Hi, I live on the Isle of Skye and planted a red hot poker over 2 years ago towards the end of summer. The ground is well drained but not sheltered, but nothing happened, although it didn't die. The leaves grew slightly over 2 seasons, but thats all. I'll mulch round them this winter, and also note the advice not to cover the crown. About 4 weeks ago my wife came home with 2 more plants in small pots, with leaves about 9inches high. I had decide to keep them in the pollytunnel over winter, water occasionally, and plant them out in spring. Is this the correct procedure. Thanks, Steve
