Solanum laciniatum
Safety & Hazards
All green parts of the plant, and the unripe fruits, are poisonous[1, 2]. Although providing many well-known foods for people, including the potato, tomato, pepper and aubergine, most species in this genus also contain toxic alkaloids. Whilst these alkaloids can make the plant useful in treaing a range of medical conditions, they can also cause problems such as nausea, vomiting, salivation, drowsiness, abdominal pain, diarrhoea, weakness and respiratory depression[3]. Unless there are specific entries with information on edible uses, it would be unwise to ingest any part of this plant[PFAF].
Cultivation Details
Tolerates temperatures down to at least -7°c in Australian gardens[4] but is not very hardy in Britain. It sometimes succeeds as a shrub outdoors in the mildest areas of the country[5] but is more usually cut to the ground by winter cold. It can, however, be grown at the foot of a warm sunny wall and be treated as a herbaceous perennial. As long as the roots are given a good mulch in autumn they should survive quite cold winters[6, 5]. Succeeds in most fertile soils in a sunny position[7]. Alternatively, it is possible to grow the plant as an annual. If the seed is sown in early spring in a warm greenhouse and planted out after the last frosts it can fruit in its first year though yields will be lower than from plants grown as perennials[PFAF]. There is much confusion between this species and Solanum aviculare. Some botanists unite the two under Solanum aviculare whilst others say that Solanum laciniatum is a tetraploid form of that species[8]. Solanum laciniatum is treated as a distinct species here[PFAF].
Propagation
Seed - sow spring in a warm greenhouse. Germinates in 2 - 3 weeks at 20°c. Prick out the seedlings into individual pots when they are large enough to handle. If growing the plants as annuals, plant them out after the last expected frosts and give them some protection such as a cloche until they are growing well. If growing as a perennial, especially in areas at the limits of its cold-hardiness, it will probably be better to grow the plants on in the greenhouse for their first winter. Give them fairly large pots (12cm or larger) because they have very strong root growth. Top growth might die back over winter, but the roots should survive if temperatures in the greenhouse do not fall below about -5°c. Plant them out in early summer of the following year. The plants will be somewhat hardier in their second winter. Cuttings of half-ripe wood, mid summer in a frame. Very easy, the cuttings root within a couple of weeks. Pot them up in fairly large pots and overwinter them in the greenhouse before planting out in early summer.
