Espostoa Melanostele | Peruvian Old Man Cactus
This cactus is found near the equator in Peru. It grows at high altitudes. This cactus can be found in the lowlands on the western slopes of the Andean Cordillera, in thorny dry matorral nearby to Browningia candelaris. Espostoa melanostele is a summer-grower and an easy cactus to grow. It makes a great potted specimen.
Espostoa produces noticeable amounts of growth each year if kept well fed and watered throughout the warmest months, particularly if it has been acclimatized to accept full sun. Once this cactus is established it can easily produce 20 cm of growth every year. Most plants will offset readily, and clumps can be produced in a few years. It will fill a large pot in time however, so space is needed if it is to show of its best.
