Bulbs generally fall into two main categories – spring flowering bulbs and summer flowering bulbs.
Spring flowering bulbs are hardy bulbs and often serve as a first sign of spring when they bloom. They are planted before fall’s first frost and are able to withstand the cold winter months. Most spring flowering bulbs, like daffodils, are able to flower year after year without being replanted.
Summer flowering bulbs are planted after the season’s last frost because they are not able to survive cold and harsh winter conditions. These bulbs, too, can flower year after year, but only if cared for properly. They must be dug up after flowering and becoming dormant, stored indoors over winter and then replanted after the next year’s final frost to be viable.
Spring flowering bulbs include daffodils, tulips, and hyacinths, while summer flowering bulbs include gladiolus, dahlia and canna.
