Cosmos, Double Click Rose Bonbon

Double Click Rose Bon Bon Cosmos is the first separate colour for a fully double Cosmos bipinnatus. This variety will add height and interest to the border with the blooms reaching an approximate height of between 60-90cm (24-36″). Is the flower cosmos a perennial? Nearly all cosmos are annuals meaning they do not come back every year. In order to have blooms every year, you will need to resow the seeds the following spring. The only exception to this rule is chocolate cosmos, cosmos atrosanguineus, which is grown like a dahlia from a tuber and is a perennial.
