Product Description

These incredible Allium Sphaerocephalon (drumsticks) are a real must-have for any garden! These unique flowers open green, then start to turn a purple/crimson colour from the top, creating unusual two-tone drumstick flower heads. Their attractive curled green leaves will wither before the flowers appear in early summer so we recommend accompanying them with low-growing perennials to provide filling foliage over the base areas. Perfect for garden borders or even patio containers, the Allium will reach a height of 60cm. Preferring direct or partial sunlight they also look great as part of a cut flower display for within the home. Flower between May to June. 5cm+ bulbs supplied.

Growing at a glance…

Plant in fertile, well-drained soil at approx 10cm apart and at a depth of roughly 3-4 times the size of the bulb. Larger bulbs should be spaced 20cm apart. Leave untouched for a number of years until the bulbs have multiplied and divide if necessary. Smaller alliums can be grown in containers, but ensure it's large enough to space the bulbs an appropriate distance apart.
