Pentagram maple
Distribution of origin: produced in Northeast China, North China to the Yangtze River Basin; North Korea, Japan also has distribution. In many places in North China, the name "five-pointed maple" is often a yuanbao maple, and attention should be paid to the difference. Growth habits: temperate tree species, weak light-loving, slightly shade-tolerant, prefer cool and humid climate, the soil requirements are not strict, can grow on neutral, acidic and calcareous soils, but the soil layer is deep, fertile and moist to grow best, and grow poorly on clay soil. The growth rate is medium, deep rooted and wind resistant
Morphological characteristics: deciduous tree, up to 20 m, palm-shaped 5 lobes, lobes are wide, the apex tail is sharply pointed, the lobes are no longer divided into 3 lobes, the base of the leaf is often heart-shaped, the bottom 2 lobes do not unfold downwards, but sometimes 2 small lobes can be split again to form 7 lobes. The wings are longer, 1.5 to 2 times larger than the core.

Red maple
Red maple trees are 2-4 meters tall, and the branches are slender and smooth, with a purple-red color. The leaves are palmate, 5-7 deeply lobed, 5-10 cm in diameter, lobed ovate lanceolate, apex-tailed tip, with heavy serrations at the margins. The top of the flower is inflorescence, purple.

Red maple (acer palma tum); alias purple red chicken claw maple; maple genus of maple family is mainly distributed in subtropical China, especially in the Yangtze River Basin, and is cultivated in most parts of the country. Spring is more lush, winter withering. With tree species. Sexually prefer humid, warm climate and cool environment, more shade-tolerant, hardy, avoid hot sun exposure, but spring and autumn can also grow in full light. Soil requirements are not strict, suitable for growing in fertile, humus-rich acidic or neutral sandy loam soils, not tolerant of waterlogging; The tree is open and the twigs are slender. The bark is smooth and grayish brown. The single leaves alternately, often at the top of the branches. The leaves are palmately deeply lobed, lobes 5-9. The lobes are deep to the base of the leaf, the lobes are long ovate or lanceolate, and the leaf margins are sharply serrated. The leaves are red in spring and autumn, and purple in summer.

Feather maple
Feather maple, also known as fine-leaved chicken claw maple, feather maple, tower maple. It is a maple maple in the family Maple family, Maple maple (a. palmatum) of the horticultural variant. The feather maple is a deciduous shrub and generally does not exceed 4 meters in height. New branches are purple-red, mature branches are dark red. In early spring, the young leaves are bright red, dense white soft hairs, the leaves gradually fall off after stretching, and the leaf color also changes from bright to lilac or even dark green; the origin is distributed from Henan to the Yangtze River Basin. The canopy is unfolded, the leaves are finely lobed, the autumn leaves are dark yellow to orange-red, and the branches are slightly droopy. Neutral, prefers warm climates and is not hardy.
Biological and ornamental characteristics: canopy unfolding, fine rows of branches and leaves, autumn leaves dark yellow to orange-red, slightly droopy branches.
Feather maple likes warm and humid, cool climate environment, like light but afraid of the sun, belongs to the neutral shade tree species, summer in the dry hot wind will cause leaf edge dry curls, high temperature sunburn will also damage the bark, feather maple although like warm, but is still relatively hardy, in the Yellow River Basin area, winter temperature as low as -20 °C, but as long as the environment is good, can still be exposed to winter. As for the north of the Yellow River, it is advisable to plant potted plants, and it is advisable to enter the house in winter. Feather maple can adapt in the range of soil ph5.5 to 7.5, so it can grow in slightly acidic soils, neutral soils and calcareous soils
