Cosmos bipinnatus 'Rubenza'
Asteraceae Cosmea

Our 2010 Flower of the Year. Wonderfully easy-to-grow plants which flower all summer until the first frosts. The dark, ruby-red blooms change to a lovely traditional rose red as they mature—their outstanding color has earned them a Fleuroselect Novelty award. This variety shows excellent garden performance, especially planted in borders in drifts. Germination: 7-14 days, 65- 85F. Well-drained soil. 36in.
