trait for gardeners in areas with wetter summers. It’s the go-to choice for 6-inch patio pots or planting at the very front of a rock garden, where its cushion habit is an asset rather than a compromise.

8. Folgate

Height: 26–30 in | Zones: 5–8 | Colour: Deep purple | Scent: 4/5 | Best for: Early harvest, cut flowers, craft wreaths

Folgate is the earliest-blooming English lavender on most US lavender farms — typically opening in late June, two to three weeks before Grosso and other lavandin hybrids. Commercial growers prize it for extending the harvest window. The USLGA recommends Folgate, Royal Velvet, and Buena Vista for craft operations specifically because their dark colours hold through the drying process [7]. As a landscape plant, its taller habit and strong fragrance make it excellent for cutting gardens.

9. Miss Katherine

Height: 20–24 in | Zones: 5–8 | Colour: Deep pink with orange throat | Scent: 4/5 | Best for: Cottage gardens, pots, mixed borders

The deepest-coloured pink English lavender in general commerce, and one of the tallest — its 14–16-inch stems spray outward elegantly, making it a distinctive cut flower. Miss Katherine received an RHS Award of Garden Merit in 2002. It’s the pink lavender of choice when you want something more vibrant than the typical pale blush — the slight orange throat adds warmth to the flower that photographs beautifully.

10. Imperial Gem

Height: 24–30 in | Zones: 5–8 | Colour: Rich dark purple | Scent: 4/5 | Best for: Cut flowers, tall border accent, low hedges

Imperial Gem grows taller than Hidcote while keeping a similar deep purple colour. The extra stem length — often 12–14 inches for the flower spike alone — makes it outstanding for cutting and drying. It holds its colour well in arrangements and has reliable winter hardiness to Zone 5. For gardeners who want Hidcote’s deep colour at a border mid-height, Imperial Gem is the obvious choice.

Lavandin Hybrids (Lavandula × intermedia) — Zones 5–9

Lavandin is a sterile hybrid between L. angustifolia and L. latifolia (spike lavender). The key difference from English lavender isn’t just size — it’s chemistry. Lavandin contains 5–15% camphor compared to angustifolia’s sub-1%. That camphor content is why lavandin smells stronger and more medicinal, why it dominates global essential oil production, and why it should not be used for cooking [7]. NC State Extension lists all lavandin for Zones 5a–8b with a 2–3-foot mounding habit and July–September bloom [2]. The later bloom time is a real advantage — it extends lavender season in the garden by four to six weeks after English lavenders have finished.

11. Grosso

Height: 24–36 in | Zones: 5–9 | Colour: Violet-purple | Scent: 5/5 | Best for: Oil production, dried flowers, tall hedges, wands

Grosso is the most commercially planted lavender in the world. In the Pacific Northwest, an acre of Grosso yields 3,500–4,500 pounds of dried flowers or 53–67 pounds of essential oil — approximately five times the yield of an acre of angustifolia [7]. That figure explains why virtually all the lavender oil in mass-market products is lavandin. As a garden plant, Grosso is exceptional: long 3–4-inch spikes on 12–14-inch stems (perfect for wand-making), intense fragrance, and a vigorous sprawling habit suited to informal hedges and mass planting. The USLGA recommends Grosso for craft operations specifically for its stem length [7].

12. Phenomenal

Height: 24–32 in | Zones: 5–9 | Colour: Violet-blue | Scent: 5/5 | Best for: Humid SE gardens, cold Zone 5, disease-resistant borders

Phenomenal is the most significant lavender introduction of the past decade for US gardeners in challenging climates. Developed by Peace Tree Farm in Pennsylvania and patented in 2013, it was specifically selected for performance where other lavandins fail: the humid Mid-Atlantic and Southeast [6]. Tony Avent of Plant Delights Nursery — who trialed it across multiple sites including Zone 8 North Carolina — stated it outperformed every other lavandin tested for heat and humidity tolerance [6]. It also survives temperatures to -10°F (Zone 5), making it uniquely adapted across a wider US climate range than any other lavandin. If you’re in Virginia, Georgia, or anywhere with summer humidity above 60%, Phenomenal is your default lavandin choice.

