Plant of the Day (March 19th, 2012) - Chamaecyparis pisifera agg. (Subclades "Squarrosa" & "Filifera")

Conifers, confiers and no end. After Thuja occidentalis, Xanthocyparis nootkatensis and Chamaecyparis obtusa comes the next evergreen tree from the Cupressaceae family. This plant is Chamaecyparis pisifera (Siebold & Zucc.) End. from the Cupressaceae family. In Germany, we call this species “Erbsenfrüchtige Scheinzypresse” or “Sawara Scheinzypresse” while common English terms are “Sawara Cypress” or simple “Sawara”.

C. pisifera  "Aurea" (Subclade: flifera) -
this cultivar has a shrub-like habitus

Again it's a tree, which can reach an average height of 50 metres (164 feet). Wild forms have a pyramidal habitus. Mature leaves are very pointed, scale-like (yeah it's boring, but this is typical for many Cupressaceae) and until 3 millimetres long. They are overlapping each other and are arranged in four rows per branch. The dorsal site is dark-green, while ventral side has a white shimmer.

C. pisifera "Boulevard" (Subclade: squarrosa) - habitus

The bark is reddish. It's also very fibrous and fells off in long, thin strips.

As with the most Cupressaceae, C. pisifera is monoicous with male and female cones. The male cones are brown and inconspicuous. Young female cones are looking like a green pea, which is also the reason for the latin name of the species (“pisisfera” means “pea-like”). With age, they get a dark-brown colour. Each cone consists of ten seed-scales The seeds are winged.

They are also many cultivars of C. pisifera ,which are looking completely different from the wild form. My photos e. g. show trees from the clades “squarrosa” and “Filifera”. The “filifera” cultivar is “Aurea”; named after the hanging, whip-like branches with their golden-yellow colour. The “squarrosa” cultivar is “Boulevard” with its blue-green leaves and the silver shimmering ventral side.

The wild-form is native to Japan, where “Sawara” (the Japanese name) is one of the “Five holy trees of Kinose” (like Chamaecyparis obtusa). It prefers fresh soils in temperate regions. However, C. pisifera is also a very popular ornamental tree (especially the wild forms) and can be found out of Japan in Parks, Gardens and on cemeteries.
