Potentilla nepalensis ‘Roxana’
Flowers from June-September, red centre fading to yellow and pink outer petals. Grows to about 1 foot 4ins with a similar spread. Prefers a moist to well drained soil in full sun or part shade. As the name would suggest the species comes ffrom the Himalayas and is very hardy. We grow it in a large pot on our patio.
