Astrophytum myriostigma nudum

Astrophytum myriostigma nudum

Origin of Name

“Astrophytum myriostigma nudum” is a distinctive variety within the Astrophytum genus. The genus name “Astrophytum” is derived from the Greek words “astron,” meaning star, and “phyton,” meaning plant, referring to the star-like shape of the cacti in this genus. The species name “myriostigma” translates to “countless spots,” alluding to the white, flecked areoles that typically dot the green surface of the plant. The term “nudum” indicates this variety’s lack of the white, woolly flecks that are characteristic of the standard Astrophytum myriostigma, presenting a more “naked” or clean appearance.

Technical Description of Plant

“Astrophytum myriostigma nudum” is notable for its smooth, spherical to columnar body, which can grow up to 3 feet tall. Unlike the typical Astrophytum myriostigma, the ‘nudum’ variety has a clear, unmarked green skin, giving it a sleek and minimalist aesthetic. This plant typically has five ribs, though it can vary, forming a star-shaped cross-section that becomes more pronounced as the plant matures. The absence of the white dots offers a unique opportunity to appreciate the deep green hue of the cactus. It blooms with large, yellow flowers from the crown of the plant during the summer, providing a striking contrast to its green body.

Origin of Plant

Astrophytum myriostigma, including its nudum variety, is native to the highlands of northeastern and central Mexico. Adapted to arid environments, it has evolved to store water within its thick, ribbed body, enabling it to withstand prolonged periods of drought. The ‘nudum’ variety has been selectively bred by enthusiasts for its distinct appearance, emphasizing the beauty of its unadorned, green skin.

Conservation Status

While “Astrophytum myriostigma” as a species is not currently listed as endangered, it, like many native cacti, faces threats from habitat loss, overcollection, and climate change. Conservation efforts focus on habitat preservation and the promotion of responsible collection and propagation practices. The ‘nudum’ variety, being primarily cultivated, does not directly impact wild populations but highlights the importance of plant diversity and conservation.

Care Instructions

“Astrophytum myriostigma nudum” requires bright, indirect light or partial shade to thrive. It prefers well-draining soil specifically formulated for cacti and succulents. Water moderately during the active growing season, allowing the soil to dry thoroughly between waterings, and reduce watering in the winter to prevent root rot. This plant is not frost-tolerant and should be protected from cold temperatures. Fertilize sparingly with a low-nitrogen, balanced fertilizer during the growing season to support health and flowering. Due to its slow growth rate, repotting is only necessary every few years to refresh the soil or accommodate growth.
