Propagation

Seed - best sown as soon as possible in a greenhouse. Germination can be erratic but usually takes place within 20 - 60 days at 20°c[164]. When 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 in late spring or early summer after the last expected frosts. Root cuttings, 6 - 8cm long, December in a greenhouse. High percentage[78]. Division of suckers in the dormant season. Very easy, they can be planted out direct into their permanent positions if required.

The seeds make a good blue dye. Remove the outer covering of the seeds and simmer what is left in water. Use this water to dye wool or silk mordanted with copper. The leaves can also be used as a dye.

It is not uncommon to see the genus written Clerodrendron, but I suspect this is an old form. Clerodendrum is one of several genera in Verbenaceae which may be reclassified as Lamiaceae.
