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

A soft, scale-leaved evergreen that is grown in gardens almost only as cultivars: slim columns or cones in blue-green, green or yellow that stay far smaller than the wild tree, which tops 50 metres (about 1.5 to 3 metres after ten years, eventually 2 to 10 metres depending on the cultivar). Good as a specimen, for screening or in a large tub, and it hardly needs pruning. Give it moist but well-drained soil and a sheltered, more humid spot, because it copes badly with dry air and drought and not at all with waterlogging.

Watch out for

Its most serious problem is Phytophthora root and collar rot: Lawson cypress is among the most susceptible garden plants. The foliage slowly fades to dull grey-green and then brown and the plant usually dies; there is no cure, so avoid heavy, wet or waterlogged soil and do not replant where one has already died this way. Phytophthora lateralis, the specialist pathogen that devastates the species in North America, has also turned up in Western Europe in recent years. In the hot, dry summers of Central Europe it suffers from heat and dry air unless watered and goes bare inside, and in cold winters the sunny, windward side can scorch. Weakened plants may also be attacked by the juniper jewel beetle, whose larvae tunnel under the bark and make whole branches die suddenly. Shops sell almost only its dwarf or columnar cultivars, which stay a fraction of the size of the species: check the size of the cultivar you choose before you buy.
