The Taiwan cherry ( Prunus campanulata ) is a species of the Prunus genus . It is spread from Taiwan and Japan via China to Vietnam.
description
Vegetative characteristics
Prunus campanulata grows as a small tree or shrub and reaches heights of 3 to 8 meters. The bark is blackish-brown. The bark of the branches is initially green and hairless, later grayish-brown to purple-brown. The winter buds are egg-shaped and bare.
The alternate leaves are divided into a petiole and a leaf blade. The bald petiole is 8 to 13 millimeters long and has two nectar glands in the upper area. The simple leaf blade is ovate, ovoid-elliptical to obovate-elliptical to obovate-elliptical with a length of 4 to 7 cm and a width of 2 to 3.5 cm and ends with a pointed tip. The leaf margin is more or less clearly serrated irregularly. There are eight to twelve lateral nerves on each side of the main nerve. The leaf blade glabrous or has tufts of trichomes on the branches of the nerves . The two stipules fall off.
Generative characteristics
The elliptical bud scales are about 5 millimeters long, about 3 millimeters wide and pressed on both surfaces, shaggy hairy. The inflorescence shaft is 2 to 3 millimeters long. Two to five flowers stand together in a dold-like inflorescence . The 1.5 to 2 mm large bracts are usually brown or rarely greenish-brown and have a glandular serrated edge. The bare or sparsely hairy flower stalk is 1 to 1.3 cm long and grows to a length of 1.5 to 2.5 cm when the fruit is ripe.
The hermaphroditic, radial symmetry , five-fold flowers have a diameter of 1.5 to 2 cm and open before the leaves unfold. The bald or very sparsely hairy flower cup (hypanthium) is bell-shaped, slightly swollen at its base, about 6 millimeters long and about 3 millimeters wide. The five sepals that can still be seen on the fruit are elongated, about 2.5 millimeters long and have a smooth edge. The five pink, free petals, which are darker at their base, are obovate and oblong. There are about 36 to 41 stamens present. The bald style is longer or rarely shorter than the stamens.
The red stone fruit when ripe is egg-shaped with about 10 × 5 to 6 millimeters. The endocarp or the stone core is shaped like a pit. The fruits ripen from April to May.
The flowering period extends from January to April.
The number of chromosomes is 2n = 16, less often 24.
Occurrence
The Taiwan cherry is native to Taiwan , Japan , Vietnam and the Chinese provinces of Fujian , Guangdong , Guangxi , Hainan , Hunan and Zhejiang .
The variety newly described in 2007 Cerasus campanulata var. Wuyiensis X.R.Wang, XGYi & CPXie is endemic in Wuyishan in Fujian Province, China. It thrives in evergreen forests at altitudes of around 900 meters. So far no name has been published within the genus Prunus and in the Flora of China the subgenera are published in the rank of genus.
use
The Taiwan cherry is rarely used as an ornamental plant in Central Europe (e.g. in Kurpark Badenweiler) because it is not very hardy. More common are the frost-hardy hybrids 'Okame' ( Prunus campanulata × Prunus incisa ), a graceful shrub, and 'Shosar' ( Prunus campanulata × Prunus sargentii ) with a columnar growth.
