Instant desert effect. Growing in stacks of thick, fleshy green oval pads covered in a range of different sized spines, this Opuntia produces amazingly crystalline looking yellow or magenta flowers, followed by the famous, edible prickly pear fruit, standing upright on the edges of the pads.
May be worth trying planted outside in a raised of extremely free draining soil, if given a temporary winter rain shelter. Great in pots for the summer if moved into a frost free conservatory.
Easy to grow with occasional summer watering and kept dry in the winter.
