Origin of Name

The genus name "Frailea" is named after the Danish botanist Dr. Jens F. Fræile, who made significant contributions to the study of cacti. The species name "pumila" comes from Latin, meaning "dwarf," indicating the plant's small stature. The variety name "rubrispina" derives from the Latin words "rubris," meaning "red," and "spina," meaning "thorn" or "spine," referencing the distinctive red or reddish spines that characterize this variety.

Origin of Plant

Frailea pumila var. rubrispina is native to the arid regions of Argentina, particularly found in the provinces of La Rioja and Catamarca. This variety typically grows in rocky, well-draining soils in semi-desert environments, often in association with other desert plants where it can take advantage of limited moisture present in the ecosystem.

Description

Frailea pumila var. rubrispina is a small, globular cactus that usually reaches a height of 5 to 10 centimeters (2 to 4 inches) and can cluster to form small groups. It features a green body covered with prominent tubercles, which give it a textured appearance. The most striking feature of this variety is its short, stout spines, which are bright red, creating an eye-catching contrast against the green body of the cactus. The flowers are funnel-shaped and bloom in late spring to early summer, typically appearing in shades of yellow to cream and sometimes having faint reddish markings. The blooms emerge from the sides of the cactus and can enhance its aesthetic appeal.

Conservation Status

Currently, Frailea pumila var. rubrispina is not classified as endangered; however, it may face threats from habitat loss due to agricultural activities, climate change, and over-collection for ornamental purposes. Conservation efforts focused on protecting its natural habitat and promoting sustainable cultivation practices are vital for ensuring the survival of this unique variety.

Care

Caring for Frailea pumila var. rubrispina involves mimicking its native environment. Use a well-draining cactus mix that includes sand, perlite, or pumice to promote good drainage. Place the cactus in a location that receives bright, indirect sunlight. While it can tolerate some direct sunlight, be cautious of intense afternoon rays that could lead to sunburn. Water moderately during the growing season (spring and summer), allowing the soil to dry out completely between waterings. During the winter months, significantly reduce watering, as the cactus enters dormancy and requires less moisture. Fertilize sparingly using a diluted cactus fertilizer during the active growing season to encourage healthy growth and flowering. Regularly inspect for pests, such as mealybugs and aphids, to maintain the health and appearance of your Frailea pumila var. rubrispina, making it a charming addition to any cactus collection.
