Geranium pratense ‘Double Jewel’ has a unique white colour that sets it apart from other hardy Geraniums. Its white petals form elegant rosettes that have a mauve-pink centre, creating a beautiful contrast. It produces blooms from early summer on top of a loose mound of finely cut foliage. This lovely perennial is perfect for filling gaps at the front of herbaceous borders, and fits well into cottage garden planting schemes. Height: 40cm (16"). Spread: 30cm (12").
