More About Acaena inermis 'Purpurea'

  • May be clipped or mown back in early spring.
  • Easily increased by ripping the patch apart into small pieces in spring or early fall.

Although nice in the rock garden, plants can grow beyond where they are wanted, so keep a firm upper hand. Evergreen in mild winter regions.Amazing amethyst colored foliage creates a dramatic carpet of color. In summer creamy-white flower spikes will delight you against the foliage. If planted in full sun the foliage will turn ruby red. Perfect for spilling over retaining walls or surrounding taller perennials. It will only tolerate light foot traffic.
