Ok. I will keep an eye on them for another month and post more pics in July or August.
Of course, if by August, they are six feet tall and growing, we'll know they are Truly Something Else.
Meanwhile, I'm floored about how fast they are growing. They are passing everything I have. I'm surprised they aren't making vroom noises and bothering the neighbors. (Six weeks or so out of the shipping box and they are taller than, though not as thick as, the "Truly Tiny" I bought last year.)
