Tell me about the fallen tiger.

Parthencissus Cephalotaxus is also known as Lycopodium fasciculatum, Pterocarya, Crocodile, Red Silk Grass, Pueraria lobata, Pashanhu, Red Grapevine, Bashan Tiger and Grape Family.

Plant morphology:

1, a large deciduous woody vine similar in shape to wild vines. Rattan stems can be as long as 18 meters (about 60 feet). Flowering in summer, small flowers, inconspicuous clustering, yellow-green or berry purple-black, opposite to leaves. Flowers are mostly hermaphroditic, and cymes are often planted on short branches between two leaves, which are 4~8cm long and shorter than petioles. Spend 5 numbers; Calyx entire; Petal apex reflexed, ovary 2-loculed, with 2 ovules per locule.

2. The bark has lenticels and the pith is white. The branches are stout, the old branches are grayish brown, and the young branches are purplish red. There are tendrils on the branches, which are short and multi-branched. There are sticky suckers at the top and tip of tendrils, which can be attached to objects, whether rocks, walls or trees.

3. Leaves alternate, lobular hypertrophy, wedge-shaped base, large variation, coarse serrated edge and symmetrical veins. The leaves on the flower branches are ovate in width, 8~ 18cm long and 6~ 16cm wide, and often 3-lobed, or the leaves on the lower branches are divided into 3 leaflets with a heart-shaped base. The leaves are green and hairless, with white powder on the back and hairy veins on the back, which turn bright red in autumn. The leaves on the young branches are very small and often do not divide. Berries are small spherical and blue-black when mature, which is popular with white powder and birds. Flowering in June and fruiting in September to 65438+ 10.

Growth habit

Parthenocissus tricuspidata has strong adaptability and likes humid environment, but it is not afraid of strong light, cold-resistant, drought-resistant, barren-resistant and has wide climate adaptability. It can also remain semi-evergreen or evergreen in winter south of the warm temperate zone. Resistant to pruning, afraid of water accumulation, lax in soil requirements, can thrive in wet or sunny places, but grows best in wet and fertile soil. It has strong resistance to harmful gases such as sulfur dioxide.

geographical distribution

Climb on rocks, trees, walls and mountains. Originated in eastern Asia, Himalayas and North America, introduced to other regions, and also distributed in South Korea and Japan. Distributed in Henan, Liaoning, Hebei, Shaanxi, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan, Hubei, Guangxi, Guangdong, Sichuan, Guizhou, Yunnan and Fujian.

In summer, there are dense branches and leaves, which often cling to walls or rocks, and are suitable for planting in fences, fences, garden entrances, bridges and stone ridges. It can be used to green house walls and park rocks, which can not only beautify the environment, but also cool down, adjust the air and reduce noise.
