Overview

Prestonia quinquangularis is a plant with a climbing habit in the genus Prestonia, part of the Apocynaceae family, with deciduous foliage. Prestonia quinquangularis grows best in full sun, and tolerates loam soils and neutral pH. Its UK hardiness is rated H4. Suggested uses include ornamental. It is native to Parque Nacional Natural Tinigua, Amazonas, Antioquia, Arauca, Atlántico, Bolívar, Córdoba, Cundinamarca, La Guajira, Guaviare, Meta, Quindío, Risaralda, Santander, Tolima and Valle.

About

Prestonia quinquangularis is a climbing, deciduous member of the Apocynaceae native to multiple regions of Colombia, including Amazonas and Antioquia. It establishes on south-facing, sheltered sites and benefits from full sun and consistently moist, neutral loam. In the UK it carries an H4 hardiness rating (average) and is grown principally for ornamental value. Flowering occurs from July to September.

In the garden

Prestonia quinquangularis is a climbing Apocynaceae from several Colombian departments and protected areas, where it occurs across a range of lowland and montane provinces. In cultivation it is treated as a south-facing climber that prefers a sheltered position and plenty of direct light; those conditions reflect its natural distribution. Plant it into a neutral, loamy soil kept reliably moist rather than allowed to dry out; exposure to wind should be minimised to protect shoots and flowering. The species is rated H4 — average hardiness in UK terms — so give it the warmest available wall or sheltered border you can provide to reduce winter stress. Maintain moisture through summer to support flowering and to reduce transplant shock. Use Prestonia quinquangularis as an ornamental climber on south-facing walls, pergolas or within a conservatory extension where full sun and shelter can be provided. It is particularly appropriate where a summer display is wanted, since blooms appear between July and September.
