I don't know if you remember that thread I posted years ago in DG about the two tiny toothpicks Heirloom had sent me. I posted pictures of them next to bands from Vintage Gardens to show how pathetic they were. One of those toothpicks was Kaleidoscope. Now, five years later, it's still only about a foot tall, but I blame that completely on Heirloom because the Kaleidoscope bushes at Garden Valley Ranch are between three and four feet tall.
The other Heirloom toothpick was Gloire de Dijon, which finally started growing after about three years, but turned out not to be Gloire de Dijon.
