Notocactus

Synonyms: Parodia
Family: Cactaceae

Originating from Brazil, Uruguay and Argentina, these popular cacti are mostly globular in shape, though a few are column-shaped. They have distinct, often notched, ribs and varied spines. The self-fertile, diurnal flowers, which grow from the top of the plant, are funnel-shaped, with red or purple stigmas. The buds and fruits are woolly. Still generally sold as Notocactus, botanists now include this in the genus Parodia (see entry at Parodia).

Species

N. concinnus is a small, tubby cactus, with deep yellow flowers.

N. herteri, prized for its hot pink to purple flowers, is squat and must be about tennis ball size before it will flower.

N. leninghausii is a columnar cactus that may grow to 90 cm (36 in) high in ideal conditions. It has large, yellow flowers.

N. uebelmannianus is another squat grower, generally with large, purple flowers although there is a yellow-flowered form. All species are slow to produce offsets.

Cultivation

These mostly small cacti are easy to grow but need an intermediate greenhouse or conservatory in frost-prone climates. Grow in pots of well-drained cactus compost, available from good garden centers. Provide maximum light (but shade from direct strong sun), and a dry, airy atmosphere. Apply water in moderation during the growing season and keep dry in winter. Propagate in spring from
seed germinated at 21°C (70°F)

Climate

Warmest parts of zone 9 and above.
