This prickly pear at Mom's has gone a long way from a few pads to GIGANTOR - CACTUS KING. It will be trimmed this winter back to a few pads. All the thick, woody parts will be gone. I was impressed by the length of this spine - a good 6 or 7 inches.
This barrel cactus at the DBG has all long spines. Pretty cool looking in my book!
