Fragaria × Comarum hybrids

There are several commercially important hybrids between Fragaria and Comarum species in existence, but they have not yet received formal botanical names as hybrids between those genera. Both Fragaria and Comarum have at different times been considered to be part of the genus Potentilla, and these hybrids have been named Potentilla x rosea, or are sometimes referred to as Fragaria × Potentilla hybrids.

The first-generation hybrids have been recorded as heptaploid, i.e. with seven sets of chromosomes; four sets of chromosomes came from their octaploid strawberry parent, and three from their hexaploid Comarum parent.

All commercial cultivars resemble strawberries more closely than they do Comarum. They are all vigorous, and produce runners profusely.
