About plant names...

Spreading dogbane is related to milkweeds and, like milkweeds, exudes a milky sap when leaves and stems are broken. The foreboding name dogbane comes from its strong toxicity, to people as well as dogs. Dogbane is a North America native plant.

Identification: Plants are shrubby, up to 4' (1.2 m) in height. Stems are branching, smooth or slightly hairy, round, light green, dark red, or purple. Leaves are opposite, roughly oval-shaped, with pointed tips and smooth edges, green on top and pale green below. Flowers are white to pink or with pink interiors, about ¼" (6.3 mm) around, tubular to bell-shaped, with five flared petals. They are fragrant and occur in clusters at the tips of branches. They remind me a little of blueberry flowers.

Edibility: Poisonous Skull & Crossbones Potent, intensely bitter alkaloids apocynamarin or cymarin depress heart rate and act on the vaso-motor system.
