Add Striking Vertical Colour with Allium Sphaerocephalon Bulbs

Allium sphaerocephalon, also known as the Drumstick Allium, is a hardy perennial bulb prized for its unique oval flower heads that emerge in early to mid-summer. Each stem rises up to 90 cm (36") tall, topped by a compact cluster of purple-green florets that gradually deepen in colour as they mature. These architectural blooms stand out in any border or naturalistic planting, drawing the eye and adding movement among swaying grasses.

Why Choose Drumstick Alliums?

• Easy to Grow: Plant bulbs in autumn or early spring in well-drained soil. Once established, they require little maintenance and are drought tolerant.
• Bee Magnet: The nectar-rich flowers attract bees and other pollinators, supporting local biodiversity.
• Dramatic Group Planting: For best effect, plant bulbs in clusters of at least five or more. Their slender stems look stunning when woven through borders or gravel gardens.
• Tall & Elegant: Reaching up to 90 cm high with an 8 cm spread, these alliums add height and texture without crowding neighbouring plants.
• Versatile Placement: Ideal companions include ornamental grasses, perennial geraniums, and other sun-loving perennials.

Planting & Care Guide

• When to Plant: Best planted from September to November or early spring before growth starts.
• Where to Plant: Choose a sunny position with well-drained soil. Avoid waterlogged areas as bulbs dislike wet feet.
• Caring for Your Alliums: Little maintenance needed; allow foliage to die back naturally after flowering to feed next year's growth. Deadhead spent blooms if you wish to prevent self-seeding.
• Hardiness: Fully hardy throughout the UK (RHS H5), suitable for most gardens.

Add Colour, Texture & Wildlife Appeal

The compact size and upright habit make Drumstick Alliums perfect for mixed borders, prairie-style schemes, or contemporary gravel gardens. Their long-lasting flowers also work beautifully as fresh or dried cut flowers indoors.
