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.

The leaves and the flowers are cardiotonic, diaphoretic, diuretic, emetic, expectorant and sternutatory[7, 147, 218]. A decoction of the leaves has been applied externally in the treatment of scabies[7], and to reduce swellings[240]. This is a very poisonous plant, containing a powerful cardiac toxin[240], and should only be used with extreme caution[7, 147]. The root is powerfully resolvent. Because of its poisonous nature it is only used externally. It is beaten into a paste with water and applied to chancres and ulcers on the penis[240]. An oil prepared from the root bark is used in the treatment of leprosy and skin diseases of a scaly nature[240]. The whole plant is said to have anticancer properties[218].

Other Uses

The plant is used as a rat poison[46], a parasiticide[7] and an insecticide[100]. The pounded leaves and bark are used as an insecticide[272]. A green dye is obtained from the flowers[168]. The plant is commonly used for informal hedging in the Mediterranean[89, 200], though it is too tender for this use in Britain[K]. The leaves contain small amounts of latex that can be used to make rubber[227], though the amount is too small for commercial utilization[K]. The plants have an extensive root system and are often used to stabilize soil in warmer areas[148].

Grows well in maritime gardens, tolerating salt-laden winds[200]. This species is not very hardy in Britain, though plants tolerate temperatures down to -5°c and short periods of temperatures down to -10°c[184, 200, 260]. A popular greenhouse pot plant that can be grown outdoors in the summer, it can be grown outdoors all year round in the milder areas such as Cornwall[1, 260]. A very ornamental plant[1], there are many named varieties[200, 260]. Plants are shy to flower when grown outdoors[49, 59]. The flowers have a soft sweet perfume[245]. Special Features: Not North American native, All or parts of this plant are poisonous, Fragrant flowers, Blooms are very showy. 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].

Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for at least their first winter before planting them out in early summer. Cuttings of half-ripe side shoots, August/September in a frame. Good percentage[78]. Cuttings of mature leading shoots[1].
