No one knows for sure as the original source is quite young itself, less than 20 years old I believe and maybe closer to half that. Speaking offline with Arktrees, they capable of vigorous growth typical of a happy redbud so ultimate size may be around the species average but it's all a guess right now. They are also now taking selections from Rising Sun offspring and applying for patents. I found the following patent searching for 'JN2' which is the Rising Sun. John Edit: I read the patent and it was a branch sport on a Rising Sun growing in a field of RS liners, not a seedling that led to this new selection. It's trade name is Solar Eclipse and SoonerPlantFarm has it for sale HERE Here is a link that might be useful: Rising Sun branch sport patent This post was edited by j0nd03 on Tue, Aug 27, 13 at 12:31

Resin, you may be right about the "heat requirements" of T. canadensis, but like others here, this marks the first time I've ever heard this tree associated with heat. Here in my home state, it is present naturally in the relatively cool Northeast half, and completely absent in the hotter Southwest. The natural forest associates of T. canadensis are as stated by Pinetree30, and also include paper birch, Thuja occidentalis, Am. beech, white pine, and a host of other species that comprise the mixed northern hardwoods forest type. Strange and counterintuitive indeed. +oM

We have two that we planted in 2000 along our western property line in a bed that is raised above a seasonal Âdry creek bed. (man-made for the occasional really wet winters.) They get almost full day sun with a 6 ft. fence to the back of them, a 50ft. tall Western Red cedar to the south, a 60ft. Douglas fir to the north and open lawns to the east. Our soil is sandy/loam. In summer, they are watered via underground sprinkler system; each has a Âbubbler head near the trunk. They are approximately 15 ft. tall now and almost as wide. We bought them for their wonderful leaf color, but IÂm not as impressed with their fall color, which is rust red. But I will say that the fall color is certainly a nice contrast to the many gold/yellow colors of surrounding trees. I have seen pictures of the wonderful blossoms on these trees, but all my redbuds (besides the two Forest PansyÂs, I have three green Cersis and a Cersis Chinensis) only have fuchsia buds in spring that open into insignificant flowers. The leaf shape and color and the interesting tree shape (more rounded) more than make up for the lack of appealing flower and fall color. Enjoy! S.

IME: Most established trees and shrubs can survive a certain amount of browsing from deer. I'm sure there's exceptions especially in an area with high deer populations. When I lived in the wild woods, deer would pick on a certain tree along the trail and make an effort, every time they passed, to stop and clean off any new growth that was present. I had a bur oak that was 3ft tall and 4" caliper, out away from the house that never progressed because of that. I never checked it in the future to see if they had eventually killed it or not. My Abies balsamea was a woods 'rescue' that looked pretty tough when I found it, from deer constantly browsing on it. Now in town, I notice a few branch tips 'nipped' on my Korean Maple last spring and a few branch tips nipped on the winterberry. But I have since placed deer deterrents out, hopefully to prevent them from making return visits, so often that they overwhelm things. So far so good. ;-)
