Senecio scandens
Safety & Hazards
Senecio scandens is a commonly used medicinal herb, especially in China, where it is a component of more than 100 compound herbal medicines. However, the plant is known to contain pyrrolizidine alkaloids. These alkaloids, which are derived from various amino acids including ornithine, have a range of antinutritional activities. In particular, they can have a pronounced hepatic toxicity, though the lungs and other organs may be affected as well; mutagenic and carcinogenic activities have also been reported[1, 2]. The alkaloids have a cumulative effect upon the body and, unless concentrations in a plant are high, occasional use is generally safe and in the case of medicinal herbs, can be very beneficial. In general it is best to seek advice before medicinal use.
Cultivation Details
Senecio scandens is a plant of warm temperate to tropical areas. It is unable to tolerate much frost[3]. It succeeds outdoors in the milder areas of the temperate zone, where it needs to be grown against a sunny sheltered wall[4]. Succeeds in a sunny position in most well-drained moderately fertile soils[3]. Plants can be cut back to the ground in cold winters, though they usually resprout from the base[5]. A climbing plant, it needs support and to be tied onto wires[4]. Any pruning is best carried out in spring[5].
Propagation
Seed - sow spring in a greenhouse. Only just cover the seed. 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. Division in spring[3]. Root cuttings in early spring[3].
