Striped squill

Sun

Full sun to partial shade; suitable beneath deciduous trees that admit light in early spring.

Water

Keep soil moderately moist during autumn rooting and spring growth. Once dormant in summer, established bulbs need little additional water; avoid persistently wet ground.

Soil

Well-drained soil with some organic matter; tolerates chalk and a range of soil pH levels. Avoid compacted, waterlogged clay.

Height

0.3-0.7 ft (0.1-0.2 m)

Spread

0.2-0.3 ft (0.05-0.1 m) per bulb, forming wider colonies over time

Flowers

Early to mid-spring; pale blue to nearly white flowers with a darker blue stripe along each petal-like segment.

Foliage

A few narrow, fleshy, strap-shaped green leaves emerge around flowering time and die back by early summer.

Growth

Moderate; clumps expand gradually through offsets and self-seeding.

Growth rate

Moderate

• Plant bulbs in autumn, about 3 in (8 cm) deep and 2-3 in (5-8 cm) apart.
• Water after planting and during prolonged dry spells while leaves are growing.
• Top-dress with a thin layer of compost in autumn; rich soil rarely needs additional fertiliser.
• Leave the foliage until it turns yellow naturally, and delay mowing naturalised patches until then.
• Lift and separate crowded clumps after the foliage dies back, replanting the bulbs promptly.

Pruning. No pruning is needed beyond removing yellowed foliage. Snip off spent flower stems before seed capsules ripen if you want to limit self-seeding.

Autumn

Plant bulbs in well-drained ground and water them in.

Late autumn

Apply a thin compost mulch without leaving a thick, wet layer over the planting.

Early spring

Water during extended dry weather while shoots and flowers are developing.

Mid-spring

Remove fading flower stems if seedlings are not wanted; otherwise allow seed capsules to develop.

Late spring

Let leaves yellow completely before cutting them back or mowing nearby grass.

Summer

Divide crowded dormant clumps if needed and avoid unnecessary irrigation over resting bulbs.

• Plant in loose drifts beneath deciduous shrubs and trees for colour before the canopy closes.
• Use along path edges or at the front of borders, where the small striped flowers can be seen closely.
• Tuck into rock gardens with gritty drainage and low-growing spring plants.
• Naturalise in lightly shaded grass that can remain unmown until the bulb foliage dies back.
• Combine with later-emerging perennials that cover the bare ground after summer dormancy.

Garden styles it suits: Woodland, Cottage garden, English country, Alpine rock garden, Low-maintenance and Blues and silvers.

Plant it with: Snowdrops, Crocuses, Dwarf daffodils, Hellebores, Brunnera and Hostas.

Wildlife: The early flowers provide nectar and pollen for bees active in cool spring weather.

• Bulb rot in waterlogged soil: improve drainage or move bulbs to a raised bed; discard soft, decaying bulbs.
• Slugs and snails eating emerging growth: check shoots during damp weather and use traps or locally approved controls if damage is significant.
• Poor flowering after premature leaf removal: allow leaves to die back naturally so bulbs can replenish their reserves.
• Unwanted seedlings: remove flower stems before seed ripens and lift stray bulbs while their foliage is visible.

Not known to be toxic, but reliable species-specific information for people, cats, dogs and horses is limited. No particular toxic part or severity is established; do not treat the bulbs, leaves or flowers as edible.

• Siberian squill (Scilla siberica)

  Usually has deeper blue, nodding flowers without the conspicuous pale background and narrow blue stripe of striped squill.

• Glory-of-the-snow (Scilla luciliae)

  Has more open, upward-facing blue flowers with a distinct white central eye rather than a blue stripe along each segment.

Puschkinia honours the Russian botanist Apollo Mussin-Pushkin, while scilloides means resembling Scilla, the squills.

Propagation. Separate bulb offsets after the foliage dies back and replant promptly. Alternatively, sow ripe seed outdoors in pots and leave exposed to seasonal cold; seedlings take several years to reach flowering size.

Accepted botanical name

Puschkinia scilloides

Native range

Iran, Iraq, Lebanon-Syria, North Caucasus, Transcaucasus and Turkey.

Measured

Average height 25 cm.
