Spiny Dunce Cap (Orostachys spinosa)

Native to the harsh steppes of Siberia and Mongolia, Orostachys spinosa forms striking, symmetrical rosettes of glaucous leaves tipped with soft, harmless spines. In late autumn, it sheds its outer foliage and contracts into a dense, spherical dormant globe capable of withstanding extreme sub-zero freezes. While monocarpic, the primary flowering rosette perishes only after producing abundant basal offsets to perpetuate the colony.
