What to Plant with Tulips: 10 Companions That Deter Pests, Hide Dying Foliage, and Bloom in Sequence

Most gardeners pick tulip companions for spring color. The better question is what happens in the six weeks after the blooms are gone—when tulip leaves turn limp, yellow, and unsightly but cannot be cut without wrecking next season’s flowers. The companions chosen for that window are the ones that actually earn their place.

There’s a second problem few companion-planting guides address: squirrels treat a tulip bed like a buried snack cache. The right neighboring plants change the chemistry of the whole bed, making it far less appealing to anything digging from below.

This guide organizes tulip companions around three phases of the tulip lifecycle—bulb protection underground, simultaneous bloom, and post-bloom foliage coverage—and explains the mechanism behind each recommendation rather than just listing names.

Why the 6-Week Foliage Window Changes Everything

After tulip flowers fade, the leaves switch roles. They’re no longer decoration—they’re the factory that recharges the bulb for next year. Through photosynthesis, green tulip leaves convert sunlight into carbohydrates stored in the bulb’s fleshy scales. According to Gardening Know How, this process takes six to eight weeks, and any interference—cutting, tying, or braiding the leaves—reduces photosynthesis and directly limits the following spring’s blooms [3].

That’s why “fills the gap after tulips fade” is the most important criterion for a tulip companion. Plants that emerge quickly in late spring and grow tall enough to visually overtake the declining tulip foliage are not just aesthetic cover—they’re functional protection for a process that must be allowed to complete.

Deadheading tulips promptly after flowering does help: removing the spent flower head redirects energy away from seed production and back into the bulb [3]. Companions that distract from fading foliage while leaving the leaves intact and in sunlight are doing the real work.

Companions That Protect Tulip Bulbs Underground

Tulips are among the most squirrel-raided bulbs in any garden. Plant these alongside them and you change the olfactory profile of the entire bed.

Daffodils (Narcissus)

Daffodils are the single most effective tulip bodyguard, and the RHS specifically recommends interplanting them to reduce grey squirrel damage [1]. The mechanism is chemical: every part of a daffodil plant contains lycorine, a bitter alkaloid that is toxic to mammals including squirrels and voles. Because squirrels locate buried food by scent, a dense planting of lycorine-rich daffodil bulbs masks the appealing odors from nearby tulip bulbs—making the whole bed smell unappealing rather than just one section of it [2].

Lycorine remains bound within the daffodil’s cellular tissue until the plant is physically crushed, so neighboring tulip roots grow directly alongside daffodil roots with no allelopathic risk—they share soil comfortably [2].

Plant both at the same time in autumn at the same depth. Good cultivar choices that bloom in sequence with mid-season tulips: ‘Ice Follies’ (white, early), ‘King Alfred’ (yellow, mid-season), or ‘Thalia’ (white, elegant) for zones 3–9. For a deeper look at daffodil varieties and planting depths, our daffodil growing guide covers the full range.

Ornamental Alliums

Alliums are tulips’ most useful bloom-extending companion. They deter squirrels through allicin and sulfur compounds released from their foliage and tough papery bulb skins—the same chemistry that makes onions and garlic unpleasant to most rodents [2]. Unlike daffodils, alliums bloom several weeks after tulips, so they keep color in the bed through late spring and into early summer when tulips have long finished.

Height range is enormous: ‘Blue Drumstick’ (Allium caeruleum) stays compact at 12–18 inches, ‘Purple Sensation’ reaches 24–30 inches, and ‘Globemaster’ towers to 36 inches with 10-inch purple spheres. For a spring border with a succession of color, combine early-blooming tulips with mid-height alliums and let the alliums carry the show into June. All are perennial in zones 4–10 and naturalise well [4]. See our collection of purple flowers for spring and summer for more allium variety ideas.

Grape Hyacinth (Muscari)

Grape hyacinths bloom at the same time as early and mid-season tulips and are deterring to squirrels through saponins and a persistent musky smell [2]. At 6–9 inches tall they act as a dense low underplanting that fills the bare soil between taller tulip stems. They naturalise aggressively—plant them once and divide every few years to prevent overcrowding. Zones 4–8.

Companions That Bloom Simultaneously

Forget-Me-Nots (Myosotis sylvatica)

Forget-me-nots are the classic tulip partner and the RHS lists them as a direct recommendation for underplanting tulip borders [1]. The pairing works because of timing: sow forget-me-not seeds or transplant seedlings directly over tulip bulbs in September or October. The following spring, the blue carpet emerges simultaneously with tulip stems, providing a continuous color background that makes tulip shades appear more saturated and intentional by contrast.

Late-blooming tulip varieties—‘Angelique’ (pale pink double), ‘Queen of Night’ (deep maroon), or ‘Black Hero’ (near-black)—pair particularly well because their bloom window aligns with peak Myosotis flowering in May. Forget-me-nots are cool-season plants that self-seed and fade before summer heat arrives, conveniently leaving space exactly when tulip foliage needs maximum sun exposure to complete photosynthesis. They prefer moist, cool conditions—a natural match to the spring climate when tulips bloom. For blue flowers that bloom alongside or after spring bulbs, see our guide to true blue garden flowers.

Pansies and Violas

Pansies tolerate the same cool-season conditions as tulips and stay low enough (6–10 inches) to not compete for light. The RHS includes them as a direct underplanting recommendation [1]. Choose single-color or bicolor pansies that contrast with your tulip palette—deep purple violas under orange or yellow tulips create sharp visual impact without crowding. Pansies are annuals in most US zones but perform as perennials in zones 9–10.

