Allium

Architectural form and bee magnet
Allium is a decorative ornamental onion that forms striking balls of star-shaped flowers on tall, sturdy stems. Its sculptural form and long-lasting flowering make Allium a popular choice in modern gardens and as a cut flower. The plant attracts bees and butterflies and combines well with perennials. Suitable for spring planting and extremely winter-hardy.
Allium – structure and elegance in one flower
Allium, also known as ornamental onion, is a striking spring bloomer with spherical flower heads consisting of dozens of small star-shaped flowers. These unique flowers appear on long, upright stems and add architectural value to any garden or border. The most popular varieties, such as Allium ‘Purple Sensation’, ‘Globemaster’ and ‘Mount Everest’, are real eye-catchers due to their size and intensity of colour.
Allium usually blooms in late spring to early summer and provides a perfect transition between spring and summer flowers. Alliums are also very attractive to pollinators such as bees and butterflies and are an excellent choice for natural gardens or bee-friendly borders. The flowers are also popular as dried flowers.
Application:
Gardens with a modern or natural look
Cut flowers and dried flowers
Combination with perennials such as salvia, geranium and ornamental grasses
Suitable for parks, public gardens and landscape design
