Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses

Edible Parts: Fruit
Edible Uses: Drink

Fruit - ground up and mixed with clay[161] ( the clay probably has a neutralizing effect on the toxins). A very toxic plant, its use cannot be recommended. The fruit is about 7cm long and 6cm wide[200]. A stupefying beverage is made from the leaves and roots[161].

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.
Narcotic

The whole plant is narcotic[200]. It has been used in the past to deaden pain, treat insomnia etc, but any use of this plant should only be carried out under the supervision of a qualified practitioner since the difference between the medicinal dose and a toxic dose is very small.

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

This species is extremely susceptible to the various viruses that afflict the potato family (Solanaceae), it can act as a centre of infection so should not be grown near potatoes or tomatoes[200].

Propagation

Sow the seed in individual pots in early spring in a greenhouse[200]. Put 3 or 4 seeds in each pot and thin if necessary to the best plant. The seed usually germinates in 3 - 6 weeks at 15°c. Plant out in late spring or early summer, after the last expected frosts. Especially in areas with hot summers, it is worthwhile trying a sowing outdoors in situ in mid to late spring.
