Ariocarpus Scheidweiler (1838)

(Greek "aria" = whitebeam, "karpos" = fruit)
or perhaps the formation of false greek erion = wool,
because the fruits appear from the woolly hair of the plants
oblate, bulging, with a thick beet root, gray-green to green
areoles tiny spines absent, flowers from the axil wool

north - Mexico
USA - southwest - Texas
warm arid regions

Growth period

full sunny and a warm location, very sensitive to too much moisture, keep the root neck dry
moderate watering, only from below and not in the woolly crown
from mid of July to mid of August is a summer rest period prefered
in this time keep the plants complete dry, this furthers the flower formation
the main growth period and flowering time is in fall, then a little more watering

Winter period

completely dry and cool in 4–8°C (39.2 to 46.4°F)


very porous, pure mineral, sandy-loam
with the addition of limestone gravel, pumice, granite crumb, expanded shale, quartz and pebble tiles
addition of gypsum fertilizer in small amounts is good
