Matelea cyclophylla

Origin

Matelea cyclophylla is native to Mexico, specifically occurring in the western and southern regions of the country. It is most commonly found in the states of Guerrero, Morelos, and Oaxaca. It belongs to the Apocynaceae family (formerly Asclepiadaceae), often referred to as the "Milkweed" family.

Habitat

In its natural environment, this species thrives in tropical deciduous forests and thorn scrublands at elevations between 500 and 1,500 meters. It typically grows in rocky, well-drained limestone soils, often nestled at the base of trees or shrubs that provide climbing support for its vines and dappled shade for its sensitive caudex. The habitat is characterized by a distinct "wet-and-dry" cycle: it remains dormant during the hot, dry season and grows rapidly during the summer rains.

Description

Matelea cyclophylla is a spectacular caudiciform plant prized for the dramatic contrast between its rugged, prehistoric-looking base and its delicate tropical foliage.

• Caudex: The most sought-after feature is its large, perennial woody caudex. As the plant matures, the surface develops thick, corky, polygonal fissures (resembling a tortoise shell), which serve as a protective layer against heat and water loss.

• Vines & Foliage: During the growing season, it produces slender, twining vines that can grow several meters long. The leaves are large, bright green, and heart-shaped (cordate), appearing in pairs along the stems.

• Flowers: It produces clusters of star-shaped, five-petaled flowers. The blooms are a deep, dark maroon to chocolate-purple color with a velvety texture. They emit a faint, musky odor to attract specific pollinators like flies.

• Cultivation: It is a summer grower. It requires a very porous mineral substrate and prefers bright, indirect light. Unlike some desert succulents, it enjoys regular watering during the peak of summer but must be kept completely dry during its winter dormancy to prevent the caudex from rotting.

Nursery Tip: When displaying or potting, the caudex can be partially exposed for aesthetic appeal, but in its juvenile stage, keeping it slightly buried helps accelerate the growth and "corking" of the bark.

Handling Note: Like most members of the Milkweed family, the sap may contain alkaloids that are irritating to the skin.
