This beautiful new semi-dwarf cultivar is quite a winner with compact heads displaying crimson-eyed, bright pink flowers, and petals attractively crinkled just like crepe paper. New buds open repeatedly in a long succession, from spring until late summer.

Sowing advice:
For best results, sow seeds immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. However, we sow most seeds in an unheated greenhouse and wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.

Cultivation:
Although drought-hardy when established, to bloom its best it should have moderate watering during the summer months. Seasonal fertilizing with an evergreen fertilizer isn’t essential, but can benefit especially a clump that is in a crowded perennial garden.
The main flowering period is June, July and August and it usually continues to first frosts. If at any point it stops flowering, cut the stems back to get a second flush of leaves and buds. It might die back naturally at the end of the season otherwise cut back stems that remain to ground level in spring.
Potentilla is a long-lived plant that can be divided every three years or so, in spring.

Plant Uses:
Cottage/Informal Garden, Flower Borders and Beds, Rock gardens, Containers. Coastal.

Origin:
Potentilla is a genus containing over 300 species of annual, biennial, and perennial herbaceous flowering plants in the rose family, Rosaceae. Potentilla are generally only found throughout the northern continents of the world (Holarctic), though some may even be found in montane biomes of the New Guinea Highlands.
Potentilla nepalensis is a species that is native to East Asia and West Himalayas, from Pakistan to Nepal. The species can be found in grazing grounds and cultivated areas, at elevations of 2,100 to 2,700 metres (6,900 to 8,900 ft) above sea level.
