About this genus:

Potentilla (po-ten-til-la) is a genus containing over 300 species flowering plants in the rose family (Rosaceae) generally only found throughout the northern continents of the world (holarctic).. They are commonly called cinquefoil.

Typical Potentilla look most similar to strawberries, but differ in usually having dry, inedible fruit (hence the name barren strawberry for some species). The flowers are usually yellow, but may be white, pinkish or red. The accessory fruits are usually dry but may be fleshy and strawberry-like, while the actual seeds each one technically a single fruit are tiny nuts.

First was described by Linnaeus in 1753 they get their name from the latin, potens, meaning potent – the genus has been said to be useful in medicine and magic at least since the time of Hippocrates.

Potentilla is quite versatile and will tolerate most non-waterlogged soils in part sun or shade. They almost always look straggly in pots – so we rarely sell as many as we should. However when out of their pots they are no longer straggly and must be one of the best (most potent?) plants in the garden. Often to be found nestled into the rockery or atop a garden wall alongside Campanulas or Stachys, we also have ours in borders with Astilbe and Eryngium.

A spectacular and highly unique perennial, Potentilla ‘Arc en Ciel’ (meaning ‘Rainbow’) brings a dramatic touch of luxury to the summer garden. From early summer through to autumn, it produces a profusion of semi-double, cup-shaped flowers. The petals are a rich, velvety crimson-red, elegantly edged and streaked with a brilliant margin of golden-yellow.

The attractive, strawberry-like palmate foliage forms a low, spreading mound of fresh green that serves as a perfect foil for the bi-coloured blooms. Fully hardy and easy to grow, it’s perfect for rockeries, cottage gardens, or front-of-border positioning.

Summer flowering. Best in a sunny position in most well-drained garden soils. Height & spread: 40cm x 60cm (16″ x 24″).
