Ledum glandulosum (common name: labrador tea)

Propagation: Seed - surface sow in a shady part of the greenhouse in February or March[1][2]. Another report says that the seed is best sown in the autumn as soon as it is ripe[3]. 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[1].

Cuttings of half-ripe wood, 5 - 8cm with a heel, July/August in a frame. Plant out in spring. Fair percentage[1].

Cuttings of mature wood, November/December in a frame[2].

Layering in the autumn. Takes 12 months[1].

Division.

Cultivation: Requires a lime-free loam or peaty soil[4][5]. Prefers a moist humus-rich acid soil in shade or semi-shade[6]. Plants flower more freely when grown in a sunny position. 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[6].

Hardy to at least -15°c[6].

The leaves are covered in tiny spots or glands from which a strong, resinous scent is given off[7]. The flowers also have an aromatic perfume[7].

Plants benefit from removing the dead flowers before they set seed[3]. This prevents them putting too much energy into seed production at the expense of more flowers and leaves.

Range: Western N. America.

Habitat: Wet montane meadows and open woods[8].

Edibility: An aromatic tea is made from the fresh or dried leaves[9][10][11]. The dried leaves are often mixed with non-aromatic leaves such as comfrey[10]. 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[9].

The fresh leaves can be chewed[10].

Medicinal: The leaves and young flowering shoots re astringent, diaphoretic, diuretic, laxative and stomachic[9].

Usage: The leaves are used to repel moths, mice, rats etc[9].

Soil: Can grow in light, medium, and heavy soils.

In Leaf: Evergreen

Flower Type: Hermaphrodite

Known Hazards: 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[9].
