This tough, low-maintenance perennial thrives in a range of garden conditions,  including dry shade and poor soils, once established. 
 When planting, choose a site with well-drained soil in partial shade to full  sun, and incorporate organic matter to improve soil structure. 
 Water regularly until established, but once settled, this geranium becomes more drought-tolerant and requires lower maintenance. 
 Avoid hoeing around the plant, as its surface-growing rhizomes can be easily  damaged—weed by hand instead. Deadhead spent flowers to prolong blooming and   lightly trim back foliage after flowering to keep plants looking tidy.  
 In autumn or early spring, divide congested clumps to rejuvenate growth and   spread the plant to other areas of the garden. A light mulch of compost or  leaf mould in spring will support healthy foliage and flowering.
