6-29 Double flowered Chokeberry
6-29
A normal Chokeberry flower has one whorl of 5 petals. These have two complete whorls of petals, 10 in total. Such mutations can be a first step in speciation. If the extra petals confer an advantage, or at least no disadvantage, they may persist and double-flowered chokeberries might become a scientifically recognized species. If they are a disadvantage the plant will be a dead end, a failed experiment.
