About Missouri Foxtail Cactus
Escobaria missouriensis · also called Missouri Pincushion, Nipple Cactus · houseplant
Missouri Foxtail Cactus is a small, cold-hardy, globular North American cactus native to the Great Plains. It produces cheerful yellow to greenish-yellow flowers in late spring, followed by red berries. One of the hardiest cacti in cultivation, it tolerates frost down to about -20°C with dry conditions. Not toxic to pets.
Preferred mix: Very gritty, sharply draining cactus or rocky soil mix
Watch for — Root rot in winter: The commonest cause of death. The plant must be kept almost completely dry when temperatures are low. Soggy winter soil = rot. A gritty mix and minimal winter water is the best prevention.
Why missouri foxtail cactus needs this mix
Missouri Foxtail Cactus is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Missouri Foxtail Cactus is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
