Small tree will arrive next week. I'm excited to see what it will do in our climate. It was so lovely in Colorado. I'm hoping we do not receive too much rain for it... We get between 30-40" per year.

"Purple Robe TM" is the trademark. Cultivar names cannot legally be trademarked. What this taxon's cultivar name seems to be a mystery.
Described as thornless, but it's been said that some specimens develop thorns.
It isn't invasive in the US southwest. Commercially propagated stock are likely to be grafted on seed-grown R. pseudoacacia understock. The understock is invasive when grown outside its native range in eastern and midwestern North America, and is prohibited in Massachusetts.
I have two trees in different areas on my farm in SW Michigan. They are beautiful compact trees, with wonderful smelling flower clusters ...Read Morein late spring. Young branches are covered in red hairs, approximately 1cm long. They look like they would be sharp as a cactus needle, but they aren't. They are very unusual and great to look at year round. Both trees are in partial shade, which I think may be key to containing their growth. Neither of the ones I have are aggressively propagating whatsoever, so take others comments with a grain of salt, your results may vary. The two on my property have been there for at least 20 years that I know of.
I have not grown this tree for myself but I want to. There are 2 of the purple blooming ones and 1 white blooming one down the street fr...Read Moreom me. One of the purple blooming ones is severely damaged and sick looking. The other 2 are on the same property but very healthy. Over the years I have never ever seen them sucker. That is a big plus for me. Nor have I ever seen new seedlings from the dropped seeds. They are growing in a spot on this property that is clearly seen without trespassing. I love the look of the large snapdragon type blooms and I love the smell of grapes they put off. Now that I know what they are, I can do research on them and get me some! They do seem slow growing however.

NO way is this invasive here.. in fact, I have never even seen it sucker here. One of the most attractive trees that one can grow in sunset garden zone 11.

Even though we dug it out 2 years ago, I am constantly cutting off the new shoots it is sending up, apparently from the roots that weren't dead? I would never plant this tree again.
