原产美洲,从美国南部经墨西哥、中美洲到南美北部;新加坡的路边和组屋区常见,华南(广东、海南、云南)和台湾栽培,日本冲绳和温室有栽培。

花期

热带全年断续开花,春夏最盛;新加坡雨季后一树金黄。

拍摄建议

以下为 FilmAnalysis 编辑的拍摄经验,不是资料来源中的内容。

金黄的喇叭在直射光下容易过曝,减一档,或者等阴天和傍晚;逆光下花冠半透明,喉部的红脉显出来。整树盛花用长焦压缩成黄块,单簇用微距拍喉部。细长的蒴果在花后挂满枝头,是另一个题材。

适合的摄影风格

金黄喇叭的簇;逆光下的半透明花冠。

相似物种

黄钟花属其他种;黄花风铃木(Handroanthus chrysotrichus,落叶后开花,叶掌状复叶);软枝黄蝉(花黄,叶轮生,藤本)。

Identification

A semi-evergreen shrub or small tree to 10 m. Opposite odd-pinnate leaves with three to thirteen serrate leaflets 8–10 cm long, glabrous, lanceolate and long-acuminate. Large showy golden yellow trumpets in clusters at the branch tips, the corolla bell- to funnel-shaped, five-lobed and weakly two-lipped, often red-veined in the throat, 3.5–8.5 cm long. Narrow capsules up to 25 cm long hold many yellow seeds with membranous wings, spread by wind. The official flower of the US Virgin Islands and the floral emblem of the Bahamas.

Habitat

Roadsides, parks and gardens of tropical cities, drought-tolerant and sun-loving; a weed in some regions.

Distribution

Native to the Americas from the southern United States through Mexico and Central America to northern South America; common on Singapore's roadsides and housing estates, grown in southern China (Guangdong, Hainan, Yunnan) and Taiwan, and in Okinawa and glasshouses in Japan.

Season and behaviour

On and off all year in the tropics, most in spring and summer; a tree of gold after the rains in Singapore.

Photography tips

These are the FilmAnalysis editors' notes, not content from the sources.

Golden trumpets blow out in direct sun, so a stop under, or wait for cloud and evening; against the light the corolla turns translucent and the red throat veins show. A tree in full flower compresses to a yellow block with a long lens; a single cluster in macro for the throat. The long capsules hanging after flowering are another subject.

Photographic styles

Clusters of golden trumpets; translucent corollas against the light.
