Notes
Cosmos (Cosmos bipinnatus) is an annual for borders, cottage gardens, and mass plantings. Frost will kill it, so set it out only after the last frost in spring. This plant likes full sun and dry to average soil. It grows 12 to 48 inches tall and spreads 24 to 36 inches wide. Give it room so the plants can fill in.
Pairs well with Spider flower, Hollyhock, and Red fescue.
