Overview

Eccremocarpus scaber is a perennial climber in the genus Eccremocarpus, part of the Bignoniaceae family. Eccremocarpus scaber grows best in full sun and partial shade, and tolerates well-drained and fertile soils and neutral and slightly acidic pH. Its UK hardiness is rated H3. Suggested uses include climbing trellis, pergola and wall cover. It is native to Chile, Argentina and Peru.

About

Eccremocarpus scaber is a perennial climber in the Bignoniaceae that provides an extended flowering period from July to October. Native to Chile, Argentina and Peru, it is suited to training on vertical supports. Plant in well‑drained, fertile soil that is neutral to slightly acidic and keep soil moisture moderate. In the UK it suits a south‑facing, sheltered to semi‑exposed position and carries an H3 (borderline) hardiness rating.

In the garden

Eccremocarpus scaber is a perennial climbing species in the Bignoniaceae, originating from Chile, Argentina and Peru. Gardeners value it for its long flowering season, which runs from July to October, and for its suitability to be trained over structures where seasonal bloom is wanted. Position it where it receives full sun or partial shade and where soil drains freely; a fertile, neutral to slightly acidic soil with moderate moisture suits it best. Give a south‑facing aspect in the northern hemisphere and avoid the coldest, exposed corners of a garden: its UK hardiness is H3 (borderline), so it benefits from a sheltered spot or microclimate where winter exposure is reduced. Use Eccremocarpus scaber on a trellis, pergola or to cover a wall where seasonal flowering is required rather than dense year‑round screening. Its flowering window from July to October makes it particularly useful for extending floral interest into late summer and early autumn on south‑facing structures in milder UK locations.
