Plant details

This beautiful hellebore was introduced by Robin White. It is a shorter plant than ordinary H.. x sternii and has been carefully selected for its purple stems, silvery-grey, marbled foliage, and pink-tinged green flowers. Its fine qualities have been recognised by the Royal Horticultural Society who have given it their prestigious Award of Garden Merit (AGM). Like its parent, it is easy to grow and enjoys a sunny position in well-drained soil.
