About
Silene undulata (Xhosa: iindlela zimhlophe—"white ways/paths", also known as Silene capensis, and African dream root) is a plant native to the Eastern Cape of South Africa.
How to grow it
In cultivation, S. undulata is an easily grown, but moisture hungry herb. It is tolerant of extreme heat, >40 °C (104 °F), and moderate cold, −5 °C (23 °F). 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.
