Silene undulata (—"white ways/paths", also known as Silene capensis, and African dream root) is a plant native to the Eastern Cape of South Africa.

Cultivation

In cultivation, S. undulata is an easily grown, but moisture hungry herb. It is tolerant of extreme heat, >40 C, and moderate cold, -5 C. A moisture retentive seedbed is essential. The fragrant flowers open at night and close in the day. It is a biennial to short lived perennial and the root can be harvested after the second year.

Uses

Silene undulata is regarded by the Xhosa people as a sacred plant. Its root is traditionally used to induce vivid (and according to the Xhosa, prophetic) lucid dreams during the initiation process of traditional healers, classifying it a naturally occurring oneirogen similar to the more well-known dream herb Calea zacatechichi.
