Where and how to grow Southern Catalpa trees?
I received seeds of this tree and got excellent results by winter sowing them. They are growing very fast and I have repotted them up into gallon size pots.
We live in the mountains, 1700-1900 elevation and I'm hoping I can grow them here.
Can someone tell me more about this tree? Does it need sunshine? How tall and wide and is it fast growing?
Thanks in advance for your help.
