Flowers classified as annuals have particular life cycles for when they will bloom and die. Knowing when a flower will bloom aids you in knowing the best time to plant particular flowers.
Definition of Annuals
In general, a flower classified as an annual completes its life cycle of growing, flowering, and setting seed all in one year. The flower then dies.
Types of Annuals
Annuals are further categorized according to the weather and soil conditions that they flourish in. Hardy annuals are more tolerant of frost but usually die when summer heat arrives because they cannot tolerate hot weather. On the other hand, tender annuals cannot tolerate the frost of winter weather or cold soil temperatures. In between the two are half-hardy annuals, which cannot withstand winter's harsh cold and may also die in the heat of summer.
When to Plant
An annual's bloom time determines when it should be planted. Annuals that flower during the summer and fall, and die with the first frost, are planted in the spring after the threat of frost has passed. Annuals that will flower in the winter and spring, then die in the summer, are planted in the fall.
