The flowers bloom on tall, sturdy stems that can reach up to 30-50cm in height, making them perfect for adding vertical interest to the garden.

Aside from its striking blooms, the Allium Millenium also boasts attractive foliage. Its long and slender leaves are a deep green colour and have a glossy texture, providing a beautiful contrast to the colourful flowers.

This perennial plant is known for its long blooming period, typically from July to August. It also attracts pollinators such as bees and butterflies, making it not only visually appealing but also beneficial to the ecosystem.

Allium Millenium is a low-maintenance plant, making it suitable for both beginner and experienced gardeners. It thrives in full sun to partial shade and prefers well-draining soil. Once established, it is drought-tolerant and can withstand occasional periods of neglect.

How to plant and care for your Allium bulbs

Plant your Allium bulbs in autumn, between October and December. Alliums do not like heavy wet soil, but they want to be moist but free draining. Add grit if you think your soil is too heavy. They do like to be in a sunny position. Planting 5cm deep will help keep the flower stable.

Alliums are hardy and will flower perennially. You don’t need to lift them although it is good to check on the size of the bulbs during autumn. You can leave in the larger bulbs and take out the small bulblets. This will prevent them getting too crowded.

Alliums originated in mountainous regions of Asia. This is why they like hot summers, cold winters and free draining soil.
