Not sure why this is called Rose Quartz, but that's what we were told. This globular, offsetting cactus could be in Parodia, Lobivia, or Echinopsis, depending upon who is cutting the cactus cake. This cultivar has mound-forming stubby light-green stems with raised tubercles and whitish-brownish spines. The flowers are large and orange. These plants are rooted offsets in 4-inch pots.
