Radial spines: 9-15 or so, thin, whitish grey or yellow with

Central spines: 3 or 4, very similar to the radials. One of the
centrals appears longer than all others, and and may occasionally be more

Flowers: Small, funnel-shaped, apical, golden yellow to

remain for a long time on the plant body after blooming.
Blooming season: Spring to summer.

required when growing various Parodia species from their small, slowly
germinating seeds, some of which take as many as two years to germinate.

these plants regularly, and fertilize with a low nitrogen fertilizer
every 6 to 8 weeks, from mid-spring to late summer. This plant should
remain rather dry at other times (especially in winter), except for a
quick, periodic misting on warmer days in late winter. If it is kept
absolutely dry for a long period, it tends to lose its roots in winter.
It can tolerate light frost (- 4C°),
but rots easily if wet and cold.
If the local climate is warm enough to grow this plant outside, be sure
that soil is well drained and sun if full, but with protection from
strong midday rays.
