Austrocylindropuntia subulata – Eve's Needle Cactus

With its long, pointed leaves emerging from cylindrical stems, Austrocylindropuntia subulata is an unusual cactus that adds height, texture, and intrigue to any collection. Though it’s closely related to the classic prickly pear, this species has a much more upright, branching growth habit and narrow, leaf-like projections that give it a prehistoric feel. Fast-growing and architectural, it thrives in warm, sunny spots.
