Best Management Practices - Annual Flowers

Allen D. Owings, Trawick, Robert C., Bush, Edward W.

More than 80 percent of bedding plants sold for landscape use in Louisiana are classified as warm season annuals. Major warm season bedding plants include ageratum, begonias, cockscomb (celosia), coleus, impatiens, marigolds, periwinkle (vinca), petunia, portulaca, purslane, salvia and zinnia. Some other warm season bedding plants, such as sunflowers, torenia (wishbone flower), geraniums, gomphrena and melampodium are available, too.

Pansies dominate the cool-season bedding plant market in Louisiana. Other major cool season bedding plants include dianthus, snapdragons, viola and ornamental kale/cabbage. Alyssum and stock are two cool-season bedding plants growing in popularity.

Probably the key Best Management Practice for annual flowers in Louisiana is the proper use based on the purpose and site location.
