Helianthemum 'Wisley Primrose'
rock rose
Forming a spreading mound of grey-green leaves, this mainly-evergreen shrub looks wonderful planted in an alpine bed, en masse on a slope, or in a pot on the terrace.
The lemon coloured flowers appear over a long period from late spring. Once established it becomes drought tolerant and it thrives in hot, sunny spots where little else will grow. It also copes well with salt laden wind so is a good choice for coastal gardens.
