Allium hollandicum ‘Purple Sensation’ is an enduring favourite for a reason: statuesque stems topped with richly coloured, globe-shaped flower heads that bring poise and rhythm to late spring and early-summer borders. The grey-green basal foliage forms early, then quietly recedes as the blooms take centre stage—ideal for weaving through perennials and ornamental grasses.

Equally at home in generous pots, this fully hardy allium is particularly useful where soils are heavy; simply ensure excellent drainage and enjoy a refined, architectural display that also suits the vase.

Allium stipitatum 'Mount Everest' is a statuesque allium of exemplary poise, lifting perfectly rounded globes of crisp white, star-shaped flowers above grey-green foliage. In late spring and early summer, its tall, upright stems bring a clean, architectural note to borders and gravel planting, and the flower heads are equally superb in a vase.

Plant in generous drifts for a composed, contemporary look, or thread through perennials and ornamental grasses for height and rhythm. Once established, this perennial bulb returns with reliable presence and a polished finish.

Allium 'Giganteum' is a magnificent statement allium, lifting generous globes of lilac-pink flowers above the border on tall, assured stems. Its architectural scale gives late-spring planting a wonderfully considered air, while the individual starry florets remain light enough to mingle gracefully with perennials.

These premium 18/+ bulbs are particularly effective planted in measured groups through sunny borders. The flowers are much admired by pollinators, make superb cut stems and leave handsome seed heads for dried arrangements.

Allium sphaerocephalon is a wonderfully refined choice for extending the season with poise. Slender stems rise above neat, narrow foliage, each topped with a dense, rounded head in rich pink to red tones—an elegant punctuation mark through early to late summer.

Superb threaded through borders or planted en masse for a light, rhythmic effect, it also suits generous pots where its upright habit brings height without heaviness. A quietly hardworking perennial, it is also valued for being pollinator friendly.

Allium cristophii (Star of Persia) brings a composed sense of theatre to the late spring garden. Each stem carries a broad, shimmering head of rosy‑violet, star-shaped flowers—architectural without being overbearing, and particularly handsome rising through fresh greens at the front of a border.

As the colour softens, the seedheads remain beautifully sculptural, lending quiet structure well into summer. A natural choice for gravel gardens and contemporary planting schemes, and a superb subject for cutting and drying.

• Large, starry flower heads in May–June
• Excellent for cut flowers and long-lasting dried arrangements
• Pollinator friendly and notably deer resistant
• Fully hardy perennial—returns with increasing presence over time

Allium 'Gladiator' is a statuesque choice for adding modern architecture to late-spring planting. Each bulb sends up a tall, upright stem topped with a perfectly rounded globe of soft lavender-purple flowers—clean, contemporary and wonderfully composed among grasses, nepeta and early roses.

Its grey-green foliage forms a neat base before the flowerheads rise above the border, lending height and rhythm without fuss. An elegant performer in mixed planting, and a fine option for large containers where drainage is assured.

• Large, spherical flowerheads in refined lavender-purple
• Excellent for borders and statement containers
• Pollinator friendly and notably resilient to deer

Allium 'Globemaster' is the sort of bulb that brings instant composure to a planting scheme. In late spring, tall, steady stems carry magnificent, perfectly rounded heads of rich violet-purple, each globe composed of countless starry florets. Rising above grey-green foliage, it adds architectural rhythm through borders and naturalistic drifts, while offering a welcome pause of structure amongst softer perennials.

A refined choice for cottage gardens and smarter city courtyards alike, and particularly valuable where you’d like planting that quietly supports pollinators.

• Flowering: May–June
• Height: 80cm
• Bulb size supplied: 18/20cm

Allium amethystinum 'Red Mohican' PBR is a wonderfully characterful allium, bringing late-spring height and an artful, lightly tousled silhouette to the border.

Planted in generous drifts, it rises above emerging perennials to provide elegant structure in May and June, and it is a particularly fine choice where you’d like a little movement and pollinator interest woven through a planting scheme.
