This plant has seed capsules that spring open forcibly as the seed ripens to eject the seed a considerable distance. The capsules are sensitive to touch even before the seed is ripe, making seed collection difficult but fun[

Seed - raw[
]. No more details are given, but the seeds are difficult to harvest in quantity. This is mainly because of their exploding seed capsules which scatter the ripe seed at the slightest touch[
An edible oil is obtained from the seed[
Ripe fruits - raw[
]. A confusing report, the plant produces a capsule surrounding the seeds[
Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
