Lynn,
That planter is about 2 and a half feet tall. The planting mix goes all the way to the ground, so plenty of room for root growth. He had to be clever to make the serpentine shape around the flower bed and the tree. He used a molded plastic length of material that you can get to make curved areas on decks, for the inner supports to attach the wood uprights to. (And the poor guy had to build it twice!)
I'm happy to hear that your Red Bud is doing well. The Golden Chain tree is thriving!
I still haven't taken the cuttings of the Sedum yet. I'd better get to it soon though, huh? I have so much stuff waiting to be planted too. We did get a lot of time consuming odds & ends stuff done yesterday, so maybe I'll be able to get a bunch done today. Depends on whether my son can find something to keep himself occupied with I expect.
Hope you have a fine day & I'll yap at ya later.....
