White Alliums

Allium nigrum is a quietly dramatic allium: creamy-white, cup-shaped flower heads with a distinctive dark central eye, held on sturdy stems above neat, grey-green foliage. Flowering in late spring into early summer, it brings a composed lift to borders and gravel planting, and lends itself beautifully to elegant, architectural arrangements indoors.

• Refined colour – creamy white with green centres and a deep, inky focal point
• Excellent structure – upright stems with crisp, modern presence
• Garden & vase – a handsome cut flower with lasting style
• Wildlife-friendly – pollinator friendly
• Dependable – fully hardy and straightforward to grow

Plant in autumn for a poised display in May and June, then allow the foliage to fade naturally to feed the bulb for next year’s performance.

Allium stipitatum 'White Giant' brings a poised, architectural note to late spring borders—tall, confident stems topped with dense, starry white spheres that float above fresh green foliage. It is a quietly glamorous choice for contemporary planting schemes and classic cottage-style gardens alike, and it cuts beautifully for arrangements.

Plant in autumn in a sunny, well-drained position and allow the bulbs to naturalise into handsome clumps. As the flower heads rise in May and June, they provide an elegant vertical accent among perennials and grasses, while also offering welcome interest to pollinators.

• Colour & form: star-shaped white flowers in rounded heads
• Height: 110–150cm; a refined, statuesque presence
• Where it shines: borders, pots, and as a cut flower

Allium 'Silver Spring' brings a composed, architectural note to the late-spring border. Each tall stem is topped with a crisp white globe, the individual florets finished with a subtle purple‑pink eye—fresh, modern, and quietly striking among grasses, perennials and shrubs.

Equally at home threading through a cottage scheme or punctuating gravel planting, it also makes a refined cut flower, holding its form beautifully in arrangements. Plant in autumn and allow it to settle; by its second season it will be hitting its stride.

• Flower colour: white with soft pink‑purple detailing
• Best for: borders, gravel gardens, naturalising and cutting
• Style notes: elegant globes for height and structure without heaviness

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.

• Colour: White with a light green flush
• Flower shape: Globe
• Excellent for: Borders, gravel gardens and cut flowers

Allium cowanii (Neapolitan garlic, Cowanii Group) is a quietly captivating allium, sending up loose, airy umbels of pure white, starry flowers on slender stems. Flowering in late spring and early summer, it brings a clean, lifted note to borders, gravel planting and pots—especially effective when threaded through grasses or soft, cottage-style perennials.

Compact and clump-forming, it settles in with ease and returns reliably year after year. Plant in autumn for an elegant drift of white that also proves popular with pollinators.

• Flower colour: White
• Flowering period: May–June
• Best for: Borders, containers, cottage gardens, city gardens
• Character: Airy, star-shaped flowers with a refined, natural look

Allium neapolitanum is a smaller, exquisitely poised allium, prized for its crisp white, star-shaped blooms gathered into neat umbels. Held on slender stems above fresh mid-green foliage, it brings a clean, luminous note to gravel planting, sun-baked edges and beautifully finished pots.

Particularly useful where winter wet makes heavier ground unreliable, this is a quietly confident choice for raised beds and containers—easy to place, and all the more elegant when planted in generous drifts.

• Flower colour: White
• Form: Star-shaped umbels on neat stems
• Ideal for: Containers, gravel gardens, courtyards and borders
• Wildlife: Pollinator friendly

Allium ursinum (ramsons) is a charming native allium, prized for its broad, fresh green leaves and neat, starry white flowers in spring. It is particularly well suited to lightly shaded corners and woodland-style planting, where it will naturalise beautifully and, in time, form handsome colonies.

For an elegant, relaxed effect, tuck the bulbs beneath deciduous trees or along the edge of a shady path, where the display can return with quiet reliability each year.

• Colour & form: star-shaped white flowers over mid green foliage
• Best for: woodland gardens, naturalising and ground cover
• Garden value: pollinator friendly and pleasingly low-fuss

Allium schubertii ‘Arctic Snow’ is an allium of real theatre: airy, starry white florets arranged in an architectural, firework-like sphere. Rising on sturdy stems above bright green foliage, it brings a crisp, contemporary note to borders, gravel gardens and smart container displays — and it is equally poised in a vase, fresh or dried.

Plant in autumn and allow it to settle quietly through winter; come late spring it provides a sculptural highlight that looks particularly refined threaded through ornamental grasses and soft, billowing perennials.

• Colour & form: White, star-shaped umbels with a distinctive ‘firework’ silhouette
• Garden uses: Borders & beds, containers, gravel gardens; excellent cut and dried stems
