栖息环境

山坡、林缘、路边和灌丛,耐瘠薄;广泛作观赏和水土保持植物,在美国东南部成为入侵种。中国农村曾用来喂猪。

分布

原产东亚,从西伯利亚东南部到中国东部、蒙古、朝鲜半岛和日本;中国东北到华中、华南的山区常见,日本全境常见,是「秋七草」之首的「萩」。新加坡无。

花期

7 到 9 月开花,日本的「萩」是初秋的象征,寺院的萩花小径在 9 月中旬最盛。

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。

细碎的紫红小花要拍成片的气势,用长焦压缩拱垂的枝条,背景选暗;单朵蝶形花微距。京都寺院的萩花与石灯笼、小径是经典组合,雨后花瓣落在石阶上也好。

适合的摄影风格

Identification

An erect shrub 1–3 m tall and as wide, smaller in cold climates, growing from the ground to 1.5 m in one season; a thick root system and stems up to 3 cm across. Leaves of three oval leaflets up to 5 cm. Racemes of up to 15 open pea flowers in pink and purple, plus cleistogamous flowers that never open. A flat pod nearly 1 cm long with one seed. Very variable, with many cultivars. The epithet means two-coloured.

Habitat

Hillsides, forest edge, roadsides and scrub, tolerant of poor soil; widely planted for ornament and erosion control and invasive in the south-eastern United States. Once used as pig fodder in rural China.

Distribution

Native to eastern Asia from south-eastern Siberia to eastern China, Mongolia, Korea and Japan; common in the hills from north-east to central and southern China and throughout Japan, where as hagi it heads the seven autumn herbs. Absent from Singapore.

Season and behaviour

Flowers from July to September; hagi is the emblem of early autumn in Japan, and temple hagi paths peak in mid-September.

Photography tips

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

The small purple-red flowers want the mass of a whole shrub: compress the arching branches with a long lens against a dark background, with macro for a single pea flower. Hagi with stone lanterns and paths in Kyoto temples is the classic, and petals fallen on wet stone steps after rain work too.

Photographic styles

Purple-red on arching early-autumn branches; hagi in a Japanese temple.
