Summary
| Description |
Part of the private collection of cacti at Manor Nursery, Angmering Wikipedia - Silver torch cactus (Cleistocactus strausii) is a succulent of family Cactaceae. It is native to high mountain regions of Bolivia and Argentina. Its slender, erect, grey-green columns can reach a height of 3 m (10 ft), but are only about 6 cm (2.5 in) across. The columns are formed from around 25 ribs and are densely covered with areoles, supporting four yellow-brown spines up to 4 cm (2 in) long and 20 shorter white radials. The cactus prefers free draining soils, strong sunlight, but not high temperatures — in fact it can withstand hard frosts down to -10°C. In its natural habitat it receives plenty of water during the summer, but almost none over the winter. In cultivation, watering too much in winter often leads to root rot. Older cactuses, over 45 cm (18 in) tall, produce deep red, burgundy, flowers in late summer. The 6 cm (3 in) long cylindrical flowers protrude horizontally from the columns. In common with other cacti in the genus Cleistocactus, the flowers hardly open, with only the style and stamens protruding. Cultivated plants often flower freely. |