13. Provence

Height: 24–36 in | Zones: 5–9 | Colour: Soft lavender-purple | Scent: 4/5 | Best for: Culinary products, sachets, humid conditions

Provence carries the classic Provençal lavender scent — softer and more rounded than Grosso, with less of the sharp camphor edge. NC State Extension specifically lists Provence as ‘best for humid conditions’ among lavandin cultivars [2], making it a stronger choice than Grosso for gardeners east of the Mississippi. The USLGA recommends it for dried bud sales and sachets for superior bud colour and scent retention [7]. Despite being a lavandin, its mellower oil profile makes it the most popular lavandin for culinary-adjacent products like herb blends.

14. Dutch

Height: 28–36 in | Zones: 5–8 | Colour: Violet-blue | Scent: 4/5 | Best for: Tall informal hedges, screening, large borders

Dutch lavender is the tallest of the widely available lavandin cultivars, reaching 3 feet and spreading equally wide. It’s the default choice for gardeners wanting a lavender privacy hedge or tall screen along a fence line. The vigorous growth habit means it needs more room than English varieties — allow 3 feet between plants for hedging, 4 feet for specimens. Dutch blooms in mid-summer, after English lavenders have finished, extending the flowering display through August.

15. Edelweiss

Height: 30–36 in | Zones: 5–8 | Colour: White | Scent: 3/5 | Best for: White gardens, contrast borders, dried flowers

The only widely available white lavandin. Edelweiss (sometimes listed as ‘White Spike’) produces bright white flower spikes on tall 30–36-inch plants — larger and bolder than the white English lavender Nana Alba. It makes a dramatic contrast when planted alongside dark Grosso or Hidcote, and the white spikes dry well for arrangements. Less strongly scented than purple lavandins, but still aromatic.

16. Fred Boutin

Height: 18–24 in | Zones: 6–9 | Colour: Violet-purple to blue | Scent: 4/5 | Best for: Compact borders, cutting, scented gardens

Named after Fredrick C. Boutin, formerly a botanist at the Huntington Botanical Gardens, Fred Boutin is a more compact lavandin than Grosso or Dutch — topping out at 18–24 inches rather than 3 feet [5]. The Missouri Botanical Garden classifies it as ‘an excellent selection for cutting and drying’ with silver-green fragrant foliage and violet-purple blooms from mid to late summer [5]. It suits gardeners who want lavandin’s stronger scent and longer bloom in a size more typical of English lavender.

French and Spanish Lavender (Lavandula stoechas) — Zones 8–10

Lavandula stoechas is unmistakeable — the pineapple-like flower head topped with showy ‘rabbit-ear’ or ‘butterfly-wing’ bracts makes it one of the most visually distinctive lavenders. It blooms earlier than English lavender (often starting in March in Zone 8), keeps going through summer, and often rebounds with a second flush in autumn. The trade-off is hardiness: stoechas is reliably perennial only from Zone 8 upward. NC State Extension rates all stoechas for Zones 8a–9b [3]. In Zones 6–7, many gardeners grow it as a long-season annual or overwinter it in a frost-free greenhouse.

17. Anouk

Height: 18–24 in | Zones: 8–10 | Colour: Dark plum with blue-violet bracts | Scent: 3/5 | Best for: Long-season displays, pots, reblooming borders

Anouk is the most floriferous stoechas in regular commerce — NC State Extension lists it specifically for its ‘dark plum flower heads with blue-violet bracts’ and reliable reblooming [3]. The bracts are proportionally larger than the species, giving each flower head a more dramatic, wing-like appearance. It blooms from spring through autumn in Zone 8–9, making it the best stoechas for sheer season-length. Trim lightly after each flush to encourage the next one.

18. Kew Red

Height: 18–24 in | Zones: 8–10 | Colour: Cerise-pink bracts with pale flower | Scent: 2/5 | Best for: Unusual colour interest, containers, collectors

Kew Red is a genuine oddity in the lavender world — the bracts (the flag-like petal extensions) are a vivid cerise-pink rather than the usual purple. The flower body itself is pale, creating an unusual two-tone effect. It was first collected at Kew Gardens and remains one of the most sought-after stoechas for gardeners wanting something beyond purple. Scent is present but lighter than most lavenders — this one earns its place through visual impact rather than fragrance.

