ALLIUM SEEDS

The Allium genus, a prominent member of the Amaryllidaceae family, is celebrated for its ornamental and culinary value. Known commonly as Ornamental Onions, Allium species are recognised for their striking globe-shaped flower heads and their ability to add architectural interest to gardens. These blooms, often in shades of purple, pink, white, or yellow, are long-lasting and attract pollinators like bees and butterflies.

Native to temperate regions of the Northern Hemisphere, Allium thrives in well-drained soils and sunny locations. These hardy perennials are drought-tolerant and ideal for borders, rock gardens, or naturalistic plantings. Among its many species, Allium giganteum stands out with its towering stems and large, spherical flower clusters, making it a favourite for dramatic garden displays.

The Allium genus is also well-known for its edible varieties, including onions, garlic, and leeks, which have been cultivated for centuries. Combining bold ornamental appeal with practical uses, Allium remains a versatile and essential genus for gardeners and culinary enthusiasts alike.
