Material uses

This section contains historical Plants For A Future notes marked noncommercial.

A commercial insect wax is produced on the branches as a result of eggs being laid by insects[1]. Another report says that the wax is produced by the plant due to the stimulation of the feeding insects[12][3]. Yet another report says that the wax is produced by the insects[5]. It is used for candles and as a polish for earthenware pots, book edges etc[5]. The plant can be used as a hedge[1]. It is very amenable to trimming.

Propagation

This section contains historical Plants For A Future notes marked noncommercial.

The seed does not require any pre-treatment and can be sown in the spring in a cold frame[2]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 5 - 10cm with a heel, July/August in a frame. Very easy[14]. Cuttings of mature wood, 20 - 30cm in a sheltered outdoor bed in November/December. High percentage[14].

Cultivation

This section contains historical Plants For A Future notes marked noncommercial.

A very tolerant and easily grown plant, it succeeds in any soil that is not impoverished or water-logged[1][7]. Grows well in heavy clay soils. Succeeds in sun or semi-shade[8]. Closely related to L. lucidum[1][9]. There are many named varieties selected for their ornamental value[9]. This species is notably resistant to honey fungus[9].
