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].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

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).

dn   Tue Dec 23 2008

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.
