The annual flowering period is 3 times, with early spring flowering, early February flowering, mid-March to mid-April flowering, and the annual flowering period is 75 to 95 days. In this category, according to the different characteristics of leaves, it can be divided into four types: long Julia, round Julia, pointed Julia and thin Julia. In each type, 9 varieties are divided according to the color and petal morphological characteristics. Compared with the other two varieties, this variety has poor ornamental value of flowers and leaves, and has been gradually eliminated in production, but it has strong ecological adaptability, especially high temperature resistance, cold resistance and barren resistance, and can be used as the original material for variety breeding.

The second kind of Tougulong

Commonly known as the fourth generation of red maple, it is a variation variety selected by asexual breeding technology on the basis of the first variety.

It takes a long time for red leaves to turn green in summer. Dense branches, the phloem and xylem of new shoots are purple. The fibrous roots are purplish red. The annual flowering period is 3-4 times, in the middle of spring, the initial flowering period is in the middle of February, the full flowering period is from late March to late April, and the annual flowering period is 105 to 130 days. In this class, according to the characteristics of leaf size, branch density and flowering period, it can be divided into seven types: long leaf through grain red, dense branch through grain red, sparse branch through grain red, thin leaf through grain red, spotted leaf through grain red, winter bright through grain red and Voldemort through grain red. In each type, 25 varieties are divided according to the color and petal morphological characteristics. This variety has the longest flowering period, rich flower patterns, the brightest colors, dense branches and easy modeling, and can be used to create colored sculptures and small and medium-sized shrub balls.

In this class, according to the characteristics of leaf size, shape and branching angle, it can be divided into four types: big leaf red, pointed leaf red, Voldemort red and warped leaf red. In each type, it is divided into 7 varieties according to obvious characteristics such as color and petal shape. This variety has large and ruddy leaves and high ornamental value. The four varieties' Dayehong',' Dayemeihong',' Dianyehong' and' Dayejuan Petal Red' have moderate branches and grow rapidly, which are suitable for cultivating large-scale colored sculptures and shrub balls.
