Thank you for asking --did they come up?
These are Ebenopsis ebano, Texas Ebony -- formerly known as Pithecellobium flexicaule, according to Brooklyn Botanic Garden's Growing Bonsai Indoors, 2013 edition. (A helpful book, as I'm new to bonsai and need to hedge my bets with species that are likeliest to tolerate my climate and my care...I like Texas Mahogany. Saw some Mahogany (not Really mahogany which is tropical I think) inColorado and thought it would be a beauty as bonsai. But I think it grows slowly. Haven’t seen any place to buy a bush.
I just enjoy working with the trees and shrubs to grow just literally "little trees" I also work with a tree that here is called hackberry , manzanita, createsolid brush ,mountain mahogany, Palo Verde.
Here is another of the three cercocarpus species:I believe this is the “mahogany “ I saw in Colorado, mountain mahogany. https://blog.twoknobbytires.com/2008/12/11/true-mountain-mahogany-cercocarpus/
Best wishes for a happy & hardy little tree!Haha! I bought one mail order from a Garden center in Colorado, but very young. Three little tender limbs. Maybe should take a pic and post for the native tree contest. Doubt it will make it in the Philly climate tho. Somehow thinking it will succumb to a fungus away from its desert air.
Based on growth this summer i will be lucky if it reaches “pencil in pot” stage this decade. Haha. Also is not native within 200 miles of Philly. But I couldn’t resist. And above the string is a sacrifice branch. Haha again!SO little. View attachment 390630
