It gets a ring of pretty hot-pink flowers in spring if it receives cooler temperatures (45 to 55°F) in winter. Water when mostly dry. ... well, organ pipes! Give this cactus full sun and water ...
Woody plants survive freezing temperatures by suppressing the formation of ice in living cells or by allowing water to freeze in plant parts that are not affected by ice formation. The common mechanism for woody plants to survive down to –40 °C (–40 °F) is supercooling. Woody plants that survive lower temperatures are dehydrating their ...
Pediocactus simpsonii, known by the common names mountain cactus, snowball cactus, and mountain ball cactus, is a relatively common cactus that has adapted to survive in cold and dry environments in high elevation areas of the western United States. It can be found at higher elevations than any other cactus in North America.
