Geranium versicolor (Pencilled Cranesbill) Amazingly floriferous, each petal looking as if it has been drawn on with a coloured pencil. Semi-evergreen mounds of foliage make great groundcover, slug & rabbit resistant, attractive to bees & not fussy on soil conditions in sun or part shade. Height & spread 45-60cm (18-24"). Hardy perennial. Geranium pratense Summer Skies Everybody loves Geraniums as they are drought tolerant, great weed suppressors, tolerant of all soil conditions, flower for six months of the year, are slug proof & extremely hardy too but only Summer Skies has the sparkling yellow centre. Prefers sun or part shade. Height & spread 60-90cm (24-36"). Hardy perennial.
