Distribution |
Mexico - northern of Mexico City to
USA - California, Utha, Wyoming and South Dakota
very warm steppes |
Growth period |
sunny and hot, but some differences to respect
1. with green, less spined shoots, are easy to cultivate,
should be protected before blazing sun in spring, after flower a sunny location
2. with stronger spined shoots, are some sensitive for to much watering, careful pouring
get a full sunny location
permanent moisture avoid, first watering in March
than constant pouring, but first after drying soil,
constant slightly moisture, to form buds
in early summer many watering, in mid summer and early fall sparse pouring
from late fall to spring absolutly dry |
Winter period |
very light and absolutly dry minimum 6–10°C (42–50°F)
shrink of shoots is normal
some species are winter-hard and
are cultivate outdoor with some measures |
Substrat |
with some clay, nutritious and well porous |
