Uses

Toxic parts

Plants contain a narcotic toxin called Ledel. This toxin only causes problems if the leaves are cooked for a long period in a closed container[1].

Edible uses

Notes

A tea is made from the leaves[1][2]. Some caution is advised, see the notes above on toxicity. It would be better to brew the tea in cold water by leaving it in a sunny place, or to make sure that it is brewed for a short time only in an open container. The leaves are used as a flavouring, they are a bayleaf substitute[1].

Unknown part

Condiment
Tea

Material uses

The leaves are used to repel moths, mice, rats etc[1].

Unknown part

Repellent

Medicinal uses(Warning!)

The leaves and young flowering shoots re astringent, diaphoretic, diuretic, laxative and stomachic[1].

Propagation

Seed - surface sow in a shady part of the greenhouse in February or March[3][4]. Another report says that the seed is best sown in the autumn as soon as it is ripe[5]. Germination is variable and can be quite slow. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow the pots on in a shady frame for 18 months before planting them out into their permanent positions[3].

Cuttings of half-ripe wood, 5 - 8cm with a heel, July/August in a frame. Plant out in spring. Fair percentage[3]. Cuttings of mature wood, November/December in a frame[4]. Layering in the autumn. Takes 12 months[3].

Cultivation

Requires a lime-free loam or peaty soil[6][7]. Prefers a moist humus-rich acid soil in shade or semi-shade[8]. Plants grow better if they have certain fungal associations in the soil. The best way of providing this is to incorporate some soil from around well-growing established plants into the soil for the new plant[8].

Plants are hardy to about -15°c[8]. The leaves are covered in tiny spots or glands from which a strong, resinous scent is given off[9]. The flowers also have an aromatic perfume[9]. Very closely related to L. glandulosum[6], and considered to be no more than a sub-species of it by some botanists[8].

Plants benefit from removing the dead flowers before they set seed[5]. This prevents them putting too much energy into seed production at the expense of more flowers and leaves.
