A Selection of Cupressus

These true Cypressus have a number of species that have produced very attractive garden forms. The Cupressus arizonica selections are the hardiest of this genus with macrocarpa producing the greatest variation of the genus.

Rooting is used to propagate some selections but I believe grafting onto Cupressus x leylandi to be the best method of propagation. The root system is strong and there are no compatibility problems. Selections grafted onto Juniperus and Thuja often exhibit an overgrowth syndrome where the cultivar outgrows the understock and the weakened root system causes the plant to eventually blow over.

Cupressus arizonica 'Blue Streak'

A dense, conical tree; grows about 20 cm per year; has blue foliage and demonstrates a climatically influenced mature shape that is characteristic in Australia, warmer areas it is narrowly columnar, being about 1 m wide when 3 m tall and almost cylindrical in outline, but in the cooler areas around Melbourne, Australia it is typically pyramidal; found as a seedling by Vic Levey of Queensland, Australia, and introduced in the late 1970's





Cupressus arizonica 'Chaparral'

A dense, broadly columnar selection; foliage is fine, almost juvenile, and creamy-white, does not burn in the full sun; discovered as a seedling by John Emery, Drue Nursery, Berry, New South Wales, Australia, and introduced about 1980; strikes from cuttings better than the species. z7




webcupglconcaaurea.jpg (91445 bytes)

 Cupressus arizonica 'Conica Aurea' as observed growing in an English garden. It grows large but is very dense and has a sulphur yellow color.









Cupressus arizonica 'Spire'

A synonym for 'Angaston', it forms an upright blue tree with all of the branches hanging down along the trunk; after ten years the height can be 6 m with a width from .5 m to 2 m; found as a seedling in the Barossa Valley, South Australia in 1980. z7

  This plant is identical to 'Raywood's Weeping' in my garden. I believe these to be synonymous.





   Cupressus arizonica 'Sulphurea' grows much slower than the other arizonica selections, about 6" (12-15 cm) per year and becomes a dense, narrow pyramid of sulfur yellow foliage that will not burn in the full sun. It was first offered by Renault Freres Nursery, Gorron, France.

A selection that grows as wide as high with an irregular outline; in ten years it will be about 6 m high by 5 m wide; discovered by John Emery, Drue Nursery, Berry, New South Wales, Australia, it is a white variegated form of 'Brunniana Aurea' that shows its variegation best when grown in light shade. z8





Cupressus macrocarpa 'Chandleri' Very dense and broadly columnar, striking in the landscape with a slightly irregular outline when viewed from a distance and is extremely wind hardy and salt resistant; grows about 50 cm per year; dark green foliage lays on an angle and swirls around the perimeter of the plant; an old time cultivar that originated in Chandler's Nursery, Hobart, Tasmania. z8
