Allium giganteum

Giganteum means Giant. Allium giganteum is exactly that. Giant globes of purple flowers, I came across one day, walking down on the banks of the River Thames. They are eye-catching. Allium giganteum is also called the Giant Onion or Giant Allium. It is a bulbous herbaceous perennial and is an ornamental onion plant. It is part of the Amaryllidaceae family of plants.

The leaves usually die down before the flowers. Either way, the leaves are at a much smaller scale than the giant flowers. Allium giganteum is native to Asia and North-East Iran. It flowers in late spring or summer. The flowers are little star-shaped lilac flowers formed in a cluster depicting a globe. The blooms are long-lasting and colorful and look nice both in the garden as well as in flower arrangements.

About Online Flower Garden & Dino

I am a flower enthusiast and a gardener at heart. Ever since childhood I loved reading about plants and started gardening at an early age. First by helping my father in the garden and later managing a large garden myself in my teen years. I planted and cared for a large number of plants, flowers, and trees both outdoors and in a greenhouse. To this day I enjoy visiting gardens and parks and learning about new and old specimens and varieties of plants.
