Thanks for firming up my initial impression. Looked into Albizia julibrissin seeds after hearing of Caroltropicals' experience and found they're known to remain viable in dry storage for nearly 150 years.... so imagine a mere 10 or 20 in well draining soil is not unreasonable. The spot is in a corner of a long alley that has always collected a lot of windblown tree debris, such as leaves...... or seedpods. Am guessing I disturbed a seedbank when I removed the mulch and turned the soil in a multi-season effort to eradicate running bamboo that finally found its way in from the adjacent yard. Thanks again for the inputs.

Mine is a Wilson too. Planted bare root spring of 2013 as a 4ft or so single trunk. Died to the ground after our awesome winter in Chicago (no winter protection), but came back pretty well. Starting to color a little, but it seems like it's almost still growing with the rain and cooler temps we've been having. I seem to remember it turning yellow last year about the same time the Ginkgo did.

Mimosa wilt has been reported in California, notably southern CA, though the lack of characteristic symptoms noted in the OP makes this less likely. I'd avoid any cultural changes that might accelerate the tree's decline. As for planting A. julibrissin anywhere where significant disease problems have been reported, it would be best not to give the tree a prominent location, and to accept that it might have a limited life span (someone living about a half mile away from us had a huge old tree in their front yard that went from magnificent to dead over the span of three years). I have two specimens of "Ernest Wilson" grown from seed started three years ago, planted in two out-of-the-way locations. Both survived -9F this past winter with virtually no damage. There are cultivars i.e. "Flame" and "Union: which are said to be wilt-resistant. As for invasiveness, in my part of Kentucky I don't see self-seeded trees growing along roadsides and in "waste places" as described further south.
