I wanted to mention something else about the (Spring Cactus or Easter Cactus)Rhipsalidopsis.
I decided I would like to propagate and sell them, so I found a grower who advertised several different colors. Price was perfect so, I ordered them, and when they arrived they were beautiful healthy plants, but much to my surprise, they were all patented. Not with the normal PP we usually see, but with a statement that said For decoration only, do not consume. Propagation prohibited. I thought about it awhile and then I called the grower. it seems he did not actually grow them, he shipped them in from Woodhill Greenhouses in Lynden, ON Canada. So, I called Woodhill. They are definitely patented. My point here is, that I think anyone propagating and/or selling these plants should advertise the fact they are patented if in fact they are, so others do not waste time and money and space on plants they can not reproduce, if that is why they purchased them.
Now you all know my pet peeve. I wanted to share that experience with you so you are aware that there are people out there who will not tell you the plants are patented. I worry about reproducing patented plants all the time. That is one reason I usually try and purchase from someone who will not withhold that information just to make a sale.
