识别特征

常绿灌木或小乔木,通常高 6 米,野生可达 10 米。叶互生,革质,椭圆到卵形,2.6 到 6.3 厘米,边缘有细锯齿,深绿有光泽;嫩枝、叶柄和中脉有短柔毛。花单生,顶生或腋生,直径 5 到 7.6 厘米;野生型 6 到 7 枚白色花瓣,栽培品种有粉、红和复色,花瓣可超过 20 枚。与山茶的区别:花瓣一片片散落而不是整朵掉落,叶和花较小,秋冬开花。蒴果球形到梨形,密被绒毛。种子榨油,叶可制茶。

栖息环境

山地常绿林和林缘,广泛栽培于庭院、寺院和绿篱,在日本尤其普遍。

分布

原产日本南部(四国、九州)和琉球群岛,中国栽培(华东、华南庭院),日本全境栽培极普遍(日文名「山茶花」,冬天童谣里的花)。新加坡无。

花期

早花品种 9 到 10 月开始,晚花品种可到 4 月,主要 10 到 12 月;花期长,一片片落下的花瓣铺满地面。

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。

秋冬的低光正适合它,白花减半档,红花减一档;花瓣一片片落在苔藓或石阶上是它区别于山茶的画面,俯拍。叶和花都有光泽,侧光或偏振镜。冬天雪压着的茶梅加一档曝光。

适合的摄影风格

苔上散落的花瓣;冬日低光的花。

相似物种

山茶(叶和花更大,花整朵掉落,1 到 4 月开);油茶(花白,花期相近,叶更厚,油料作物);茶树(花小,白,秋季)。

Identification

An evergreen shrub or small tree usually 6 m tall, wild plants to 10 m. Alternate leathery leaves, elliptic to ovate, 2.6–6.3 cm, finely serrate, dark glossy green; young twigs, petioles and midribs shortly pubescent. Solitary terminal or axillary flowers 5–7.6 cm across; wild-type flowers with six or seven white petals, cultivars pink, red or bicoloured with over twenty petals. Told from Camellia japonica by petals that fall one by one rather than as a whole flower, smaller leaves and flowers, and autumn-winter flowering. Globose to pear-shaped densely tomentose capsules. The seeds give oil and the leaves tea.

Habitat

Montane evergreen forest and forest edge, widely planted in gardens, temples and hedges, especially commonly in Japan.

Distribution

Native to southern Japan (Shikoku, Kyushu) and the Ryukyus; cultivated in China (eastern and southern gardens) and extremely common in cultivation throughout Japan (sazanka, the flower of the winter nursery song). Absent from Singapore.

Season and behaviour

Early groups from September and October, late ones into April, mainly October to December; a long season, the petals carpeting the ground one by one.

Photography tips

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

The low light of autumn and winter suits it, half a stop under for white and a stop for red; petals scattered one by one on moss or stone steps are the picture that separates it from japonica, seen from above. Leaves and flowers are glossy, so side light or a polariser. Under snow, add a stop.

Photographic styles

Petals scattered on moss; flowers in low winter light.

Similar species

Camellia japonica (larger leaves and flowers, whole flowers dropping, January to April); oil-seed camellia (white, similar season, thicker leaves, an oil crop); tea plant (small white autumn flowers).
