Uses

Toxicity

Toxicity warning. The historical record reports a hazard for this plant. Do not use it to decide which parts are safe to eat or use medicinally.

Regular ingestion of large quantities of these plants can be dangerous due to their high mineral content[3]. This report, which seems nonsensical, might refer to calcium oxalate. This mineral is found in I. capensis and so is probably also in other members of the genus. It can be harmful raw but is destroyed by thoroughly cooking or drying the plant[K]. People with a tendency to rheumatism, arthritis, gout, kidney stones and hyperacidity should take especial caution if including this plant in their diet[6].

Edible uses

Young shoots - cooked[2][4]. Some caution is advised, see the notes above on toxicity.

Propagation

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.

Cultivation

We have very little information on this species but, judging by its native range, it should be hardy in Britain. The following notes are based on the general needs of the genus. Succeeds in any reasonably good soil[1]. Grows well in heavy clay soils. Prefers a moist well-drained humus rich soil in a cool site[5]. 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[K].
