Product Details


Feather Cactus (Mammillaria plumosa) (F.A.C. Weber): A cuddly cactus that has traded in its spines for piles of fluff! Its "spines" are so feathery that it looks more like a baby bird than a cactus. This species from Northeastern Mexico can grow to about 5.0" tall and 16.0" wide as mounded clusters of small, round offsets. Tiny, bell-shaped flowers tend to appear in late summer and have a sweet fragrance. After trials by the Royal Horticultural Society, M. plumosa earned the Award of Garden Merit for its appearance and vigor. This plant is fully rooted in a 3.5" round, plastic pot.

Please note: The fluffy covering makes this species particularly susceptible to rot; water very sparingly and avoid getting the feathery spines wet.

This variety of cactus will not survive a frost, but if there is a risk of freezing temperatures it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again.
