Origin of Name
The genus name "Mammillaria" comes from the Latin word 'mammilla', meaning nipple, referring to the nipple-like tubercles from which the plant's spines emerge. The species name "elongata" describes the elongated nature of the cactus' stems in its typical form. The term 'Crest' refers to the crested or cristate form of growth, where the cactus grows in a wavy, fan-like pattern instead of the usual round or elongated shape, caused by a mutation in the plant's growth point.
Technical Description of Plant
Mammillaria elongata 'Crest' features a broad, crested stem that grows horizontally, creating a wavy or fan-like appearance. The green, photosynthetic tissue is densely packed with small, white areoles from which emerge clusters of fine, golden-yellow spines. The crested form often results in a more compact plant, with the crest expanding in width rather than height. Like its non-crested counterpart, it may produce small, yellow or pink flowers that bloom in a ring around the upper part of the stem, adding to its decorative appeal.
Origin of Plant
Mammillaria elongata is native to central Mexico, where it grows in rocky outcrops and grasslands. The 'Crest' form is a mutation that can occur naturally but is most often propagated artificially for cultivation due to its unique appearance and desirability among collectors.
Conservation Status
The typical form of Mammillaria elongata is not currently listed as endangered. However, habitat destruction and overcollecting can pose threats to wild populations. The crested form, being primarily propagated for cultivation, does not face these threats directly but shares the general conservation concerns of its species.
Care Instructions
Mammillaria elongata 'Crest' thrives in well-draining soil and prefers a sunny to partly sunny location. While it can tolerate some direct sunlight, excessive exposure may cause scorching. Water moderately during the growing season, allowing the soil to dry out completely between waterings, and reduce watering in the winter. This plant is not frost-tolerant and should be protected from freezing temperatures. Fertilize lightly during the growing season with a cactus-specific fertilizer to promote growth and flowering.
