Is it ok for coleus plants to flower, or is it that mine are going to seed?

Over the years, hybridizers have simply been crossing the top-perfoming coleuses together and keeping the best for further breeding. Genes for self-branching and also delayed flowering have become the norm.
Thus, you no longer have to pinch or prune most modern coleuses: they grow perfectly without your help.
Some varieties are not as “advanced” as others and begin to bloom early, in August or even July.
Pinching off coleus flowers is a snap: just squeeze the spike between the thumb and forefinger until it comes free. Or cut it off with pruning shears. It only takes a second.
