Yellow Cosmos Overview

This species is a fast growing upright bushy hardy annual from Mexico. It is drought tolerant once established. The medium green leaves are feathery and wide; they will provide a back drop for the clusters of flowers which are white-green, pink, orange-red and will bloom from summer into the autumn. They will prefer a soil that is not too rich as that will produce rather lanky and tall specimens.
