Native to Madeira and the Canary Islands, this climbing or sprawling shrub has been cultivated widely in warm temperate and subtropical regions, particularly in Southern Europe and parts of Asia and South America. It bears bright yellow, tubular flowers that flare open at the tips into five narrow lobes, arranged in loose clusters that bloom mostly in spring and early summer. The flowers are strongly fragrant, with a scent that intensifies during the early morning and late afternoon, often compared to citrus with a slightly resinous undertone. The species has been recognized for its garden merit by horticultural societies in Europe for its consistent flowering under Mediterranean conditions. In traditional herbal practice in the Canary Islands, infusions made from dried flowers have been used as mild sedatives or respiratory aids, although these uses are not supported by controlled pharmacological studies. Some evidence suggests its essential oils contain low concentrations of benzyl acetate and linalool, compounds also found in aromatherapy oils. Photographed in Bogotá, Colombia.
