Family: It belongs to the Convolvulaceae family. This family is characterized by its funnel-shaped flowers and often includes climbing or twining plants. Other well-known members of this family include morning glories and sweet potatoes.
Common Names: Skyblue Clustervine and Pentantha are the most widely used common names in English.
Description: The description provides a detailed look at the plant's physical attributes, including its herbaceous, pubescent stems, its ovate leaves with cordate bases, its dense flower cymes, and its globose, brown fruit capsules.
Habit: The term "climber" or "vine" describes its growth habit, as it uses its stems to climb and twine around other plants or structures.
Availability
Jacquemontia pentantha is native to tropical and subtropical regions of the Americas, but it has been introduced and naturalized in many other parts of the world. Its availability is therefore dependent on its natural range and where it has been cultivated.
Geographical Range: It is found in the southern United States (particularly Florida), Mexico, Central America, the Caribbean, and parts of South America. It has also been introduced to and can be found in various parts of Asia and Africa where the climate is suitable.
Habitat: It typically grows in disturbed areas, along roadsides, in fields, and in open woodlands. It is a resilient plant that can tolerate a variety of soil types, but it thrives in full sun and well-drained soil.
Commercial Availability: While not a staple in the commercial herb market, it may be available from specialty nurseries that focus on native or rare plants. Its seeds or cuttings can also be found online from various plant enthusiasts and suppliers. Its use is more prevalent in traditional and local contexts rather than in a large-scale commercial setting.
External Look
The external appearance of Jacquemontia pentantha is one of its most defining features and a key to its identification.
Stems: The stems are herbaceous (non-woody) and can be pubescent (covered in fine hairs) to glabrate (becoming hairless with age). They twine and climb, allowing the plant to reach heights of several meters.
Leaves: The leaves are a dark green color and are ovate to broadly ovate in shape. They measure 3-6 cm in length and are attached to the stem by a petiole. A key characteristic is their cordate (heart-shaped) base and acuminate (tapering to a point) apex. They are typically glabrate (smooth) on the surface.
Flowers: The flowers are the star of the show. They are a striking sky-blue color, though they can sometimes be white. They are funnel-shaped, similar to other morning glories, and are about 2 cm long. The flowers are arranged in dense cymes, or clusters, often with only one or two flowers open at a time, which gives the plant a continuous display of color.
Sepals: The sepals, which are the small, leaf-like structures at the base of the flower, are ovate to lanceolate in shape and are pubescent (hairy). They are typically 4-5 mm long.
Fruit and Seeds: The fruit is a small, globose (spherical), brown, glabrous (hairless) capsule. When mature, it splits open to release the seeds. The seeds are brown, about 2.5 mm long, and are also glabrous.
