include tender bulbs (which cannot survive cold temperatures) such as begonias
. They also include some hardy bulbs (which require a period of cold to bloom) such as lilies
. Summer-flowering bulbs
are planted in late spring, when there is no longer a chance of ground frost, and will flower a couple of months later. They will bloom in most climates but are not generally winter hardy. This means most summer-flowering bulbs
should be lifted in the fall following the first frost that discolours the foliage and stored until used during the next season.
