An annual is a plant that completes its entire cycle in one growing season. Many plants that are considered annuals in the north can survive for years in Florida and thus are perennials. Perennials are plants that live at least 3 years under local conditions. The plants grown as annuals in the USA come from all over the world. A few favorites include ageratum , zinnia and marigold from Mexico, petunia and verbena from Argentina, four o'clocks from Peru and California Poppy and phlox from North America.
Annuals are bright and cheery additions to any garden and can be used in many landscape situations.
The splash of bright color makes an excellent focal point. When annuals are planted in containers, either stationary or hanging from trees or eaves they add color to accentuate the surrounding area. Zinnias, marigolds and petunias are the most popular annuals. All of them are sun lovers and provide a massive display of color. The colors available seem limitless.
