During a conference on poisoness plants back in spring, a clever botanist brought up a list of plants that had terrible sounding names. On a random stroke of luck, I discovered the name of an unknown cactus growing in my garden that was there before we moved into our home. For years, it has grown on the hot west side of the home. I thought the plant was cool looking so I just left it there. Now I have a name for it....Opuntia Molesta!!
