Mammillaria Plumosa, also called Feather Cactus, is a rare collector cactus native to the rocky limestone hillsides of northeastern Mexico. It is a member of the Cactaceae family and grows as a clustering, drought-tolerant succulent that requires minimal care.
Dense, soft white feathery spines cover each tubercle, creating a fluffy, cloud-like appearance across the entire plant. Mammillaria Plumosa grows in a clumping habit, slowly spreading outward into a wide, cushion-like mound of individual heads that resembles a living snowball. The overall texture is almost impossible to mistake for any other small cactus.
Small pale pink to white flowers emerge in a ring around the crown of each head, typically blooming from late autumn through early winter. A drop in night temperature triggers flowering, so move it to a cooler spot during autumn evenings to encourage blooms. The flowers stand out against the dense white fuzz of the spines.
Mammillaria Plumosa releases oxygen at night and can survive up to ten days without water. Move it outside for summer on a patio or balcony, but keep it covered from rain since excess moisture causes rot. It is pet-friendly, though the sap can cause mild skin or paw irritation, so place it on a high shelf out of reach. It tolerates dry heated air and grows well under bright office LED lights when rotated regularly.
