20 Bi-Color and Striped Flowers That Look Too Striking to Be Real

A single-color flower bed is perfectly fine — until a striped tulip or a splash-patterned dahlia catches your eye and suddenly everything else looks plain. Bi-color flowers carry two or more distinct hues on the same bloom, and that built-in contrast does the design work for you: no complicated color-wheel planning, no fussy companion pairings.

The patterns themselves come from surprisingly elegant biology. Two pigment families — anthocyanins (reds, pinks, purples) and carotenoids (yellows, oranges) — are switched on or off in different petal cells by transcription factors that control where color appears, not just which color appears [1]. Small tweaks in those genetic switches produce stripes, picotee edges, star bursts, and bold central eyes — sometimes on the same species.

Below are 20 bi-color and striped flowers organized by their pattern type, so you can pick exactly the look your garden needs.

Quick Pattern Guide

Striped Flowers

1. Tulip (Tulipa spp.)

The most famous striped flowers in history owe their pattern to the tulip breaking virus (TBV), which suppresses anthocyanin production in random petal cells, leaving pale streaks where pigment should be [3]. During the 1630s Dutch Tulipomania, a single “broken” bulb could cost more than a canal house. Modern Rembrandt-type tulips like ‘Flaming Flag’ and ‘Rem’s Favourite’ reproduce the look through safe, stable genetics — no virus required. Plant bulbs 15 cm deep in autumn, in full sun and well-drained soil. Zones 3-8.

2. Rose — Rosa gallica ‘Versicolor’

Known since at least the 15th century, this gallica sport produces pale pink petals streaked and splashed with deep crimson. The pattern is a periclinal chimera — two genetically distinct cell layers in the shoot tip, each carrying different pigment instructions, stacked like a sandwich [5]. Because periclinal chimeras are stable, ‘Versicolor’ has been vegetatively propagated for over 500 years with reliable striping. ‘Ferdinand Pichard’ is a modern repeat-blooming alternative with similar candy-stripe markings. Both thrive in zones 4-9 and appreciate morning sun with afternoon shade in hot climates. For more rose varieties and care advice, see our complete rose care guide.

3. Verbena (Verbena x hybrida)

Superbena Stormburst types carry soft lavender-and-white striped florets in dense clusters that bloom from late spring through frost. Each individual floret is barely a centimetre across, but the cluster effect amplifies the stripe pattern into a showy dome. Verbena is powdery-mildew resistant, heat tolerant, and works as a groundcover or spiller in containers. Full sun, zones 7-11 (or treat as annual).

4. Petunia (Petunia x hybrida)

Striped petunias like ‘Burgundy Star’ and ‘Pinstripe’ display radiating white stripes on a saturated background — magenta, purple, or red. The pattern is genetically programmed through differential anthocyanin expression in alternating cell sectors. Deadheading is optional with modern spreading types; they self-clean and bloom continuously from spring through the first hard frost. Full sun, treat as annual in most zones.

Picotee-Edged Flowers

5. Dianthus — Fruit Punch ‘Cherry Vanilla’

A picotee pattern places a contrasting color at the petal edge with a sharp dividing line — no gradual fade. ‘Cherry Vanilla’ does this with deep red centers and a crisp light pink border on double, carnation-like blooms. The effect comes from anthocyanin concentration dropping abruptly near the petal margin, where a different set of transcription factors takes over. Fragrant, deer resistant, and evergreen in mild winters. Zones 4-9, full sun to part shade.

6. Lisianthus (Eustoma grandiflorum)

Lisianthus picotee varieties like ‘ABC Purple Picotee’ resemble ruffled roses with white petals rimmed in violet or pink. They are fussier than most flowers on this list — they need warm soil for germination, consistent moisture, and protection from wind — but the payoff is a cut flower that lasts two weeks in a vase. Zones 8-10 (grow as annual elsewhere), full sun.

7. Carnation (Dianthus caryophyllus)

Picotee carnations have been bred for the cut-flower trade for centuries. The ‘Chabaud’ series offers double blooms with sharply defined contrasting edges in combinations like white-and-red or yellow-and-pink. The mechanism is similar to other dianthus — abrupt shifts in MYB transcription factor activity near the petal margin [2]. Zones 6-9, full sun, well-drained alkaline soil.

