Dear Friends, Recently a friend called to tell me (rub it in) that his Tecophilea were just emerging from winter dormancy. He lives just outside of Wichita KS however and this seems very unlikely. His bulbs are growing near a concrete side walk ( a heat sink) and have survived through 3 winters. I just never thought Tecophilea might survive this far north. Just how hardy are they? How cold have they survived outdoors for any members? Do I dare try them here in Zone 5/6 in the ground? Best Jim W.
