The blooms are just soooo... beautiful! I can not get enough of these blooms! They are one of the few vars. that do not have stem rot, the main cause of death in Cosmos. The blooms are abnormally large for the species, 4".Their only problem is that they do not start blooming for 80 days. But will always be growing this plant!
