Hardy Geraniums (or Cranesbill) are said to be the most popular perennials in Britain, adding traditional colour as well as low, leafy ground cover from early summer through to late autumn. Not to be confused with the bedding Geranium, it is hardy so will come back every year. This is a pretty blue variety called 'Johnson's Blue'. Sold as an established plant in a 12 cm pot ready to be transferred to your garden. You can buy one, two or three plants with this order.
