Also known as herbaceous plants, perennial plants live for 2 or more years and flower every year. Biennial plants live for up to 2 years, flowering profusely in their second year before setting seed and dying.

  • The very best hellebores that money can buy

Exquisite cup shaped, red-black blooms appear like jewels in dull winter borders.

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! 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').

Pennisetum 'Blackjack'

Fountain Grass

  • Add texture and movement to your garden
  • A real designer's plant

Ornamental grasses add an architectural element to planting schemes, while their airy foliage adds movement as it catches the breeze. Pennisetum 'Blackjack' went down a storm in our summer trial garden! The shimmering, deep purple stems go on to produce black feathery plumes throughout the summer. The fluffy seedheads can be cut to make elegant dried flowers or left on the plants to give garden birds a seasonal treat. Add these pennisetum plants to beds, borders and containers to get the designer's look in your garden this season. Height: 1.2m (4'). Spread: 45cm (18")
