It is hardy to zone 7. It is in flower in May. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid soils and can grow in very acid soil. It can grow in semi-shade (light woodland). It requires moist soil.


Cultivation :

Succeeds in a most humus-rich lime-free soils except those of a dry arid nature or those that are heavy or clayey. Prefers a peaty or well-drained sandy loam[1]. Succeeds in sun or shade, though it prefers a shady position. A pH between 4.5 and 5.5 is ideal[1]. Succeeds in a woodland though, because of its surface-rooting habit, it does not compete well with surface-rooting trees. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers. Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact. A very ornamental plant, it is the parent of many cultivars. Plants in this genus are notably susceptible to honey fungus.

Propagation:

Seed – best sown in a greenhouse as soon as it is ripe in the autumn and given artificial light. Alternatively sow the seed in a lightly shaded part of the warm greenhouse in late winter or in a cold greenhouse in April. Surface-sow the seed and do not allow the compost to become dry. Pot up the seedlings when they are large enough to handle and grow on in a greenhouse for at least the first winter. Layering in late July. Takes 15 – 24 months. Cuttings of half-ripe wood, August in a frame. Difficult

Medicinal Actions & Uses
Anaesthetic; Analgesic; Sedative.

The flowers are analgesic, anaesthetic and sedative. They are applied externally in the treatment of arthritis, caries, itch, maggots and traumatic injuries.  The root is used in the treatment of arthritis, rheumatism and traumatic injuries.

Other Uses

Insecticide.

The powdered flowers have a mild insecticidal effect.

Cultivars
There are some named forms for this species, but these have been developed for their ornamental value and not for their other uses. Unless you particularly require the special characteristics of any of these cultivars, we would generally recommend that you grow the natural species for its useful properties. We have, therefore, not listed the cultivars in this database

Known Hazards: The plant is very toxic. The pollen of many if not all species of rhododendrons is also probably toxic, being said to cause intoxication when eaten in large quantities.

It is hardy to zone 0. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant)
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Cultivation:-
We have very little information on this species and do not know if it will be hardy in Britain. However, judging by its native range, it could succeed outdoors at least in the milder areas of the country. It is likely to require a sheltered sunny position with some protection from winter cold.

Propagation:-
Seed – we have no information for this species but recommend sowing the seed in a warm greenhouse, preferably as soon as ripe if this is possible. 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 year. Plant out in early summer after the last expected frosts and consider giving the plant some protection from the frost during at least its first winter outdoors.

Medicinal Actions & Uses:-

Depurative; Febrifuge.

Febrifuge, depurative. Dispels clots. All parts of the plant are used as medicine for the treatment of dysentery, diarrhea, rupture, cough, etc.

Other Uses

Oil.

The seeds contain up to 20 per cent of oil, which is used in making soap and as a lubricating oil.
