Mammillaria plumosa aka Feather Cactus

Taxonomy

Mammillaria plumosa, also known as the feather cactus, is a species of flowering plant in the family Cactaceae, native to Northeastern Mexico. This clumping cactus forms low dense mounds covered with white feathery spines, which not only add interest but also provide shade from heat and sun. The spherical stems, measuring 7 cm in diameter, are completely covered in white downy spines. It grows to a height of 12 cm and a width of 40 cm. In late summer, it produces yellowish-white flowers, measuring 1.5 cm in length. Despite its soft and fluffy appearance, the "feathers" hide sharp spines. The plant's status is listed as "Near Threatened" by the IUCN Red List. This cactus thrives in container gardens and typically blooms in the spring, although it can flower throughout the year in certain areas.

How to care for Feather Cactus

Difficulty

Caring for Feather Cactus is a breeze, as it is highly adaptable and forgiving to minor neglect.

Water

Feather Cactus does best in dry soil and should only be watered sparingly.

Soil

When growing the Feather Cactus, it's important to use a potting soil that is well-draining and does not retain excessive moisture. An optimal soil mix should contain a high proportion of perlite or vermiculite for good drainage and some organic matter for nourishment. Simply add a few scoops of perlite to regular cactus soil to achieve this.

Lighting

Feather Cactus requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Feather Cactus is always in the right place to thrive.

Dormancy

During the cold period, it is common for Feather Cactus to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.

Humidity

Feather Cactus plants thrive in dry environments, however, if you choose to provide extra humidity or mist your plant, the lingering water on the leaves can create an ideal environment for certain types of harmful fungi.

Fertilizer

The Feather Cactus grows at a slow pace and doesn't require any supplementary fertilizers. By renewing its potting soil once a year, it should receive enough nourishment. Remember, plants obtain their energy from sunlight, not fertilizers.

Region of origin

Feather Cactus’s native range is the Southwestern United States, Central America, and the Caribbean.
