识别特征

大型多年生草本,从根状茎长出假茎,叶质地厚实,约 85 厘米长、18 厘米宽,有中央凹槽,叶丛可高 3 到 6 米。花序从地面单独抽出,花葶高 1 米多,顶端是火炬般的头状花序:蜡质的粉红(也有红和白)苞片层层叠叠像莲花或火炬,真正的花小、红色带白边,从苞片间依次露出。苞片是东南亚菜肴(叻沙、乌打)的香料,「姜花」「瓷玫瑰」由此而来。

栖息环境

热带雨林林缘和溪边湿润处,广泛种植于热带公园、度假村和庭院,是最醒目的热带观花植物之一。

分布

原产马来半岛、印尼群岛和新几内亚;新加坡的公园和植物园极常见,华南(广东、云南、海南)栽培,日本仅温室和冲绳。

花期

热带全年开花,雨季后最盛;一个花序可持续一个月,先紧实如火炬,后展开如莲花。

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。

蜡质的粉红苞片在柔光下像瓷,直射光下反光发白,减半档;侧光拍层叠的立体感,正面俯拍展开后的莲花状。真正的小红花要微距。花葶与巨大的叶丛分开生长,用长焦从低处拍花葶挺立于深绿前。

适合的摄影风格

瓷质的粉红火炬;俯拍展开的莲花状。

相似物种

红花月桃、艳山姜(花序下垂、白粉色);蜂巢姜(花序黄色蜂巢状);红姜花(Hedychium coccineum,花橙红、穗状)。

Identification

A large perennial whose pseudostems rise from a rhizome, with leathery leaves about 85 cm long and 18 cm wide with a central groove, the clump 3–6 m tall. The inflorescence comes up separately from the ground on a scape over a metre tall, topped by a torch-like head: waxy pink (also red and white) bracts layered like a lotus or torch, the true flowers small, red with white edges, emerging between the bracts in turn. The bracts flavour South-East Asian dishes (laksa, otak-otak), hence the names torch ginger and porcelain rose.

Habitat

Rainforest edge and damp streamsides, widely planted in tropical parks, resorts and gardens, one of the showiest tropical flowering plants.

Distribution

Native to the Malay Peninsula, the Indonesian islands and New Guinea; very common in Singapore's parks and botanic gardens, grown in southern China (Guangdong, Yunnan, Hainan), and in Japan only under glass and in Okinawa.

Season and behaviour

Flowers all year in the tropics, most after the rains; one head lasts a month, first tight as a torch, then opening like a lotus.

Photography tips

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

Waxy pink bracts look like porcelain in soft light and flare white in sun, half a stop under; side light for the layered relief, straight down for the opened lotus. The small true flowers want macro. The scape grows apart from the huge leaves, so a long lens from low down shows it standing before dark green.

Photographic styles

Porcelain-pink torches; the opened lotus from above.

Similar species

Shell ginger (drooping white-pink inflorescence); beehive ginger (yellow honeycomb heads); scarlet ginger lily, Hedychium coccineum (orange-red spikes).
