识别特征

多年生草本,丛生,多数高约 1 米,温带常作一年生。茎粗壮、四棱、分枝多、在节上生根,常半匍匐。花漏斗状,傍晚到黄昏(四到八点)开放,所以英文叫「四点钟花」;同一株上同时有不同颜色的花,单朵也可以有扇形、条纹或斑点状的杂色,纯色有黄、红、洋红、粉或白。果实球形、有皱纹、成熟时黑色,像小地雷,故名「地雷花」。

栖息环境

庭院、路边、墙根和荒地,极易自播,是中国乡镇最常见的庭院花之一;据信阿兹特克人就已栽培。

分布

原产美洲热带,Jalapa 是墨西哥韦拉克鲁斯州首府的名字;现遍布世界温暖地区。中国各地、日本和新加坡都常见栽培和逸生。

花期

6 到 10 月,每天傍晚开放、次日上午闭合,雨天和阴天也会白天开。拍它要在黄昏或清晨。

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。

它在黄昏开放,正好是蓝调时刻:用小光源补一点暖光,或用三脚架在暮色里长曝光。同一株上多色和杂色花是题材本身,微距正面拍杂色的花瓣。清晨尚未闭合的花带着露水也好。

适合的摄影风格

黄昏开放的杂色花;暮色里的庭院。

Identification

A bushy perennial herb mostly about 1 m tall, grown as an annual in temperate zones. Thick, four-angled, much-branched stems rooting at the nodes and often sprawling. Funnel-shaped flowers open from late afternoon to dusk, between four and eight o'clock, hence the English name; flowers of different colours grow on one plant and a single flower can be splashed with sectors, flakes and spots, the plain colours yellow, red, magenta, pink or white. The spherical wrinkled fruit turns black when ripe, like a little land mine, the source of its Chinese nickname.

Habitat

Gardens, roadsides, wall bases and waste ground, self-seeding freely; one of the commonest dooryard flowers of Chinese towns and villages, and believed to have been grown by the Aztecs.

Distribution

Native to tropical America, Jalapa being the capital of Veracruz in Mexico; now throughout the warm world. Commonly grown and escaped across China, in Japan and in Singapore.

Season and behaviour

June to October, opening each evening and closing the next morning, also open by day in rain and cloud. Photograph it at dusk or dawn.

Photography tips

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

It opens at dusk, right in the blue hour: add a touch of warm light from a small source, or use a tripod for a long exposure in the twilight. The many colours and splashed flowers on one plant are the subject, with head-on macro for the variegated petals. Dewy flowers still open at dawn work too.

Photographic styles

Splashed flowers opening at dusk; a yard in twilight.
