Of all garden Potentillas, this must surely be one of the most attractive. Heart-shaped, rich raspberry red petals forming saucer-shaped flowers; a wonderful colour in its own right - but add a deep velvet red centre, appearing just like an ink blot which has diffused outwards and the flowers radiate beauty; a real garden treasure. Flowering over a long period, an absolute must for the perennial border and cottage garden alike. Flowers summer. Height: 60-90cm (24-36in)
