Care
This is a fairly vigorous and invasive plant so we suggest growing in a container. Humus rich moist soil sun to part shade. Ants dislike it.
Reaching only around 15 cm in height this is a plant that grows well in full sun in a humus rich fertile and well drained soil. It will spread by underground runners, so consider growing it in a contained area or perhaps in a pot.
It is easily removed if it spread to far.
Seek professional advice before using this plant.
