Taxodium, Swamp Cypress 'Nanjing Beauty'

I got this cultivar because it lacks knees, the lawn-mowing nightmare. I had first seen the tree in China where it is used by the thousan...Read Moreds to stabilize new land built by dredging in the Shanghai area. My only complaint is that it seems particularly susceptible, at least in my area, to the cypress gall midge.

.This tree is worth having if only for its unusual
origins. It is called Nanjing Beauty and, not surprisingly, comes from
...Read More China, the Nanjing Botanical Garden to be precise. It is a Bald
cypress, but a hybrid of two different North American species; Taxodium
distichum, which is the Bald cypress of the North America; and Taxodium
mucronatum, which is the Montezuma cypress native to Mexico. Hybridized
in China and named Taxodium 'Zhongshansa' it was selected from
thousands of candidates for a new street tree for China and it has now
been planted in the millions across the south of that country. But,
despite its popularity in China, it is still exceedingly rare across
most of the world, even in the North American homeland. But in addition
to its unique origins, Nanjing Beauty has some wonderful
characteristics, possessing all of the advantages of the parents and
none of the disadvantages. It is deciduous and has the feathery soft
needles, the rich russety autumn color, the straight as an arrow
conical shape, and the rapid growth-rate, which is at least 16 feet in
10 years, likely more in warmer regions. But it's what it lacks that
makes this beauty such a winner. It doesn't make knees, the woody
out-growths that are so problematic to lawn maintenance. At last a Bald
cypress without knees.
Nanjing Beauty has tremendous adaptability as well, tolerating high
alkalinity, drought, periodic flooding, and extreme heat and cold. It
will eventually reach 70 feet, or more, in many, many years and take on
the tiered silhouette of a mature Bald cypress, which is rather grand.
It is disease and insect proof and a superb choice for fast screens or
soil stabilization and it makes a ideal specimen choice. It will grow
across the most of the United States, the warmer parts of the UK and
New Zealand and is a splendid choice for Australia.

I am about to plant two of these trees, which were given to me by a friend. I am wondering how they will fair in Perth's very dry summer heat.
