swallowwort (Asclepias), a genus of mainly herbaceous plants of the family Asclepiadaceae. There are over 100 species in America and several in Africa. The best known is the Syrian milkweed, or Aescupapius’ herb (A. syriaca), a perennial native to America. It is cultivated and readily becomes wild. In the USSR the milkweed that has grown wild is found in the Baltic areas, Byelorussia, the Ukraine, and the Caucasus.
Milkweed is a tall plant (up to 2 m) with compact, for the most part elongated-elliptical, leaves. Its lilac reddish, small, fragrant flowers are gathered into umbellate inflorescences. Fruit grows in the form of follicles. White, silky floss on the seeds facilitates their distribution by wind. The milky sap contains tar and rubber components; the seeds contain more than 20 percent semisiccative oils, suitable for technical purposes. A sturdy fiber is obtained from the stalk for manufacture of coarse fabrics and ropes. Syrian milkweed is a drought-resistant, nectariferous plant, unfastidious in cultivation. This species and other species of milkweed are sometimes grown as decorative plants.
