This small-scale Allium is perfect tucked along the front of the border. Narrow glaucous blue-green foliage forms a tidy habit until numerous clusters of lavender purple flowers spring up in midsummer, persisting for many weeks. Attractive seedheads remain after flowering has finished. Compared to 'Blue Eddy', 'Pincushion' is far more floriferous but lacks twisting and curling on the leaves and stems.
Alliums are charming plants for the rock or herb garden. When the foliage is bruised, it smells like onions since they are in the onion family. Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.
