Helleborus Walberton's Rosemary, 2/3LHelleborus Walberton's Rosemary is an enchanting, hardy perennial that provides a much needed touch of colour in the winter garden. Leathery, five lobed leaves form luscious clumps of semi evergreen foliage, ideal in a sheltered border or container. The petals (in reality sepals) turn from an unusual pink washed green to a soft pink as it matures.
