(RHS Color Chart Red Group 53C to 48C). Fading occurs as in related Potentillas, but to a pale pink color, but this is believed to be reduced by partial shade and increased by very wet or very hot, dry conditions. The plant is more dwarf than its parent. Present size of parent plant is 40 cm. high, 85 cm. maximum diameter (at age of 31/2 years).
