Dogbane is a perennial shrub that is native to and common in North America. Dogbane bark is a superb source of fiber
for making clothes, twine, nets, bags, etc. The plants are harvested in the fall, after the toxins drain
to the roots.
Plants: 6½–20′ (2–6 m) high, with reddish stems that
excude a milky latex if cut. This sap can cause blisters. Stems are woody at the base,
branching a lot further up.
Leaves: Opposite, simple, entire, broadly lanceolate, 2½–6 ⨉ 1–1¾″ (7–15 ⨉ 3–5 cm). Leaves are smooth on top and have fine white hairs below.
Flowers: White to greenish-white flowers have large sepals and a five-lobed corolla.
Each flower is ¼″ (6.3 mm) in size. They appear at leaf tips or leaf axils.
They appear from May to August.
Fruits: Flowers are replaced by pairs of narrow pointed pods about 4–5 ⨉ ⅛″ (10–12 cm ⨉ 3.2 mm). Each pod contains a large number of seeds, and has tufts of silky white hairs at its tips.
Habitats: Woods, ditches, and hillsides, in gravelly or sandy soil.
Edibility: Poisonous This is poisonous to dogs and livestock
as well as to people, and can cause heart attack. Stems contain a milky sap that causes skin to blister.
The “cannabinum” in the scientific name refers to a
similarity to Cannabis, because of the fibrous properties of both plants. Dogbane is not psychoactive.
Despite the plant’s toxicity, seeds can be ground to produce a meal.
Medical: Native Americans used this plant for a variety of
medical treatments, though its high degree of toxicity requires a great deal of expertise.
