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. Multicolor annual flowers bring a splash of color to your garden.
Some annuals, called tender annuals, are killed by frost. They grow in hot weather and are started indoors or in greenhouses and then set out in the garden after the danger of frost passes. Some of the faster-growing mulitcolor tender annuals, such as zinnias, can be sown directly into garden beds -- after the frost in spring -- for bloom or use all summer long. This depends on many factors, including where you live and how long summer weather lasts.
These annuals have some built-in frost tolerance. They are often, but not always, planted outside from seed a few weeks before the final frost, but sometimes they are started indoors in warmer conditions, hardened off for a good adjustment, and planted outside during spring (or in winter in Zones 8 to 10).
On this page, we've included links to multicolor annuals, grouped according to light condition. Before planting, check with your garden center to make sure that the annuals you've selected will flourish in your locale.
