识别特征

食虫植物,叶卷成矮胖、横卧的瓶子,绿色带紫红的脉纹、日晒后整体转紫(种加词即「紫色」),瓶口的盖直立、不遮雨,所以瓶里积满雨水,昆虫落水淹死后被细菌和瓶内的小生物群分解。花单生于高花葶上,下垂,紫红色,五枚花瓣垂在一个伞状的大花柱盘周围,像一把倒置的小伞。是瓶子草属分布最广、最常见的种,也是唯一能生活在冷温带的种;加拿大纽芬兰与拉布拉多省省花。

栖息环境

贫瘠酸性的泥炭沼泽,喜全日照和湿润;世界各地作盆栽,在欧洲归化。

分布

原产北美洲东部海岸、五大湖区、几乎整个加拿大,以及华盛顿州和阿拉斯加;东亚全部是栽培:日本的食虫植物爱好者和园艺店常见(日文名「ムラサキヘイシソウ」),中国和新加坡的花市偶见。

花期

花 5 到 6 月;瓶子春季新生、夏末颜色最深,秋冬宿存。

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。

横卧的瓶子要趴下来平视,微距拍瓶身的紫红脉纹和瓶口的毛;逆光下瓶身半透明、能看到水位。俯拍瓶口积水里的倒影和落虫。花在瓶子上方,伞状的花柱盘要从下往上拍。栽培株为主,别采集。

适合的摄影风格

逆光半透明的紫瓶;倒置小伞般的花。

相似物种

黄瓶子草等直立的瓶子草(瓶高而直、盖遮口);猪笼草(笼生于叶尖、藤本);眼镜蛇草(瓶顶弯如蛇头)。

Identification

A carnivorous plant whose leaves roll into squat sprawling pitchers, green with purple-red veins and turning purple overall in sun (the epithet), the lid upright and not covering the mouth, so the pitcher fills with rain in which insects drown and are broken down by bacteria and the pitcher's small community. Solitary nodding purple-red flowers on tall scapes, five petals hanging round a large umbrella-like style disc, like an upturned parasol. The most widespread and common Sarracenia and the only one of cold temperate climates; the provincial flower of Newfoundland and Labrador.

Habitat

Poor acid peat bogs in full sun and moisture; a pot plant worldwide, naturalised in Europe.

Distribution

Native to the eastern seaboard of North America, the Great Lakes, nearly all of Canada, and Washington State and Alaska; entirely cultivated in East Asia, common among Japanese carnivorous-plant growers and in garden centres (murasaki-heishisō), occasional in Chinese and Singaporean flower markets.

Season and behaviour

Flowers in May and June; pitchers grow in spring, colour deepest by late summer and persist through winter.

Photography tips

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

Sprawling pitchers mean lying down at their level, with a macro for the purple-red veins and the hairs at the mouth; against the light the pitcher is translucent and shows the water level. From above for reflections and drowned insects in the mouth. The flower stands above the pitchers and its parasol style disc wants a view from below. Cultivated plants; never collect.

Photographic styles

A translucent purple pitcher against the light; a flower like an upturned parasol.

Similar species

Upright pitcher plants such as Sarracenia flava (tall straight pitchers, lid over the mouth); Nepenthes (pitchers from leaf tips, climbers); cobra lily (hooded like a snake's head).
