About Cosmos

Cosmos are delicate, airy flowers that bloom prolifically through summer and monsoon. Standard types grow dangerously tall and floppy. For terrace gardeners, selecting a dwarf, early-blooming variety ensures a compact, self-supporting burst of color that won't require heavy bamboo trellising.
