Hellebore 'Black Swan'

Helleborus × hybridus

  • 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!

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’).

Blechnum brasiliense 'Volcano'

Dwarf Brazilian Tree Fern, Hard Fern

  • New in 2015
Are Dicksonia tree ferns too large or expensive for you? We've found the answer - try the dwarf Brazilian tree fern instead! Blechnum brasiliensis 'Volcano' is an exciting new find for the home gardener, only recently introduced to the UK, but sure to be the next big thing! Compact plants lend themselves well to growing in patio pots; and throw up huge fronds up to 70cm (28") tall. The young fronds unfurl in a bronze volcanic hue turning a shiny green as they open. A relative of our native Deer Fern, this tender exotic fern thrives in low light, so it's perfect for giving a tropical touch to your home and garden. With tropical origins, Blechnum brasiliense requires a minimum temperature of 18C (64F) so it is best grown in a container in a heated conservatory and only moved outdoors during the warmest summer months. Height: 90cm (36"). Spread: 70cm (28").

Euphorbia amygdaloides 'Ruby Glow' (Large Plant)

Milkweed, Spurge

  • New in 2015

This handsome evergreen perennial produces vivid bright green flower bracts that seemingly glow above ruby-red foliage. As the foliage ages it becomes near black throughout the cold winter months before producing a new flush of vibrant red leaves in spring. Euphorbia amygdaloides 'Ruby Glow' has a neat compact habit producing rounded, well branched plants that look magnificent grown in large swathes. A colourful choice for moist borders. Although this Spurge will happily tolerate light shade, it is best grown in full sun for the strongest colour. Height and spread: 45cm (18").
