  • Posted by Baja_Costero (Baja California - Zone 11b) on Feb 26, 2018 8:28 PM concerning plant:
    Low, furry, clumping Mammillaria from dry northeastern Mexico with white or pink flowers. A dry growing plant; provide excellent drainage and do not overwater. Avoid deep pots. Provide strong light; most pronounced plumage in full sun. Water the soil, not the plant, so that water does not accumulate under the feathery spines and cause complications. Easy to propagate by division, but you have to do it with care as there may be considerable tap roots, and broken stems are prone to rot. A great looking, fast growing, low-care plant for dry, exposed locations and a reliable (if sometimes a bit shy) bloomer. From Coahuila and Nuevo León.
