Opuntias grow with water, right temperatures, right soil and sufficent attention.
They show a remarkable abilty to come back from cold, scorching heat or neglect. But if you treat them well, they will surprise you with growth, flowers and some more growth.
Ex. Bob Smoley. Nice spined plant
I grow these plants in trays, they grow more natural this way
and are less sensitive to burning.
Small pads with spines that come easily loose. Not too painfull.