Star and Pinwheel Patterns

8. Calibrachoa — Superbells ‘Lemon Slice’

‘Lemon Slice’ displays alternating sunny yellow and creamy white wedges radiating from the center like a pinwheel. The pattern holds all season, even in heat. Calibrachoa needs acidic soil (pH 5.5-6.0) and iron-rich fertilizer — chlorosis is the most common failure mode. Excellent for hanging baskets. Full sun, zones 9-11 (annual elsewhere).

9. Phlox (Phlox paniculata)

‘Peppermint Twist’ carries pink-and-white pinwheel-patterned florets on tall panicles through midsummer. The bicolor effect comes from sector-specific pigmentation — genetically identical cells expressing anthocyanin in some sectors and suppressing it in others. Space plants 45 cm apart for air circulation to prevent powdery mildew. Zones 4-8, full sun to light shade.

10. Clematis (Clematis spp.)

‘Nelly Moser’ opens with pale mauve petals carrying a bold pink central bar on each tepal — a natural star pattern. The bar intensifies in partial shade and fades in full sun, which is why this cultivar performs best on an east-facing wall. Zones 4-9, part shade preferred.

Eye and Zone Patterns

11. Gazania (Gazania rigens)

Gazanias pack more visual contrast per square centimetre than almost any other annual. Each daisy-like bloom has a bold dark ring surrounding the central disc, with ray petals in yellow, orange, red, or cream radiating outward. The dark zone is an anthocyanin-rich band where pigment expression is locally amplified [1]. They close in shade, so plant in full sun. Drought tolerant once established. Zones 9-11 (annual elsewhere).

12. Painted Daisy (Tanacetum coccineum)

Also sold as Chrysanthemum coccineum, painted daisies carry concentric bands of red, pink, or white around a bright yellow center — a natural target pattern. The banding reflects zone-specific transcription factor activity in concentric rings of petal tissue. They bloom in early summer, attract beneficial insects, and naturalize easily in well-drained soil. Zones 3-7, full sun.

13. Sunflower — ‘Ring of Fire’ (Helianthus annuus)

‘Ring of Fire’ earns its name with a broad red-mahogany ring surrounding a dark disc, fading to golden-yellow tips. The bicolor zone pattern is genetically stable and consistent across the plant’s 120-150 cm height. For branching types with multiple bicolor heads, try ‘Florenza’ or ‘Magic Roundabout’. Full sun, direct sow after last frost. For growing tips and variety picks, see our complete sunflower growing guide.

14. Black-Eyed Susan — ‘Cherry Brandy’ (Rudbeckia hirta)

Most rudbeckias are solid gold, but ‘Cherry Brandy’ introduces deep cherry-red petals surrounding a chocolate cone — a striking eye-zone reversal where the outer petals carry the darker pigment. It blooms the first year from seed and flowers from midsummer until frost. Short-lived perennial in zones 3-7, full sun, tolerates poor soil.

Splash and Fleck Patterns

15. Dahlia — ‘Twynings Smartie’

Splash-patterned dahlias carry irregular, unpredictable patches of contrasting color — no two blooms look alike. ‘Twynings Smartie’ throws white single flowers randomly streaked and spotted with pink and magenta. The randomness comes from mericlinal chimera events: a mutation in part of one cell layer during bud development, producing sectors of different genotypes within the same flower [5]. The instability is the charm — each bloom is unique. Lift tubers after first frost in zones colder than 8. Full sun.

16. Camellia — Camellia japonica ‘Lavinia Maggi’

‘Lavinia Maggi’ opens formal double blooms of white marbled with pink and crimson streaks — the pattern varies from flower to flower on the same shrub. The RHS notes that these irregular markings arise from genetic mutations during early flower development, probably at the two-cell stage [4]. Hardy to zone 7, this slow-growing evergreen shrub prefers acidic soil (pH 5.0-6.5), dappled shade, and shelter from cold morning sun that damages frosted buds.

Bicolor Form — Different Colors on Different Petals

17. Iris — Tall Bearded Types (Iris germanica)

Bearded irises split their color between two petal groups: upright “standards” and drooping “falls.” A bicolor iris carries distinctly different hues on each — pale blue standards over deep purple falls, or butter-yellow standards over mahogany falls. ‘Edith Wolford’ (yellow/blue-violet) is a classic example. The genetic control is straightforward: separate sets of regulatory genes govern pigment expression in the dorsal vs. ventral petal primordia. Zones 3-9, full sun, well-drained soil. Plant rhizomes with the top exposed.

