Origin of Name: The name Astrophytum myriostigma Quadricostatum derives from its unique characteristics and classification within the cactus family. The genus name Astrophytum translates to “star plant,” which refers to the star-shaped appearance of certain species. The species name myriostigma means “many spots,” highlighting the distinctive markings found on the plant's surface. The variety Quadricostatum refers to the four prominent ribs on the cactus.
Origin of the Plant: Astrophytum myriostigma is indigenous to the arid regions of northeastern Mexico, particularly in the states of San Luis Potosí and Nuevo León. It thrives in dry, rocky soil and can often be found in crevices where it receives ample sunlight and minimal water. Over time, this species has become popular among collectors and enthusiasts due to its unique visual appeal and fascinating growth habits.
Technical Description: This stunning cactus can reach up to 12 inches in height, with a cylindrical or short-columnar form. The Quadricostatum variety is characterized by its four distinct ribs, which are often adorned with a waxy coating giving it a unique sheen. In spring, the plant produces large, yellow flowers that emerge from the apex of the cactus, adding a vibrant contrast to its green body. The flowers have a star-like shape, making them an exquisite sight during blooming season.
Conservation Status: While Astrophytum myriostigma is not currently classified as endangered, its natural habitat is threatened by urbanization, agriculture, and over-collection for the ornamental trade. As a result, it is essential to source this plant from reputable growers who cultivate it sustainably. Conservation efforts are vital to ensure that this unique species continues to thrive in the wild.
Care Instructions: To successfully cultivate Astrophytum myriostigma Quadricostatum , follow these care guidelines:
- Light: Provide bright, indirect light, or direct sunlight for several hours a day to encourage healthy growth.
- Water: Water sparingly during the growing season (spring and summer), allowing the soil to dry out completely between waterings. Reduce watering during the dormant season (fall and winter).
- Soil: Use a well-draining cactus mix to prevent root rot. A mix of potting soil, sand, and grit works well.
- Temperature: Prefer warm temperatures ranging from 70°F to 90°F (21°C to 32°C) in the growing season. Protect from frost, as this species is sensitive to cold temperatures.
- Fertilization: Fertilize with a diluted cactus fertilizer during the growing season to promote healthy growth and blooming.
