There are more than 500 species of allium, and many of the varieties grow best in direct sun. A. caeruleum and A. sphaerocephalum are two members of a group of allium that is exceptionally drought resistant and at the peak of growth during the hottest summer months. These varieties have foliage in shades of purple, pink and yellow. During the time when these types of allium bloom, the leaves die away, leaving only the stem and a colorful bloom. No matter which cultivar of allium you choose, they typically share the same general care requirements. Plant allium in a sunny, well-drained area. If you are planting in a pot or other container, use a deep container and remember to repot and add fresh compost each year. When the plant is finished blooming for the season and the leaves turn yellow, cut the plant down to ground level. Allium is a bulb plant and will come back each year on its own.
