Don't you just love it when there's random flotsam hot-glued to your plants? I really don't know why they do this to cacti and succulents. This plant is bizarre enough on its own, it doesn't need a silly flower to catch your attention. I especially love the hot glue tendrils that they didn't even bother to pick off. In any event, I promptly pried off the flower once I got home from the store.
This is my new Opuntia subulata that I picked up at Home Depot for $3.48. It appears to be thornless and has weird "leaves" growing out of the stem. After looking up information on this plant, it looks like it might develop needles later on in development. I guess, we'll wait and see.
Here's the label on the pot, although I couldn't fit it all in one photo:
