Watch out for

Common sage

It is short-lived: within a few years it turns woody and bare at the base and needs renewing. It will not stand waterlogging and the roots rot in wet soil. In Central Europe hard winters without snow cover can scorch it or cut it back, and variegated and purple-leaved cultivars are more frost-tender. Powdery mildew appears in damp, still air, and leafhoppers and spider mites can mottle the leaves in hot summers.

Cottage pink

The most common failure is crown rot: in heavy, wet soil that stays damp in winter the cushion browns in patches and dies, so plant it in a gritty, open mix and do not cover it with moisture-holding mulch. It is short-lived, going bare after 3 to 5 years, and has to be renewed from cuttings. It dislikes very hot, humid summers, when flowering stops early. Slugs, aphids, thrips and spider mites can damage it.
