Wildflowers of the Adirondacks:
Dewdrop (Dalibarda repens)
Dewdrop (Dalibarda repens) is a native wildflower with rounded, heart-shaped leaves and small white flowers that appear in summer. It grows in moist forests in the Adirondack Mountains of upstate New York.
A member of the rose family, this plant is also known as False Violet, Robin Runaway, Robin-run-away, and Star Violet. The name False Violet comes from its heart-shaped leaves and the fact that this species, like violets, produces two kinds of flowers. No information was found on the origin of the common names Robin Runaway or Dewdrop.
Dewdrop is listed as endangered in Connecticut, New Jersey, North Carolina, and Rhode Island, and threatened in Michigan and Ohio.
Identification of Dewdrop
Dewdrop is a low-growing plant, growing less than 6" tall. The creeping stems are often shallowly buried.
Dewdrop leaves are dark green and heart-shaped at the base. The leaves are slightly hairy. They are long-stalked and are up to two inches long and wide. The margins of Dewdrop leaves are scalloped, with low, rounded teeth.
Dewdrop produces two types of flowers. The ones we observe along the trail are open, white flowers, generally about half an inch wide, with five petals and numerous slender stamens. These flowers appear singly on a reddish, leafless stalk. The second type of flower is fertile. It lacks petals and is hidden beneath the leaves.
Dewdrop is one of the few shade-tolerant woodland ground cover species which flowers in summer. It usually begins blooming in late June or early July and continues blooming through late August.
Uses of Dewdrop
Dewdrop has very limited human uses. The only medicinal use found was by the Iroquois, who are said to have used a decoction of powered plants as a blood purifier and a treatment for venereal disease.
Wildlife Value of Dewdrop
This species has no reported value as a wildlife food or cover.
Distribution of Dewdrop
Dewdrop's range includes Ontario east to Nova Scotia, south to North Carolina, and northwest to Ohio, Michigan and Minnesota.
In New York State, Dewdrop may be found in most counties in the northeastern part of the state. In the Adirondack Park, Dewdrop occurs in all counties within the Blue Line, except Clinton, Herkimer, and Warren counties.
Habitat of Dewdrop
Dewdrops are shade-tolerant. They can grow in shade and part-shade, on well- to poorly drained sites, often under conifers. This species can be found in cool, moist hardwood and coniferous forests, mixed woods forests, and on hummocks in forested swamps and boggy areas.
In the Adirondack Park, Dewdrop is found in several ecological communities, including:
