Appearance

Habitat
The plant is predisposed to moist and rich soil, but can be found growing in a wide array of soil types. It is naturalized throughout warm temperate and subtropical regions of the world. Although it is often considered a noxious weed, "Ipomoea purpurea" is also grown for its beautiful purple and white flowers and has many cultivars. Common cultivars include "I. purpurea" 'Crimson Rambler'; 'Grandpa Ott's,' 'Kniola's Black Knight,' and 'Star of Yelta'; and 'Milky Way'.The triangular seeds have some history of use as a psychedelic; they, like "Ipomoea tricolor" contain LSA. Effects are reported to be somewhat similar to those of LSD.
