Nopal cactus growing at the Orchard. Copena V1 and F1 have different shaped pads, different flower and fruit colors. Q. I’ve been having a difficult time acquiring these two varieties of nopal. Do you know how I might find them? A. They are not really varieties but selections. Varieties in the horticultural sense meant to be cultivated varieties. I have them at our facility in Las Vegas but they would have to be propagated from a couple of pads. The only other source I know of would be in Hermosillo, Mexico. You could try contacting Everardo Zamora at the University of Sonora, Hermosillo, Mexico, but getting across the border into the US might be a bit difficult or time consuming. Everardo Zamora ([email protected]) There are other selections/varieties available online that you could look at being grown in southern California and Arizona. There are some with some huge tunas (fruits) that are very eye-appealing but I have never grown them, only the Copena’s which are grown commercially in Sonora.
