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 'Double Flowered Collection'

Hardy Geranium, Cranesbill

Enjoy our selection of the very best double-flowered cranesbills. Every bloom is a pretty posy of vibrant colour and unlike their single flowered relations, these hardy geraniums won't self seed, so the flowers last even longer. These cottage garden favourites will quickly blend with other herbaceous perennials to create colourful groundcover, and look equally attractive in borders or containers. Height: Up to 90cm (36"). Spread: 60cm (24").
  • Collection comprises 1 plant each of:
  • Geranium himalayense 'Birch Double' (left) - Vigorous and versatile, this superb cranesbill tolerates almost any situation; even full shade.
  • Geranium pratense 'Laura' (bottom right) - Long lasting, weather resistant, double white flowers are produced from June onwards on upright, downy stems.
  • Geranium pratense 'Summer Skies' (top right) - The double blooms of Geranium pratense 'Summer Skies' may look delicate but this hardy herbaceous perennial is tough and undemanding.

Geranium 'Red Sybil'

Pelargonium, Rosebud Geranium

The full, rounded buds of Rosebud Geranium 'Red Sybil' 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”). Geranium 'Red Sybil' is protected by Plant Breeder's Rights - propagation prohibited.
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.
