Echinocereus viereckii
A clumping hedgehog cactus from the Sierra Madre Oriental of north-eastern Mexico, with yellow-spined stems up to 20 cm and large purplish-pink flowers. It comes from a warmer, wetter, shadier habitat than most Echinocereus, so it wants bright light without harsh sun, summer water and a cool, dry winter.
Where it grows wild
Grows on rocky slopes in scrub and oak-pine woodland edges of the Sierra Madre Oriental foothills, often among rocks and leaf litter with some shade from shrubs.
Recorded at 200–1700 m, with a median of about 1225 m; most records are around Monterrey.
