Edible Uses
Edible Parts: Fruit.
Edible Uses:

Fruit - raw or used as a beverage[11, 46, 61, 105, 153]. The pressed fruit is drunk raw or fermented into a wine[2]. Use with great caution since most parts of the plant, including the seed[173], are very toxic and some reports suggest the fruit should not be used at all[11].
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.



None known
Other Uses
Dye.

A black ink is obtained from the leaves, it can also be used as a dye[46, 139, 153]. The bark can also be used, it is rich in tannin.
Cultivation details
Prefers a fairly good loamy soil in a sunny sheltered position[11, 164, 200. Succeeds in light shade[200]. This species is not very hardy in Britain, it tolerates temperatures down to about -5°c and succeeds outdoors from Sussex and westwards[200]. There is some confusion over the name of this species, some botanists unite this species with the S. American C. ruscifolia whilst others maintain that they are distinct[11, 200]. The roots of plants in this genus bear nitrogen-fixing nodules[218]. Whilst much of the nitrogen will be utilized by the growing plant, some of it will become available for other plants growing nearby[K].
Propagation
Seed - sow February/March in a greenhouse[78]. The seed usually germinates in 1 - 3 months at 15°c[164]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7cm with a heel, July/August in a frame. Fair percentage[78].

The treatment for Tutu poisoning is barbituates(p.56 H.E. Conner.The Poisonous Plants in New Zealand).

The toxin in Tutu can end up in honey if the insect known as Passionvine Hopper has been sucking on the sap leaving honey dew eaten by bees, this is rare in New Zealand but something to think about when considering planting it.
