The listing, unusual cactus - pine cone cactus has ended.
Paper Spine Cactus.
Tephrocactus articulatus var. papyracanthus, Paper Spine Cactus. Also Called: Pine Cone Cactus, Spruce Cone Cholla, Opuntia papyracantha, Tephrocactus papyracanthus.
This is a very interesting plant looking like spruce tree cones. Good for xeriscapeing. Has white flowers.
A harmless cactus with wide, paper - like spines. But, the little fur-like spines at the base of these larger spines can stick you, so use gloves if you handle this plant.
It is made up of small pine-cone shaped segments and it is very fragile at each segment. Easy to propgate from the segments. Closely related to the much hardier pine cone cactus.