19. Fathead

Height: 18–24 in | Zones: 8–10 | Colour: Deep purple | Scent: 2/5 | Best for: Bold statement, containers, wildlife garden

Fathead has the largest flower heads of any stoechas cultivar — the rounded, almost spherical flower mass with proportionally enormous bracts gives it an almost tropical look. It’s a pollinators’ magnet: bumblebees love the extra-large landing platform. Useful in any warm-climate garden where you want a lavender that makes a statement from a distance.

20. Papillon

Height: 18–24 in | Zones: 8–10 | Colour: Purple with classic symmetrical bracts | Scent: 2/5 | Best for: Classic stoechas form, cottage gardens, pots

Papillon (French for butterfly) is the classic stoechas look — symmetrical, evenly proportioned bracts above a compact flower head. It’s the variety most gardeners picture when they think of French lavender. Less extreme in habit than Anouk or Fathead, it suits a traditional cottage border or a terracotta pot on a warm patio. Hardy to Zone 8 and long-flowering.

21. Ballerina

Height: 18–24 in | Zones: 8–10 | Colour: Bicolour — purple flower body, white bracts | Scent: 2/5 | Best for: Unusual bicolour effect, containers, contemporary gardens

NC State Extension lists Ballerina specifically for its ‘bi-color purple flowers with white flags’ [3] — the white bracts rising from the dark purple flower body create a crisp, clean two-tone effect unlike any other lavender. It’s the most contemporary-looking stoechas, well suited to minimalist or white-themed gardens. Grow in a pot to appreciate the flowers at close range.

Other Lavender Species Worth Growing

22. Lavandula dentata (French Lavender / Fringed Lavender)

Height: 24–36 in | Zones: 8–11 | Colour: Soft lavender-purple | Scent: 3/5 | Best for: Year-round interest (Zone 9+), evergreen hedging, long bloom

L. dentata — named for its distinctive toothed (dentate) leaf margins — is not a stoechas. It produces traditional lavender-style flower spikes but with serrated, almost comb-like grey-green foliage that looks good all year in frost-free climates. In Zone 9–10, it’s essentially evergreen and flowers almost continuously. The toothed leaves give it a fine texture distinct from any other lavender, making it an architectural choice for container work or as a soft hedge in the warm South and California.

23. Lavandula multifida (Fernleaf Lavender)

Height: 24 in plant, 36 in flower stems | Zones: 8–10 | Colour: Blue-purple | Scent: 3/5 | Best for: Foliage texture, warm borders, year-round structure

Fernleaf lavender has deeply dissected, lacy grey-green foliage unlike anything else in the genus — it looks more like a fern or fine-cut artemisia than a lavender. The flowers are small but freely produced on long wiry stems from spring through autumn. It fills a design gap in warm gardens, providing lavender fragrance and pollinator value with a completely different leaf texture. Zone 8 gardeners should plant in a sheltered spot with mulch protection.

24. Lavandula pinnata (Jagged Lavender)

Height: 18–24 in | Zones: 9–10 | Colour: Blue-purple | Scent: 2/5 | Best for: Containers (Zone 7+ overwinter indoors), foliage interest, tender perennial

The most tender of the species lavenders, L. pinnata is best treated as a container plant north of Zone 9, brought indoors when frost threatens. Its feathery, pinnate foliage has a slightly different structure from L. multifida and can bloom year-round in mild climates. It needs slightly more water than other lavenders — which makes it more forgiving in containers, where drying out is a greater risk. The scent is lighter but still present.

Best Lavender Varieties for Containers

Any lavender can grow in a container, but the following three were specifically bred or selected for compact container use. The key advantage of true dwarf lavenders in pots: they don’t outgrow a 10–12-inch pot, which maintains the all-important root-to-pot ratio that keeps drainage sharp. Given that lavender is also one of the best drought-tolerant flowers for a patio in dry spells, these varieties suit low-maintenance container gardening well.

25. Thumbelina Leigh

Height: 8–12 in | Zones: 5–8 | Colour: Violet-blue | Scent: 4/5 | Best for: Micro-pots, window boxes, edging, gifts

Thumbelina Leigh is the definitive dwarf English lavender for pots. At just 8–12 inches, it can be grown in a pot as small as 6 inches in diameter, though an 8–10-inch pot gives better root room and drainage. Despite its small size, scent is notably strong — the compact habit concentrates the aromatic oil rather than dispersing it across a large plant. It blooms continuously from early to mid-summer and is fully hardy to Zone 5. If you want lavender on a balcony, apartment patio or narrow window ledge, this is the one.

