Boehmeria japonica

(L.f.) Miq.

Urticaceae


Boehmeria japonica is a very variable species and has, in the past, often been treated as a number of distinct species. However the differences between these species is not clearcut, with many intermediary forms being found. The complex of species is treated here as a single taxon subdivided into three partly intergrading varieties, differing in a combination of indumentum and leaf morphology with incompletely overlapping distributions, the morphological distinctions slightly obscured by intermediates between them and by a group of hybrids, some of uncertain parentage[

Propagation

Seed - sow spring in a warm greenhouse, only just covering the seed. 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.
Division in spring. Very easy, larger divisions can be planted straight into their permanent positions whilst smaller clumps are best potted up and kept in a cold frame until they are growing away well.
