Favorite or New Plant

Few annual plants are as colorful and easy to grow as cosmos (Cosmos bipinnatus and C. sulphureus). They come in several colors including pink, orange, burgundy, and white. Their flowers are held high on erect stems above fern-like foliage. Cosmos make excellent cut flowers and add a casual look as a background plant or part of a border. Plant them in spring after the soil has warmed to the touch or start early indoors 4-6 weeks before setting out. Cosmos requires full sun, moderate water, and is not fussy about soil as long as it's well-drained. When the plants begin producing flowers, dead head frequently to keep them looking tidy.
