Winter-flowering hellebores are true garden gems, producing luxuriant blooms when little else is in growth, let alone flower!

Where older types tend to face their blooms to the soil below, 'Black Swan' holds its jet-black blooms up for all to see. This classy performer deserves a place in every garden as the star attraction through winter. Height and spread: 60cm (2').
