Planting

Use dappled to full shade with humus-rich, moist but draining soil. It suits woodland edges, shaded borders and mixed containers where the root zone stays cool.

Care

Water during dry weather; this is not a drought-tolerant ground cover. Remove winter-damaged leaves as growth restarts, and allow young runner plantlets two growing seasons before separating them.
