Thank you for your comments,
@Hamwild and
@KellyFW. Both canadensis or occidentalis are apparently fine in this area, although when I searched this a few weeks ago, I was actually leaning toward Chinese Redbud (C. chinensis) based on the leaf shape. There is apparently one at our BioPark botanical garden, which only recently re-opened, so I've been meaning to go take a look. I also just discovered that a friend who brings me fallen leaves every year has a redbud on his property and I'll bet that's how the seed arrived in my yard. When he returns from out of town I plan to ask if he knows what he has.
I didn't mean to hijack this thread.
@IJsbrandtGA are you still there? We're all pretty sure you have a redbud!
