Mammillaria decipiens ssp. camptotricha 'Bird's Nest Cactus'

Mammillaria decipiens ssp. camptotricha 'Bird's Nest Cactus' Highlights:  Mammillaria 'Bird's Nest Cactus' is a green cactus with cylindrical tubercles that grow long white and brown spines that can grow over 1" long. This Mammillaria grows in a clumping fashion. Produces small yellow flowers.  Easily propagated from offsets. Hardy to Zone 10 (30°-35° F). Mammillaria will not survive a hard frost. However, cactus can easily be grown indoors under grow lights or in a sunny window if there is a risk of temperatures dropping below 35° F. If there is only a risk of freezing temperatures for a few days, most succulents do just fine outside if they are covered by frost cloth or a sheet until temperatures increase (I'm talking to you, Zone 9 friends). Mammillaria Care: As with all cactus, it is best to follow a "soak and dry" schedule where you water your plants deeply (until water runs out the bottom drain holes), and then allow your soil to dry completely before watering again.
