Pilosocereus azureus
Woolly Blue Spires
Description
Stately spires of dramatic blue reach skyward, graced with margins armed of golden spines and a soft, downy fur. The spectacular sky-blue color of this skin is surprising to say the least in a world of green expectations. For this reason, it is a great color contrast as well as vertical accent in the landscape or large container. Growth rate is quite fast for a medium bodied cactus plant, up to 1 1/2 feet per year. Can grow up to 12 feet tall and branching both from the base and mid-body. Full sun; ample watering and fertilizer during warm growing season; excellent in hot inland deserts as well. Hardy to mid 20s.
