Not being familiar with the life cycle of cacti, I had three theories:
A. They are seed pods.
B. New needles are grown yearly.
C. They are genetically engineered needles.
If you picked C, you would be correct. The needles of this commercially grown cactus are engineered to stay soft and rubbery until they fall off! Makes one ponder for a moment the powers of man, doesn't it?
