识别特征

热带软茎常绿灌木,高 0.5 到 2.5 米,家庭栽培多不超过 30 厘米。总状花序直立,由层层叠叠鲜黄色的苞片组成,像一只金色的虾或一根棒棒糖,所以叫「金苞花」「黄虾花」「棒棒糖花」;真正的花白色,两侧对称、长喉、二唇形,从苞片间依次伸出,寿命短,而黄色的花穗能持续数周。种加词意为「黄色」。原生种另有苞片紫褐色的类型。低于 10 度需要保护。

栖息环境

热带花坛、绿篱和盆栽,喜半阴和湿润;东亚北部作温室和室内植物。

分布

原产秘鲁(一说还包括墨西哥和圭亚那);新加坡的公园和花坛常见,华南(广东、云南、台湾)栽培,日本仅温室和室内(日文名「ウコンサンゴバナ」)。

花期

热带全年开花,温暖的月份最盛;一穗黄苞片持续数周,白花每朵只开一两天。

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。

黄色的苞片穗是主体,白花从里面探出是点睛,微距侧面拍白花从黄苞片间伸出的瞬间;黄色在阳光下发白,减半档、阴天最好。竖幅拍成排的穗。深绿叶做背景,颜色干净。

适合的摄影风格

黄穗里探出的白花;成排的金色花穗。

相似物种

虾衣花(Justicia brandegeeana,苞片红褐、下垂如虾);珊瑚花(Justicia carnea,花粉红成头);黄虾花是本种别名。

Identification

A tropical soft-stemmed evergreen shrub 0.5–2.5 m, mostly under 30 cm in homes. Upright racemes of overlapping bright yellow bracts like a golden shrimp or a lollipop, hence golden shrimp plant and lollipop plant; the true flowers white, zygomorphic, long-throated and two-lipped, emerging one after another from the bracts and short-lived, while the yellow spike lasts weeks. The epithet means yellow. A purple-brown-bracted form also exists. Needs protection below 10 °C.

Habitat

Tropical beds, hedges and pots in half shade and moisture; a glasshouse and house plant in northern East Asia.

Distribution

Native to Peru (some sources add Mexico and the Guianas); common in Singapore's parks and beds, grown in southern China (Guangdong, Yunnan, Taiwan), glasshouse and indoor only in Japan (ukon-sangobana).

Season and behaviour

All year in the tropics, most in the warm months; a spike of yellow bracts lasts weeks, each white flower a day or two.

Photography tips

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

The yellow spike is the body and the white flower peeping out the point: a side macro at the moment a white flower emerges between the bracts; yellow bleaches in sun, so half a stop under, best under cloud. Rows of spikes in a portrait frame. Dark green leaves behind for clean colour.

Photographic styles

A white flower peeping from a yellow spike; rows of golden spikes.
