Why we grow it

Mixed garden cosmos brings a loose, colorful look to a sunny flower bed. Pinch young plants for more branching, then keep clipping old blooms to encourage new ones.

Direct sow after frost when soil is warm enough, or start the seeds indoors before planting out. Taller types may need a support when they stretch.