26. Little Lottie

Height: 12–18 in | Zones: 5–8 | Colour: Pale pink and white mixed | Scent: 3/5 | Best for: Pink-themed pots, small borders, cottage containers

Little Lottie (AGM, Royal Horticultural Society, 2002) produces an unusual mix of pale pink and white flowers on the same plant — individual spikes vary, creating a soft, mixed-tone effect. It’s one of the most popular English lavenders for containers thanks to its compact habit and the gentle colouring that works in pastel planting schemes. Spreads to about 2–3 feet, so allow space in the container for a second season’s growth.

27. Silver Mist

Height: 15–18 in | Zones: 5–8 | Colour: Pale lavender; standout silver-grey foliage | Scent: 2/5 | Best for: Foliage interest, silver-themed pots, winter containers

Silver Mist is grown primarily for its exceptionally silvery, intensely grey-green foliage rather than its flowers — the pale lavender spikes are secondary. In a container, the silver leaves catch morning light in a way that purple-flowered lavenders don’t. It maintains its foliage appearance through winter in Zones 5–8, making it useful for year-round container interest. Pair it with deep purple Hidcote or bright yellow rudbeckia for maximum contrast.

Best Lavender Varieties for Hedging

A lavender hedge works best when every plant is the same variety — mixing types creates uneven heights, different bloom times and an untidy appearance. For formal hedges under 24 inches, English lavenders are ideal. For taller informal hedges or screens above 30 inches, lavandin hybrids are the practical choice. Lavender also works as a companion plant alongside roses, where it deters aphids while providing a contrasting colour band at the border edge.

28. Hidcote (Low Formal Hedge)

Height: 18–20 in | Zones: 5–8 | Spacing: 12–15 in apart

Hidcote’s naturally compact, uniform habit makes it the default choice for a low formal lavender hedge. Plant 12–15 inches apart, allow two seasons to fill in, then clip immediately after flowering (never into old wood). A Hidcote hedge at the front of a rose border or along a path is a classic combination that has defined English garden style for a century. See full variety profile above.

29. Vera (Classic English Hedge)

Height: 30–36 in | Zones: 5–8 | Colour: Blue-purple | Scent: 4/5 | Best for: Taller English lavender hedge, oil production, classic borders

Vera is considered by many to be ‘true’ English lavender — a tall, vigorous L. angustifolia that grows to 3 feet and produces generous oil. The USLGA lists Vera alongside Hidcote Superior as the best angustifolia cultivars for essential oil quality [7]. As a hedge plant, it creates a taller, less clipped effect than Hidcote — more of a soft billowing mass than a precise edge. Allow 18–24 inches between plants for hedging. It has the sweet angustifolia scent profile with above-average stem length, making it useful for cutting as well.

30. Dutch (Tall Informal Hedge)

Height: 28–36 in | Zones: 5–8 | Spacing: 24–30 in apart

Dutch lavandin is the tallest lavender suitable for a garden hedge, creating a 3-foot fragrant screen that blooms in mid-summer after English lavenders have finished. It suits an informal, naturalistic style better than a clipped formal hedge — the sprawling growth habit means regular clipping after flowering (to one-third of the growth, never into brown wood) keeps it from collapsing in the centre. Space generously at 24–30 inches apart. See full variety profile above.

Master Comparison Table

How to Grow Lavender Successfully

Sun and Soil

All lavender species need a minimum of 6–8 hours of direct sun daily — shade causes thin, weak growth and minimal fragrance. Soil must drain sharply: lavender evolved on rocky Mediterranean hillsides where water moves through the root zone within minutes of rain [1]. In heavier soils, plant on a raised mound 12–24 inches above the surrounding ground level, or amend with horticultural grit or coarse sand at a ratio of one-third by volume. Target a pH of 6.5–7.5 — slightly alkaline soils suit all lavender species.

One thing that surprises many gardeners: lavender actively prefers low-fertility soil. High nitrogen causes lush, floppy growth with fewer flowers and weaker fragrance. Don’t fertilise established lavender unless a soil test shows a specific deficiency [2].

The Old Wood Rule — and Why It Matters

The single most common mistake that kills established lavender is cutting into the brown, woody base of the plant. This is not a horticultural preference — it’s a biological reality. Lavender stems develop a cork-like bark as they age that lacks the dormant growth buds present in green tissue. Unlike roses or buddleia, which regenerate readily from old wood, lavender cannot produce new shoots from brown stems. Cut below the green growth zone and the plant cannot recover [7].

