one of my cascade has gotten taller than me now, they weren't doing great until I got some drip irrigation set up, they just took off after that though. centennial are really starting to burst up as well, I'm starting to notice some lateral growth there. My lonely sterling is till only about 8 inches tall but it's looking like it will take off soon as well. only the 1 shoot on that one as well. but it was also the last in the ground so we will see.
