Cosmos bipinnatus · Annual
Cosmos is grown as an annual, that matures to about 1–4 ft × 2–3 ft. It does best in full sun with medium water needs in well-drained and occasionally-dry soil. Expect yellow, pink and purple blooms in summer. It attracts bees, butterflies and pollinators, stands up well to deer, drought and dry soil and grows happily in containers.
