Morning Cloud cultivar (Chitalpa tashkentensis) a cross between Catalpa/Catawba and Desert Willow

2010-8-28 - Greenville, Augusta County, VA
Technically not a tree growing in the wild, but a cross between Southern Catalpa (Catalpa bignonioides) and Desert Willow (Chilopsis linearis) both from the southwestern US.
SNWA (Southern Nevada Water Authority) has this to say:
Chitalpa was hybridized in 1964 in what was then part of Russia, but is now Uzbekistan. It is a cross between the Desert Willow (Chilopsis linearis) and the Southern Catalpa (Catalpa bignonioides). May begin with an open, irregular shape, but matures into a dense, spreading crown. It has the larger flowers of the Catalpa and the flower color of the Desert Willow. The foliage is lusher, like the Catalpa, but long and widely lance-shaped rather than heart-shaped. More drought tolerant then the Catalpa. More cold tolerant then the Desert Willow, but also less heat tolerant. Susceptible to sun scald and windburn. Best with some afternoon shade and protected from our hot desert winds. Suckers quite a bit at the bottom of the trunk. Interesting peeling bark. Synonym: x Chitalpa tashkentensis.

Update 6/18/15: What prompted me to move it here was that Deb said in a recent eMail that caterpillars almost did it in last year but that the tree is recuperating this Spring. Naturally, I'm wondering if it's the Catalpa Sphinx moth. Maybe someday she'll send a picture of the worm! -- One source I read (which I can't relocate at the moment) states that this tree doesn't make seeds, so perhaps there's no need to worry about it becoming invasive.
