Mine are about 6 feet tall but they are suffering. I've got them shaded and they get about 15 minutes of water a day. I just hope they survive this year.
Here's a shot from early June.
I also have about 8 bines growing in the Christopher Creek Area.
The best time to pu them in the groung would be as sson as you can get the rhizomes in April.
BTW: I'm on the mountain side of Baseline across from Lowes.
