This species is quite variable, and now includes many forms
(previously considered independent species)
|
|
Description: Usually solitary.
Stem: Bright or dark green, globose to short cylindrical, up to 20
cm tall, 15 cm in diameter. The apex is depressed and filled with
whitish-grey wool.
Ribs: About 12 to 22, at maturity well marked and sharp, with
scarcely prominent chinned tubercles. The crest of the ribs typically
turns a purple red colour in full sun.
Areoles: Well spaced, woolly, recessed, 15-20 mm in diameter.
Radial spines: 4 to 10 (-12), yellowish, sturdy, about 20 mm long,
curved down or backward.
Central spines: 0 or 1, slightly heavier but not very different
from the the radials.
Flowers: Lemon yellow with glossy petals (sometime shaded with
pink), up to about 4-5 cm in diameter, and standing near the top,
decorated with about 8 to 10 red pistil lobes which emphasize the yellow
of the petals. The buds are tomentose.
Blooming season: They bloom annually around July.
Fruits: Fleshy reddish to purple, about 10 mm long.
Seeds: 1 mm, long, black.
NOTE: When the plants become older they look quite different from
the juvenile forms, and this is evident when we can observe a seedling
growing next to an older plant - the younger plant is smoother and the
older plants have ribs and tubercles - one would almost think they were
different species.

Cultivation:
It is easy to grow. They like a warm, bright location,
and do great in
partial shade (avoid full sun). They need good drainage, and prefer a
neutral to slightly acidic compost with plenty of extra grit.
Water and
feed during the summer. Best if watered with rain water.
Keep above 0°C
and rather dry in winter. It rots easily if the substrate is wet and cold,
and tends to lose its roots in winter.
Propagation: Seeds

and Malacocarpus have recently been transferred to genus
Parodia, so the names of several plants previously
accepted are now all synonyms of Parodia sellowii.
