I have a cactus which has been with us for some time now and it has reached a good 2ft in height. It is a trio of tall 'spikes' which are covered in prickly,hairy needles and they are a * if you catch your hand on them. My wife does this on a regular basis when closing the curtains. I have no means of sending a pic yet,but wondered if anyone had an inkling as to what this type of cactus this might be
