Pre-treatment: None required

Establishment: Seeds are collected from whole fruits immediately prior to or after ripening. If capsules have not opened, they may need to be mechanically split. Large numbers of dry fruits may be shattered rapidly by very brief blending. After blending, seeds may be cleaned by sifting and/or blowing off chaff.