The rule: prune immediately after flowering, removing up to one-third of the green growth, but always leave substantial leafy green growth below your cut. In autumn, resist the urge to cut back hard — wait until late spring when new basal growth confirms where the live zone is. If a plant has become severely woody from years of neglect, it’s typically better to replace it than attempt radical rejuvenation, which rarely succeeds.

Mulch: Gravel, Not Bark

Mediterranean-origin plants evolved with bare, rocky soil around their crowns — not the moist organic environment that bark mulch creates. A 1–2-inch layer of small crushed limestone or granite gravel around each plant achieves several things simultaneously: it reflects heat back up into the plant (mimicking rocky hillside conditions), allows rapid drainage away from the crown, and, in the case of limestone gravel, gradually raises pH toward the 6.5–7.5 ideal. Bark mulch retains moisture against the crown, creates the conditions for fungal root rot, and is the single most common avoidable cause of lavender failure in US gardens.

Choosing by US Climate Zone

For Zone 5–6 gardeners, stick to English lavenders (angustifolia) or Phenomenal — they’re the only lavenders proven reliably perennial at those temperatures. Lavandin can overwinter with protection (a loose layer of evergreen boughs, not fabric) but may die back hard in cold snaps. For Zone 7–8 with humid summers (Mid-Atlantic, Piedmont South), Phenomenal and Provence outperform other lavandin; standard Grosso and Dutch sometimes struggle with root and foliar disease in August humidity. Zone 9–10 opens up the full range — stoechas, dentata, multifida and pinnata all thrive alongside English and lavandin types. Specialist UK nurseries such as Norfolk Lavender also supply named varieties not always available from US suppliers, particularly rare angustifolia cultivars.

Frequently Asked Questions

What is the hardiest lavender variety for cold winters?

Hidcote and Munstead are the two most reliably hardy English lavenders, both rated to Zone 5 (-20°F). For lavandin in cold zones, Phenomenal is the standout choice — it has been trialed to Zone 5 and survives temperatures to -10°F while also tolerating summer humidity better than any other lavandin [6].

Which lavender is best for cooking?

Only Lavandula angustifolia cultivars are suitable for culinary use. Hidcote, Munstead and Melissa are the most popular. Lavandin (L. × intermedia varieties like Grosso and Phenomenal) contains significantly higher camphor levels — up to 15% — which creates a harsh, medicinal taste that is unpleasant in food [7]. The USLGA advises tasting the bud before using any lavender in recipes: ‘if it tastes good, it will taste good in your food’ [7].

Can lavender grow in containers?

Yes — in fact, containers often provide the sharp drainage that lavender needs but garden soil can’t always supply. Use a free-draining mix (combine standard potting mix with one-third perlite or coarse grit), and choose a pot with large drainage holes. The best container varieties are Thumbelina Leigh (8–12 in), Blue Cushion (8 in), Little Lottie (12–18 in) and the Ellagance series. Water only when the top inch of compost is dry, and empty saucers after rain to prevent root saturation.

Why is my lavender turning woody and not flowering well?

A lavender that’s woody at the base and producing fewer flowers is almost always under-pruned. Most lavenders need an annual clip immediately after flowering — removing one-third of the green growth — to keep producing vigorous flowering shoots. If you’ve missed a few years of pruning and the plant is mostly brown woody stems, it’s very difficult to recover: lavender cannot regenerate from old wood. For mildly woody plants, prune lightly each year over three seasons to gradually reduce the woody zone. For severely woody plants, replace them with a new plant and commit to annual pruning.

What is the difference between lavender and lavandin?

Lavandin (Lavandula × intermedia) is a sterile hybrid between English lavender (L. angustifolia) and spike lavender (L. latifolia). It grows larger, blooms later and produces 3–5 times more essential oil than English lavender — which is why it dominates commercial perfumery. However, its higher camphor content (5–15% vs less than 1% in angustifolia) makes it unsuitable for culinary use and gives it a stronger, more medicinal scent. For garden purposes: if you want bigger plants, stronger fragrance and a later bloom, choose lavandin. If you want sweet scent, culinary use and hardiness to Zone 5, choose English lavender.
