Oh, I DO have the ornamental kind growing in pots in fresh potting soil! And sometimes some of the other will come up in my veggie garden, but never does very well. And elsewhere on my place, it won't even grow at all. My place is not a good location for certain plants. Especially since all the years of drought. The water here is not very good and I think during droughts stuff from the irrigation water builds up...and until we get some good years with adequate rainfall, it won't get flushed out...at least, that's my theory. Other plants do okay in spite of all this, as long as they get a little water.
