This hardy bulb flowers in late spring to early summer with two flower spikes of airy, 2-inch umbels of golden-yellow florets. It blooms about two weeks earlier than the straight species. It prefers average, well-drained soil in full sun. Alliums are deer resistant and are a perfect companion to interplant with tulips and crocus to deter squirrels and chipmunks from digging up the bulbs.
