Notes
'Rosetta' cosmos (Cosmos bipinnatus 'Rosetta') is an annual for borders, cut flowers, pollinator gardens, and containers. It cannot take cold, and a freeze will end its season. This plant likes full or part sun and dry to moist soil of most types. It grows fast and forms a clump, and it is drought tolerant. Butterflies, hummingbirds, bees, and birds visit it. Deer rarely make it their first choice.
Pairs well with Purple top, Silver feather grass, and Ageratum.
