Flowers: White, 1/8"-1/4", with five-lobed corolla and five sepals. Interior of flower contains a raised, five-lobed structure typical of milkweed relatives. Flowers in a rounded cymose cluster.
Leaves: Opposite, entire, ovate to lanceolate, 2"-4", often with reddish or pinkish veins continuing from the red stems of the plant. Veins exude a milky juice when broken.

Comments: A relative of the milkweeds, this native plant is also known as Hemp Dogbane. All parts of the plant contain a cardiac poison, and the milky sap can be irritating to the skin. The stems contain strong fibers that can be extracted and made into cordage; this use is the source of the common name.

Where to find it: There is a large patch to the east of the pond beyond the trail.
