Hellebore 'Black Swan'

Helleborus × hybridus

  • New in 2015
  • T&M Exclusive
  • Grow the most prestigious Christmas Rose in your garden
Winter-flowering hellebores are true garden gems, producing luxuriant blooms when little else is in growth, let alone flower! Fresh from our unique hellebore breeding programme we have hit on the perfect form and habit with Hellebore ‘Black Swan’. The sumptuously dark velvety petals, starkly contrasted by pure white stamens, are a vast improvement on older black-flowered hellebore plants. 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’).
