Some more propagation by division. Pretty basic- I stuck a fork into a patch of Trachystemon orientalis and levered out a section of rhizome to replant elsewhere.

 Sometimes called Oriental Borage or Early Flowering Borage, it's tough as old boots. The flowers resemble those of the annual Borage though it's a different species albeit of the Boraginaceae. Large coarse leaves last through summer. 

 Use as ground cover in dry shade. Invasive or vigorous depending how you look at it; few other plants will flourish in deep, dry shade so it has its uses.
