Chamaecyparis lawsoniana 'WISSELII' Lawson cypress, false cypress
Chamaecyparis
The genus Chamaecyparis comprises a small group of coniferous trees native exclusively to eastern Asia and the western regions of North America. Botanically, it belongs to the cypress family and is characterised by its fine branch structure, scale‑like foliage and remarkable diversity of forms and colours, which has made it one of the most important genera of ornamental conifers. The genus was first formally described by Stephan Ladislaus Endlicher (1804–1849) in the first half of the nineteenth century, at a time when Europe was becoming increasingly familiar with the flora of the Far East. Fossil evidence suggests that the ancestors of modern false cypresses were once far more widely distributed, making the genus another example of woody plants that survived major climatic shifts in restricted refuges.
Lawson cypress is native to northwestern America, from Oregon to northern California. It was first discovered by European Americans near Port Orford, Oregon, and was introduced to horticultural market in 1854. It was described by the Scottish botanist Andrew Murray (1812-1878) and named after another Scottish botanist and merchant, Charles Lawson (1795-1873), who became famous by importing new plant species from America to Britain. This cypress tree was one of his discoveries. It is a hardy, evergreen conifer with soft, scale-like needles. Perhaps all over the world in temperate climates, it is widely planted in gardens and parks and is popular for its variability. There are many colourful varieties that brighten up compositions of dark green shrubs and trees and perform also in decorative outdoor containers.
Wisselii is a gorgeous variety of Lawson cypress. It was found by a Dutch grower F. van der Wissel in 1888. It is an evergreen conifer of strictly upright, columnar growth and picturesque habit. Its branches are covered with scale-like, emerald green needles.
Wisselii cypress grows rather slowly, and can be only 1 meter tall at the age of 5 years. In maturity, which is anything over 50 years, it can reach as tall as 6 meters, and not more than 2 meters wide. Prune or shape it in mid spring or midsummer. Do not cut into old wood.

Lawson cypress prefers moist but well-drained, slightly acidic soil but is adaptable to almost all types of soil. Grow it in full sun or half shade either in a garden bed or in a container where moisture must be regularly checked but remove the saucer (it requires more frequent watering than e.g. pine tree) and the plant has to be fed once it has consumed all nutrients from the original soil. In a border it requires no maintenance at all. Fully hardy to min. -29 °C (USDA zone 5).
