Purple Milkweed.Asclepias purpurascens.
Found along dry roadsides in July.
The generally single stalk varies from 1 to 3 feet in height, is tough-fibred, slightly grooved, and a trifle downy to the touch; it is very milky. The color is light green, crimson at the joints.
The long, oval leaf is sharp-pointed at the tip and blunt at the base; its midrib is very flat on the top but round beneath, and the cross-veins show plainly; the margin is entire, the edge curling under, and the upper surface is smooth while the underside is velvety; the color is yellow-green, with a crimson midrib that is purple underneath. The leaves, on short, thick purple stems, are placed in pairs, at alternate angles with one another.
The tubes belonging to the crown of this rather large flower are long and oval in shape, their horns being short and broad with suddenly-straight tips; the lobes are long, oval, and widely flaring; all these parts are colored a strong, dark glowing crimson. The flowers are set on foot-stems that are twice their own length, and pale green in color; they are arranged in a loose cluster upon a short, stout purplish stem, and grow terminally, and from the angles of the upper leaves.
This plant is inappropriately designatedpurpurascens, since its full and beautiful crimson flowers are unusually pure in tone.
