Hardy Succulents

I attended my monthly Master Gardener meeting this evening. The speaker, Kelly Grummons, is an authority on cacti.  I was amazed by this interesting fact:  Cactus are only native to America.    Even in Zone 5, there are many  hardy cactus that are just as beautiful in the winter as they are in the summer, and most are evergreen.  When I plant new beds, I try to  incorporate some plants for winter interest, but until this evening, Cacti never crossed my mind.  His website: coldhardycactus.com
