Chamaecyparis - False Cypress

Chamaecyparis

A genus of 8 species of trees that are related to the true Cypresses with a number of minute differences. Many are valued for their timber which is used for house interiors and fences.
They prefer deep, light, well drained soil but aren't very fussy. They are lime tolerant but will grow faster on soil with a PH below 7. They are also pollution tolerant.
Propagation is from seed sown in fall or spring. The cultivars can be reproduced from half hardened cuttings taken in summer. If grafted, that can be done in late winter to early spring. Though bagworm damage is rare...an infestation can cause severe damage, especially on some of the dwarfs that may be very expensive to replace. Inspect occasionally during the summer and treat accordingly if they occur.

Chamaecyparis formosensis ( Taiwan Cypress )
A very large tree native to Taiwan that is fast growing and reach reach 140 feet or more. Some records include: 10 years - 22 x 12 feet; largest on record - 220 x 80 feet with a trunk diameter of 27 feet. It can live up to 3000 years.
The pendant foliage in flattened sprays is medium green above with pale green or white markings below.
The cones are rust colored and round.
Hardy zones 7 to 10, tolerating as low as -11 F. It is very tolerant of hot, humid summers even thriving in eastern Texas eastwards through the Deep South. ENDANGERED

Rare in the eastern U.S., it can be found at Longwood Gardens among a few other parks and arboretums. It is planted frequently over much of Europe and has naturalized there locally. Unfortunately, this tree is threatened with extinction in the wild, as native stands have been getting wiped out by phytophora fungus since approx. 1952.
The foliage is bright to blue green in fan shaped sprays.
The early spring flowers are small and red.
The cones are grayish and ripening to rusty brown.
The ridged bark is red-brown.
Hardy zones 4 to 9; in the eastern U.S. it thrives on Long Island especially well but has a fairly wide range of adaptation. Tolerant of dry, alkaline soils and shade.

Chamaecyparis obtusa ( Hinoki Cypress )
The Hinoki Cypress is a large forest tree native of Japan. It is moderate growing to 2 feet per year ( rarely 3 feet ) and can grow to 27 x 10 feet in 20 years. One has already reached 80 feet at Princeton, NJ however much older trees to 1000 years old grow much larger to 180 x 40 x 10 feet in the wild.
The foliage is deep green above and striped silvery white below for the entire year.
The thick red brown bark peels off in strips and the trees are sometimes limbed up or planted in groves to show it off.
The Hinoki Cypress is hardy from zones 3 to 8 ( tolerating -40 F ) and it is recommended to never use grafted trees. Shading small nonestablished plants during winter can prevent freeze damage. It has proven generally hardy in the Ottawa area of Canada. Dwarf varieties of Hinoki Cypress(s) do surprisingly well in the harsh climate of Newfoundland on Canadas northeast coast.
They are not generally prone to pests and diseases, spider mites may occur on very dry sites. Cultivars can be grown from cuttings taken during autumn.

  1. does the Chamaecyparis pisifera (Golden Mop) act as a host for apple rust?
