The heading denotes those plants planted in the spring, dug in the fall, and stored over winter. Also included are plants not dug in the fall but bloom in the summer.
Summer flowering bulbs have varied uses.
They can fill in bare spots where larger plants are needed. The larger flowering bulbs can be used as temporary screens. Some can be used in shade but most prefer full sun. They are best in mass plantings but the digging and planting of such a bed can be a lot of work. Don't buy bulbs showing signs of rot or disease.
