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

A creeping perennial with coin-shaped leaves that roots wherever its stems touch the ground and carries small bright yellow cup flowers in summer; a golden-leaved form is widely planted too. It quickly knits into a mat in damp spots, by a pond, under trees or between stepping stones, and trails nicely from pots and walls. Plant it in moist or wet soil and only where it has room to roam, because it creeps into the lawn and between neighbouring plants.

Watch out for

The main problem is its spread: the rooting stems quickly outgrow their allotted space, so it needs pulling back every year and should not be planted among delicate low perennials. In the dry, hot summers of Central Europe it scorches and thins out in sunny spots without watering, the yellow-leaved forms most of all. Rust and leaf spots can occur but are rarely serious.
