Perennial geraniums are a must have in every perennial border, low growing but with plenty of flower. Geraniums have a long flowering period and are very hardy.
The RHS plant of the centenary at the Chelsea flower show in 2013. What more can be said?! A beautiful mid blue flower on a large clump forming perennial, idea for the front of borders spilling over onto the lawn. Produces a mass of flower all summer. A top seller.
Use a granular fertiliser at planting and add plenty of organic matter to the soil at planting. Liquid feed to get established and through the season to get the best results. The plant will die back in winter, so can be tidied up in autumn/ winter.
