Mutant flowers

Asked July 26, 2020, 11:32 AM EDT

why do I have these mutant flowers where several are merged together? I have it with these sunflowers as well as zinnias. Is it that the pollination is the problem?

Hi - This type of unusual growth sometimes occurs in flowers (and other plant parts) when there is a mistake at the cellular level during tissue development. The symptom is referred to as fasciation can be brought about by genetic, hormonal, bacterial, fungal, viral, or environmental causes. The following articles provide further information on why these interesting mutations occur.
