Acaena Inermis Purpurea
Best grown in evenly moist, sandy, well-draining soils in full sun. Tolerates some shade in climates with hot summers. Tolerant of poor, shallow, and rocky soils as long as they are well-draining. Hardy in Zones 6-10. Semi-evergreen in the warmer end of its hardiness range, but will die back to the ground in climates with persistent cold. Easily propagated by division. Will spread rather quickly in ideal climates and can become aggressive. This and other species of Acaena are considered invasive in some areas outside their native range.
