Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Cosmos is a colorful annual with bright, daisy-like flowers a variety of pink and lavender shades, as well as white and yellow. Some forms are simple, single petaled, while some have double petals or tube-like petals. Depending on the cultivar, they grow about 2 to 3 feet tall and half as wide. Deadheading will encourage more blooms; but cutting them early for vases is better still. Foliage is ferny and is great for filling in voids in the garden. Cosmos will self-sow if happy with its location. It prefers full sun and well-draining soil.
