[Wikipedia] Seed Information: Seeds are tiny and bumpy, in a rounded pod 1–3 cm (0.39–1.18 in) long, tapering to a point at both ends. They lack the elaiosomes present in many other members of the family. They do not easily germinate without being exposed to smoke. In cultivation, a liquid smoke extract is often used.
