Distribution

USA - California, Utah, Nevada, Arizona, New Mexico, Texas
Mexico - to Oaxaca
very warm steppes

Growth period

full sun exposure and very hot, during the summer also outdoors
for a strong and colorful spination is many direct sun exposure necessary
watering only if the soil is complete dried, then permeating watering
plants in pots to 5.9 in (15 cm) benefit of a repotting every 2 or 3 years
this genus is somewhat sensitive to too much water and grows very slowly

Winter period

bright and dry at 41–50°F (5–10°C)
some species warmer at 53°F (12°C) to prevent cold damages
e.g. F. flavovirens, F. latispinus, F. glaucescens, F. recurvus, F. robustus

Soil-mixture

pure minerally and very permeable to water
