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.
