Annuals are flowers that bloom the first year they are planted, often flowering just a couple of months after sowing. Most annuals are started indoors or in greenhouses in late winter or early spring.

Designing with annuals gives lots of importance to flower color. Annuals offer flower color for a longer period of time than other plant types, for they are constantly in bloom. Blue to purple annual flowers, such as sweet alyssum and heliotrope, are often used in complex plans.
