Answer: Alliums are considered hardy bulbs and can be left in the ground all year around. They are generally planted in the fall, but you can plant yours now. Set them 3" deep and about 6" apart (groups look better than single plants). After blooming the foliage should be left to grow and mature and eventually fade. Once it has browned it may be cut off at ground level. The flowers may be removed when they fade. Removing the blooms prevents the bulb from using energy to set seed, which allows it to retain stored energy for larger bulbs and more foliage and flowers the next year. Enjoy!
