Dexenthes, that's kinda funny that you would need a heater for highlanders, especially for villosa, when most people are having cooling issues with the plant. But with you living in Alaska, you should definitely give this plant a go, whenever you get a chance to. You should have no problem providing the necessary cooling. We live in hardiness zone 3, and i have been able to cool mine down sufficiently at night for some decent growth over the last year or so. Good luck with your (hopefully soon) future villosa.