Creeping Phlox (Phlox subulata)

For the front edge of a tulip bed, creeping phlox creates a 4–6 inch carpet of color that blooms in April and May alongside tulips. It’s drought-tolerant once established—important because excess summer moisture rots tulip bulbs—and spreads gradually to fill gaps without becoming invasive. Hardy in zones 3–9, it also holds soil on slopes where bulbs tend to wash.

Companions That Cover Dying Foliage

This phase is where most gardeners make the same mistake: they cut the foliage too soon because it looks untidy. The right perennials make this a non-issue by growing tall and dense enough to visually overtake the dying leaves within two or three weeks of bloom ending.

Daylilies (Hemerocallis)

Daylilies are the most reliable post-tulip foliage cover available. Their strap-like leaves emerge quickly in late spring, grow tall enough to hide yellowing tulip foliage within a few weeks, and then flower from June through July once the tulips are fully dormant [4]. They’re drought-tolerant once established—meaning you won’t be overwatering in summer and rotting tulip bulbs in the process. Zones 3–9, and most cultivars naturalise generously. Plant daylilies directly behind or beside tulip clumps so their emerging foliage overlaps the fading tulip leaves from the back of the border.

Hostas

For tulip beds that receive morning sun but afternoon shade—a common situation under deciduous trees—hostas are the strongest foliage cover. They emerge in late spring, and their broad leaves completely obscure dying tulip foliage once they reach full size. The key caveat: hostas need reliable moisture through summer, which can be risky for tulip bulbs. Choose a planting arrangement where hostas receive irrigation at their outer edges but the soil near the tulip bulbs stays relatively dry, or lift the bulbs for summer storage if the bed will be heavily watered. Zones 3–9.

Karl Foerster Feather Reed Grass

‘Karl Foerster’ (Calamagrostis acutiflora) is the most useful ornamental grass for tulip beds [5]. It emerges in late spring with upright, architectural foliage that provides vertical structure and fills mid-border space as tulips fade. Drought-tolerant, zones 4–9, reaching 4–5 feet by midsummer. Unlike many grasses, it stays tidy through winter without flopping, and the feathery plumes persist until spring when they’re cut back just before tulip bulbs begin pushing growth again.

Annuals for Quick Gap-Filling

Nasturtiums

Nasturtiums do something no other annual companion achieves: they repel aphids, which are tulips’ primary insect pest [4]. Direct-sow between tulips as the flowers start to fade—nasturtiums germinate in 7–10 days and grow fast enough to fill gaps before foliage becomes unsightly. Their roots are shallow and won’t disturb bulbs below [4]. Both leaves and flowers are edible, making them one of the most versatile additions to any spring border.

Sweet Alyssum (Lobularia maritima)

Sweet alyssum carpets the soil surface at 3–9 inches with honey-scented white or pink flowers that attract parasitoid wasps and syrphid flies. These beneficial insects control aphids and other small pests throughout the season. Shallow roots cause no bulb competition, and alyssum tolerates drought once established—safe for summer-dormant tulip beds. Zones 5–10 as annual; self-seeds reliably in most gardens.

What to Avoid Planting With Tulips

The primary risk is excess moisture in summer when tulip bulbs are dormant. Plants that require frequent irrigation—mint, astilbe, cardinal flower, and many ferns—create conditions that promote fungal bulb rot. Avoid anything that will be watered heavily from June through September in the same soil zone as the tulip bulbs.

Fennel (Foeniculum vulgare) is another problem: it releases trans-anethole and fenchone from root exudates, which inhibit neighboring plants’ root growth. Keep fennel at least five feet away from any bulb bed.

Heavy feeders like dahlias and cannas that need rich, moist soil through summer are also poor companions. The tulip bulb’s summer dormancy requirement is the non-negotiable starting point: if a companion plant needs regular summer water, it doesn’t belong in the same planting zone.

Frequently Asked Questions

Can tulips be planted with perennials?

Yes—perennials are often the best long-term companions because they return each year and gradually grow to cover more of the post-bloom gap. Daylilies, hostas, creeping phlox, and ornamental grasses all work well. The key requirement: choose perennials that tolerate dry conditions in summer, when tulip bulbs are dormant and watering should be minimal.

What hides dying tulip leaves best?

Daylilies are the most reliable option in full-sun beds. Their foliage emerges fast in late spring and grows directly over the fading tulip leaves within two to three weeks of bloom ending. In part-shade settings, hostas with their broad leaves provide better coverage. In either case, plant the companion directly beside or behind the tulip clumps so growth overlaps the declining foliage naturally.

Do daffodils really protect tulip bulbs from squirrels?

In practice, yes. The protection is chemical: daffodil bulbs contain lycorine, a bitter alkaloid that squirrels detect by scent. A dense interplanting of daffodils masks the appealing scent of nearby tulip bulbs, making the whole bed less attractive to digging. The RHS recommends this specifically for squirrel-prone gardens [1]. It’s not a guarantee—a determined squirrel may still investigate—but it significantly reduces the frequency of damage. See our squirrel-proof garden guide for additional strategies.

What are the best companion plants for tulips in pots?

Pansies, grape hyacinths, and forget-me-nots are the best container companions. All three are shallow-rooted, cool-season plants that won’t compete with tulip bulbs in a confined space. Plant tulip bulbs in the bottom layer of the container in autumn, then add pansies or sow forget-me-not seeds in the top layer. They’ll bloom simultaneously the following spring.
