Geranium sanguineum (Bloody cranesbill)
Geranium sanguineum (bloody cranesbill) is a hardy, spreading perennial that produces vivid magenta-pink flowers with darker veining, creating a jewel-like carpet at the front of borders and in rock gardens.
Staying compact at around 20cm tall, it spreads to form a neat, bushy groundcover that flowers over a long period in summer and often develops attractive autumn colour as the season cools.
Plant in full sun or partial shade in moderately fertile, well-drained soil. It copes with many soil types and is particularly useful where you need low, reliable cover without lots of maintenance.
Water to establish, then only during prolonged drought. A light trim after the first flush can encourage fresh foliage and repeat flowering, and dividing clumps in spring can rejuvenate older plants.
Ideal for edging, underplanting and wildlife gardens, this cranesbill pairs beautifully with roses and grasses, and it provides a long-lasting, pollinator-friendly summer display.
