Perennial & Biennial Plants


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.

Geranium 'Black Rose'

Pelargonium, Rosebud Geranium

The full, rounded buds of Rosebud Geranium 'Black Rose' resemble dainty roses when they first break open, then cluster together to form a pretty posy. This vigorous, trailing variety has the exceptional garden performance of other ivy-leaf geraniums, but their unique flower form truly sets them apart. With regular deadheading, they will spill from windowboxes, containers, and hanging baskets, blooming profusely throughout the summer. Trails to: 45cm (18").
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.

Dianthus 'Blackjack'

Carnation

  • New in 2015

New modern cut-flower quality carnation plants packing the heavenly scent of antique varieties! Modern breeding work has seen the unmistakable scent of carnations all but disappear in the search for longer, cut flower-quality stems. Fortunately Carnation 'Blackjack' bucks that trend. Not only does it offer a unique colour combination, the near black blooms also bring punchy clove-like fragrance to the garden. A perfect border carnation, it also performs well in containers. Originally planned for the commercial cut flower market, you won't be disappointed by the endless supply of fresh stems either! Keep the colour and scent in the garden or use Dianthus 'Blackjack' as your very own cut flower carnation. Height and spread: 50cm (20").
