Nigrum Allium blooms reach 20-24" in height. The bloom size is up to 2-4". The white blossoms can be paired with so many other perennial options for late spring.
They are a cost effective alternate to Giant Alliums. When massed together they give a whimsical and wonderful effect in the gardens and for your flower arrangements. Allium bulbs are splendid for naturalizing if planted in rich, well-drained soil.
