In this range you'll find an impressive selection of perennial plants and biennial plants, which are perfect for beginners and experienced gardeners alike. 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. Both are great for beds and spring displays and there are many delightful plants to choose from. Use the selections in the left menu to select the right plants for your garden.

Ajuga reptans 'Black Scallop' (Large Plant)

Ajuga reptans 'Binblasca', Bugle

Ajuga reptans 'Black Scallop' is a highly attractive variety of Bugle. The violet blue flower-spikes appear from late spring against a dense matt of glossy, liquorice-black foliage. This dark leaved perennial is more sun tolerant than many cultivars, with the foliage becoming blacker when grown in full sun. A superb groundcover plant, Bugle is a tough and reliable evergreen that copes in almost any soil conditions. Ajuga reptans 'Black Scallop' is particularly effective at the front of borders, creeping through rockeries or as groundcover in wildlife gardens where it will attract pollinating insects. Height: 15cm (6"). Spread: 60cm (24"). More info

Geranium 'Black Velvet Mix' F1

Pelargonium, Zonal Geranium, Zonal Pelargonium

 Customer Rating
  • Rarely available

Dark, enigmatic foliage makes a startling foil for the beguiling bright blooms of Geranium 'Black Velvet Mix' in four striking colours. The unique black leaves, produced on upright bushy plants, are edged with just a hint of green. This boldly coloured zonal geranium makes a striking addition to pots, beds and borders for long lasting summer colour. Height: 40cm (14"). Spread: 30cm (12").


Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.
