Coryphantha cornifera originates mainly in the Mexican states of Querétaro and Hidalgo, south to the Valle de Mexico, north to Guanajuato and sporadically in San Luis Potosí. 

Common name: Rhinoceros Cactus

Stem: Flat globose to cylindrical, up to 8-15 cm in diameter, 6-12 cm tall, dull olive-green, apex depressed, with a blunt, depressed apex covered with e wool.
Tubercles: Tubercles are spirally arranged in series of 5 and 8. Conical, rhomboid at the base, obliquely cut, grooved above; on new growth the groove may show some felt. Basal diameter 12-16 mm, 8-14 mm tall. Axil at first woolly, then naked.
Areoles: Oval, 3mm long, 2,5 mm wide (when central spines absent), round 2 mm Ø (when central spine present)
Radial spines: 10 to 20 fairly stout, pale whitish, yellow or horn-coluoured, sometimes darker tipped, 0.9-1.6 cm long, horizontal, irregularly radiating, interwoven, needle-like, straight or slightly curved; in youth pectinate. Occasionally 3-4 thinner spines, more densely set.
Central spines: 0 or 1( to 3), dark brown, becoming grey from the base, subulate. The dominant central is straight, porrect, or curved downward, usually about 1 cm long, but it may be longer on older plants (up to 1,8 cm); the other two protruding laterally, and curved.
Roots: Fibrous root or semi-taproot.
Flowers: Very big, 5-7 cm wide, yellow (occasionally red), funnel shaped, 6-7 cm. The linear segments are lemon-yellow, sometimes red at the base. Filaments reddish to reddish-yellow. Anthers yellow, stigma pale yellow, stigma lobes whitish.
Fruits: Green, juicy with attached flower remnants, 20-25 mm long, 10 mm wide.
Seeds: Reniform (kidney-shaped), brown, 1,3 mm long.

Cultivation and Propagation: In culture C. cornifera is without problems, and regularly shows its large yellow flowers. It does best in slight shade, but does well in full sun too. It is sensitive to overwatering (rot prone), and needs a very porous soil with good drainage. It flowers quite early, but needs about 8-12 years to reach the typical, definite outlook. It tolerates fairly low temperatures as long as it is kept dry (hardy to -5° C or less for short periods of time).

Lovely cactus

This little gem arrived quickly, safe and sound, well-packaged. It looks very healthy & I can hardly wait 'til spring to see if it blooms.

Planet Desert Experience

I am relatively new to Cacti. But already my collection is into the hundreds. I have bought from a number of online retailers, local sources, and propagated from seed and offsets. While planet desert prices are slightly higher than many online retailers, their quality has been excellent and their packaging superb. I so appreciate not having to clean sphagnum and perlite from between tight Cactus spines. I highly recommend planet desert for their quality Cacti, excellent packaging and shipping, and their great selection.
