Cintia knizei is a very rare small alpine cactus native to the high
Andes of Bolivia.
It is a solitary
dwarf, flat to globose cactus (in the
wild), that become cylindrical when it is grafted.
up to 5 cm in diameter; covered with large rounded
podaria. The colour can vary from olive-green to purple to
brown, depending on the time in the growing season and the amount of
sun and water,
The areoles are sunken between the podaria, and are woolly.
5-6 short spines only occur on juvenile areoles; adult plants and
pericarpel are spineless.
carrot-like, up to 10 cm long.
Diurnal, yellow 3-4 cm in diameter on the stem tip,

Elonged, dry with a thin pericarp, that remain for a long time
incorporated within the stem.
Seeds: Black 1,2 mm long 0,7 mm large, the surface is convex
Blooming season: in spring.
These plants come from
mountainous areas, so like bright light, cool and
dry conditions in the
winter; this is important for the
flowers as well as for their
health. Without this
cool winter period (0-10° C) they normally won't get many
buds. They have
taproot and are of difficult cultivation and
rot prone because of a great
sensitivity to the
excess of watering, not easy to get to any large size on their
own roots really a challenge to grow into a large
clump. They are commonly
grafted to avoid root problems and to make easier to grow.

It is very cold resistant as low as to -10° C or less for short
periods of time. It is a fine plant for a rock garden or container,
contrasts well with agaves, yuccas, and low-growing flowering plants.

On a graft the plants are easier to grow, but the body splits if
over-watered (especially in spring).
Propagation: Seeds, also can be grown from cutting or graft.
Seeds can be sown in the spring or summer. The seedlings should not be
disturbed until they are well rooted, after which they can be planted
separately in small pots.

Conservation status: Listed in
CITES appendix 2.
Taxonomy: This plant was discovered by the well known Czech
collector of cacti Karel Kniže in 1969, but not formally
described until 1996, by Jan Řiha.
Since the plant was different to all the known
Dr. Jan Řiha and Karel Kniže established a new
genus and named it Cintia, after the province where
the plant was discovered.
genus Cintia comprises only one
described (Kniže mentions three, but only one has been
described). This species was first distributed by Kniže as
n.n., but when it was finally
published it was named Cintia knizei.
The other name Knize used was Cintia subterranea while a
third was refereed to as Cintia
species nova. They all look the same. They also produce the
same type of flowers and even flower at the same time.
The small yellow flowers develop extremely fast. It is close related
