A very delicate and pretty, early-flowering, pure white allium, cowanii is excellent in the border and as a very long-lasting (3 weeks) cut flower. You can eat the flowers in salad too.
Allium petals are edible, you can scatter them on salads. We use the more delicate types like cowanii and unifolium most often at Perch Hill.
Removing the foliage once it becomes tatty doesn't appear to affect the bulbs.
