Epilobium ciliatum

There are two subspecies of Common Willow-herb at the Park. They differ in leaf shape, petal length, and whether there are turions (a small bud, capable of growing into a plant)present. Both are plants of moist habitat. This is subspecies glandulosum in which the pink petals are as much as a half-inch in length.
