Origin of Name

The genus name "Pachypodium" comes from the Greek words "pachys," meaning thick, and "podion," meaning foot, referring to the thick, swollen base or trunk characteristic of these plants. "Lamerei" honors the French botanist Léon Lamer, who is credited with its discovery. The term "inermis" means spineless, highlighting the lack of spines on this cultivar, and "crest" refers to the crested, or cristate, growth form where the stem grows in a wavy, fan-like pattern rather than the usual cylindrical shape.

Technical Description of Plant

Pachypodium lamerei 'Inermis Crest' exhibits a remarkable crested growth pattern, where the stem broadens and undulates horizontally, creating a sculptural, wavy effect. Unlike the standard Pachypodium lamerei, which features sharp spines along its grey-green stem, the 'Inermis' variety is notably spineless, offering a smoother appearance. This crested form can vary significantly in size and shape but generally remains compact, making it suitable for container cultivation. The plant occasionally produces small, yellow flowers at the tips of the crests, though flowering is less common in crested specimens.

Origin of Plant

Pachypodium lamerei is native to southern Madagascar, where it grows in arid, rocky environments. The 'Inermis Crest' cultivar, however, has been developed through selective breeding and cultivation, emphasizing its unique spineless and crested characteristics. It is a product of horticultural expertise rather than a naturally occurring variety.

Conservation Status

As a cultivated variety, Pachypodium lamerei 'Inermis Crest' does not have a specific conservation status. However, many Pachypodium species are at risk in their natural habitats due to land conversion and over-collection. Cultivating and trading cultivated varieties like 'Inermis Crest' can help reduce pressure on wild populations.

Care Instructions

Pachypodium lamerei 'Inermis Crest' requires bright, indirect light and well-draining soil. Water moderately during the growing season but allow the soil to dry out completely between waterings. In winter, reduce watering significantly to prevent root rot. This plant prefers warm temperatures and should be protected from frost. Fertilize lightly with a balanced, water-soluble fertilizer during the growing season to support growth.

With its unique appearance and manageable care requirements, Pachypodium lamerei 'Inermis Crest' is an exceptional choice for those looking to add a sculptural element to their succulent collection or indoor garden. Its rare crested form ensures it remains a focal point in any setting, captivating all who see it.