18. Columbine (Aquilegia spp.)

Columbines produce bicolor blooms with different colors on the outer spurs and inner corolla — red spurs with yellow centers in the native A. canadensis, or blue spurs with white centers in A. caerulea. The Songbird and McKana Giants series offer the widest bicolor range. They self-sow freely and bloom in late spring. Zones 3-8, part shade to full sun.

19. Pansy (Viola x wittrockiana)

Pansies are the most familiar bicolor flower in temperate gardens. The dark central “face” blotch is created by localized anthocyanin overexpression in the two lower petals, guided by venation-pattern signals that direct pigment toward the throat [2]. ‘Morpho’ and ‘Cats’ series maximize the contrast. Cool-season performers — plant in early spring or autumn. Zones 4-8, full sun to part shade.

20. Snapdragon (Antirrhinum majus)

Bicolor snapdragons like the ‘Madame Butterfly’ series carry two distinct colors — typically a pale throat graduating to a saturated lip in red, bronze, pink, or yellow. The flower’s hinged structure amplifies the effect: when a bee opens the “jaw,” the hidden interior reveals a contrasting shade. They perform best in cool weather, flowering from spring to early summer and again in autumn. Zones 7-10, full sun.

Design Tips for Bi-Color Flower Beds

Let one bicolor flower anchor the palette. Pick the bloom with the highest contrast (gazania, dahlia, or striped tulip) and echo its secondary color with solid-toned companions. A ‘Ring of Fire’ sunflower, for instance, pairs with solid yellow coreopsis and burgundy helenium — the two colors already present in the bloom.

Mass a single bicolor variety rather than mixing several different two-toned flowers. Three or more different bicolor patterns in one bed compete for attention and create visual noise. One striped petunia variety filling a window box reads as intentional; three different bicolor species reads as chaotic.

Use neutral foliage as a frame. Silver-leaved plants like lamb’s ear (Stachys byzantina) or dusty miller calm the visual intensity of bi-color blooms. Green foliage works too, but silver provides the strongest contrast reset.

Why Are Some Bi-Color Patterns Stable and Others Not?

Gardeners often notice that the same dahlia plant throws different patterns each year, while a striped rose looks identical decade after decade. The reason is the biological mechanism behind the pattern:

Genetically programmed patterns — like the star markings on petunias, the concentric rings on painted daisies, or the bicolor standards-and-falls on iris — are written into the plant’s DNA and reproduce faithfully from seed or division. These patterns are controlled by transcription factors that activate or suppress pigment genes in specific petal zones [1][2].

Chimeral patterns — like the stripes on Rosa gallica ‘Versicolor’ — depend on two genetically distinct cell layers stacked in the shoot tip. Periclinal chimeras are stable enough for vegetative propagation, which is why ‘Versicolor’ has been cloned reliably for centuries. But mericlinal chimeras (partial-layer mutations) are unstable, producing the unpredictable splash patterns seen in dahlias like ‘Twynings Smartie’ [5].

Virus-induced patterns — the original tulip “breaks” — are caused by TBV suppressing anthocyanin synthesis in random cell clusters. These patterns are inherently unstable, weaken the plant over time, and should be avoided. Modern “Rembrandt” tulips are bred for the same look without the virus [3].

Frequently Asked Questions

What causes a flower to be bi-color?

Most bi-color patterns are genetic — transcription factors switch pigment-producing genes on in some petal cells and off in others. The RHS notes that some spontaneous bicoloring comes from random mutations early in flower development, probably at the two-cell stage [4]. Others are chimeras (two genotypes in one plant) or, historically, virus-induced.

Do bi-color flowers come true from seed?

Genetically stable patterns (petunia stars, gazania eyes, iris bicolors) generally reproduce from seed, though exact ratios vary. Chimeral patterns (striped roses, splashed camellias) do not come true from seed — they must be propagated by cuttings, grafting, or division.

Are striped tulips safe to grow?

Modern Rembrandt-style tulips sold by reputable nurseries are virus-free and safe for any garden. The tulip breaking virus that caused the original stripes during Tulipomania weakens and eventually kills the bulb — avoid planting truly broken tulbs from unverified sources near healthy tulip beds, as aphids transmit TBV [3].

Which bi-color flower is easiest to grow?

Gazanias and zinnias are the most forgiving — direct sow after last frost, provide full sun, and both bloom within 60-75 days. Petunias and calibrachoa are nearly as easy in containers with consistent feeding.
