Other Uses

Insecticide  Rootstock  Wood

This plant is often used as a rootstock for other members of the pea and bean family[11]. The seeds contain the poisonous alkaloid 'cytisine'. This has insecticidal properties similar to nicotine (Nicotiana spp.) but cannot be recommended for used since it needs to be used in such a concentration that it can then be absorbed over a wide area of the body with possibly fatal results[4]. Wood - coarse grained, durable, dark coloured and very hard, it can be used as an ebony substitute[4, 11, 46]. It is much in demand among turners, and is used in making instruments and furniture especially where strength and smoothness are important[4, 11, 46, 61].

Cultivation details

A very tolerant and easily grown plant, it succeeds in almost any soil or situation[1] so long as it is not water-logged[11]. It grows well in heavy clay soils. Succeeds in cold exposed situations and tolerates industrial pollution[200]. Plants can be successfully transplanted even when quite large[200]. The flowers are delicately scented[245]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. This species is notably susceptible to honey fungus[200]. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is branching: a heart root, dividing from the crown into several primary roots going down and out [2-1].

Plant Propagation

Seed - best sown as soon as it is ripe in a greenhouse or cold frame[200]. Germination is usually very quick and good[78]. Prick out indoor-sown seedlings into individual pots when they are large enough to handle and plant them out in the summer. Another option is to pre-soak the stored seed for 12 hours in warm water and sow in an outdoor seed bed in early spring. These plants an be allowed to grow on in the seedbed for two years before planting them out in the winter. Cuttings of mature wood in late winter planted in the open ground[200].
