Description
Austrocylindropuntia subulata is a tree-like cactus with a trunk and numerous cylindrical branches with rhomboid to ovate tubercles in a few spiral rows. It can grow up to 13 feet (4 m) tall.

How to Grow and Care
Though the large variety of species within the Opuntia genus means different Prickly Pears may need slightly different care, all are desert cacti requiring lots of sun, light, and very little water. So if you live in a hot, arid area, these plants can generally be planted outside, left alone, and enjoyed.
As desert cacti, Prickly Pears require maximum sunlight to thrive. Therefore, they should be kept in direct sunlight whenever possible. Very little water is needed. These drought-resistant plants grow best in hot, dry areas, and excessive water could cause them to rot. Hot temperatures are best, but these cacti will tolerate a wide range of temperatures. The most important soil requirement for Opuntia is that it drains well. Besides that, basic potting soil is fine, and these cacti will also grow in rock gardens.
Though Opuntia will grow just fine in a garden, they can also be grown in pots. To repot, ensure the soil is dry, remove the pot, and knock away the old soil. After treating any cuts with fungicide, place the prickly pear in a new pot and backfill it with potting soil. As with a new cutting, ensure not to briefly water a newly repotted prickly pear to avoid rotting its roots.
