  Lobivia ferox cv. TWIST CACTUSPEDIA       

 


L. ferox cv. Twist is a very odd cactus with long irregularly curled spines, sometime hooked to form ringlets.
 

Description: The standard Lobivia ferox is  a very large, spiny and very variable cactus, solitary or branched. The body is almost concealed by the spines.
Stem: Bluish-green, spherical at first and later sort of cylindrical, and it may grow 25 cm tall and 10-40 cm in diameter.
Ribs: 25 to 50 ribs deeply incised between the tubercles, which are approx. 2 cm long.
Spines: Radials are hard to tell from the central spines. Each areole bears approx 4 to 15 spines ranging from slender to thick, conical with a wider base, and irregular in length, the longest up to 8 cm or more. They are flexible and curved upward, and those on new parts of the plant have occasionally a hooked tip. Their colour varies from yellowish to brown when young, but later grey.
Flowers: Lateral or basal, 7-10 cm. long, funnel-shaped, and have a slender, curved tube covered with long white hairs. Perianth segments are short and white, but can be of almost any colour.
Fruits: Globular, dark green with flowers remnants. The fruit has a whitish mucilaginous pulp  and is edible with a fresh and agreeable taste.
Remarks: The cv. Twist is a strange and nice cultivar with very long curly irregularly  spines sometime hooked to form ringlets. With good sun exposure the spines are 10-12 cm (or more) long.

Cultivation: It is a summer grower species that offers no cultivation difficulties. Lobivia ferox has a fairly large tap root, and should be kept in a deep pot with a very draining mineral substrate. Water regularly in summer (but do not overwater ) keep dry in winter. Feed with a high potassium fertilizer in summer. Repot yearly until reaching about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter but can be done at other times. Do not water for a couple of weeks after repotting to reduce risk of root rot via broken roots. Repotting will increase size of stems. It is quite cold tolerant if kept dry (hardy to -5 C).  Need a bright exposure, full sun or half shade in summer.

Propagation: Grafting, cutting.
