There are as many types of lilies on the market today as there are people who love them. Choosing lily bulbs for sale in spring ensures a summer filled with exotic blooms and hardy plants. They are best viewed in sunny sites like along a pathway or near an entry. Some lily flowers are fragrant, making them a great cut flower. Lily bulbs can be divided or transplanted in the fall after all the blooms are spent and foliage has wilted.
