Evergreen to semi-evergreen groundcover with heart-shaped, glossy green leaves grows 4" tall and slowly spreads to 15" wide. It spreads nicely in the moist, humus-rich layer that accumulates beneath trees in woodland settings. In Europe, they're ubiquitous on the floor of the Beech forests. Small, leathery, chartreuse flowers go unnoticed beneath dense foliage but deserve a peek.
