Hi Pam and Dennis, Pam, welcome to PBS. It's a great group. OT Cacti: Dennis, I grow some cacti outdoors here in central Indiana. I have a feral Opuntia (not humifusa, maybe phaeacantha) from northern Indiana, some O. phaeacantha from my niece's neighborhood in Centennial, Colorado (a suburb southwest of Denver), and some tiny little things from High Country Gardens. The tiny ones include Escobaria sandbergii, Escobaria sneedii, Escobaria vivipara bisbeana, Opuntia whipplei, Opuntia viridiflora, Pediocactus simpsonii, Echinocereus coccineus, Echinocereus reichenbachii caespitosus, and Echinocereus viridiflorus. The latter are currently undergoing their first winter outdoors in Indiana. This is therefor an experiment, not a gardening recommendation. There are some pretty hardy cacti around.
