Opuntias All Look the Same

It’s not really true, but it seems true.

One of my neighbors has a small planting of various kinds of Opuntia cacti at the end of his driveway, and at some point I should go down there and take pictures to show you how much Opuntias can differ from each other, but today I’m just talking about the ones on my property. Mine are boring, and they all look the same (to my grossly uneducated eye). And there are thousands of them.
