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.
