atroviridis var. atroviridis
This species has showy dull-white or brownish blooms,
tannish-green stems and long thin spines.
Solitary cactus with showy dull-white or
brownish blooms, tannish-green stems and long thin spinesthat are not

Eriosyce atroviridis (atrovirens)
Eriosyce crispa ssp. atroviridis var. atroviridis (F.Ritter)
Origin: Chile, Atacama (Vallenar and Freirina )
Habitat: It grows in
costal areas where very little else grows. It's a very drought tolerant
species. Despite the lack of rain where it lives, the
extreme aridity is attenuated by the frequent, often dense, coastal
fogs. The fog tends to concentrate in the form
of a cloud band at an estimated height of 500 to 850 m. It
shows a recurrent pattern; usually it
is overcast in the early
mornings, the clouds dissipating during the late morning and returning
during the late afternoons. The plant grows often buried in the ground
and is almost impossible to spot without the flowers.
Conservation status: Listed in
CITES appendix 2.

growing cactus is kept for the beauty of its form
and flowers. It is a
summer grower species. Easy to cultivate but somewhat
rot prone if kept in a non
ventilated place. Require a very
fast draining drying soil, water regularly in summer,
but do not overwater.
full sun exposure, but
must be protected from excessive heat and sun in summer, and seems to do
best in cultivation with a bit of shade.
Good heat tolerance.
Keep warm and dry in winter (5 to10°C)
to avoid rot. Not highly tolerant of a great deal of frost. (Frost
tolerance -5°C or less for shot periods)
Usually propagated from Seeds.
