Watch out for

Evergreen candytuft

It has no serious pests or diseases. Most losses come from crown rot in wet, poorly drained soil, so on heavy ground plant it in a raised or gritty spot. In snowless, windy, sunny winters the evergreen foliage can scorch and thin out; a light cover of conifer branches helps. It can wilt in summer heat and long dry spells and is grateful for watering then. Slugs, snails and caterpillars may chew it.

Heather

In most gardens in Central Europe the limy, heavy soil and hard tap water make it yellow and die quickly unless it is planted in an acidic medium. It copes badly with hot, dry summers: once dried out it does not resprout, while in permanently wet, airless soil stem and root rot kill it. In windy, sunny winter weather without snow cover the foliage can brown. Spider mites and scale insects occur. Potted plants bought for autumn decoration usually last a single season unless they are moved into suitable soil.
