@jeatacake, you do need the right conditions to grow them Jeff. We have the ideal conditions here in central Perthshire. You need a well drained soil in a shaded area with moist conditions, and not too hot.
Wowsers! Looks really good 👍🏼Love these and trying to grow one myself. All good so far although I noticed somethings having a nibble on it. I will probably cut off any buds I see this year to let it establish.
