Viereck Hedgehog Cactus.
"Viereck’s Hedgehog Cactus" from Tamaulipas, Mexico, offsets freely with some erect and some sprawling yellowish green stems to form a clump up to 30cm tall and which may eventually reach 60 to 70cm in diameter. Its splendid violet-pink flower opens wide, and lasts for several days.
Anderson 2001 recognizes three subspecies, of which my (Dalhousie) plants with their 8 or 9 ribs appear to be of subspecies viereckii The other 2 subspecies are subsp. huastecensis with more ribs and subsp. morricalii which is nearly spineless.
All of these need limey, rich soil, and much patience. Mine, which I planted in 1982, first bloomed in their 7th year from seed and they continue to do so annually in the Dalhousie greenhouse. all have the largest of my echinocereus blooms by almost a centimeter of diameter. Like E. adustus, however, E. viereckii has light, creamy yellow, or very slightly green-tinged stigmata. Only Anderson (2001) contains any mention of this plant which was discovered in 1934.
