Chamaecyparis lawsoniana 'SNOW WHITE' Lawson cypress
Symbivit Tric (arbuscular)
Symbivit (arbuscular)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.
Snow White is a mistress of 7 dwarfs but where are they? Perhaps at Oregon State University that bred a whole range of those dwarf or compact Lawson cypress varieties in 1980’s called The Guardian® Series. Snow White is a picturesque Lawson cypress selection with mid green or almost blue green colour and small, creamy white new growths that make it look as if covered with stardust. The leaves are tiny and the branches are soft to touch.
It grows slowly into a teardrop or conical shape and needs no pruning to be dense. Still, you can shape in any way you wish, best in April or in midsummer.

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).
