What it's good for, and what it isn't

Japanese painted fern is a low, arching fern usually sold in its painted forms: the fronds are silvery grey with a green wash and burgundy midribs, and are at their most colourful in spring. Plant it in shade or part shade in humus-rich soil that stays moist without being waterlogged, where it really brightens dark corners. It is deciduous and late to come up in spring, so mark its spot; in direct sun and in soil that dries out the fronds scorch.

Watch out for

It has no serious pests or diseases. In Central Europe the hot, dry summer is its weak point: the fronds brown in sun and in soil that dries out, and the colour fades to green in the heat, so plant it in shade, mulch it and water it in drought.
