According to the plant type, the grade of baiyinshou can be divided into the following three types: spherical type at the top, tower type at the middle, and flat type at the second.
As a succulent plant, the beauty degree of leaves is extremely important, and silver longevity is no exception.
The best leaf type is pelleted leaf; the second is equilateral triangle leaf; the third is isosceles triangle leaf; the last is willow leaf.
Baiyin longevity does not present a state of sub light, but reflects different degrees of light under the light.
The best grade is that the leaves are waxy bright, followed by oil bright and slight bright.
It is called "silver" because of its thick white color with red stripes on the top of its leaves. For this reason, the whiteness of baiyinshou is one of the important conditions to distinguish its excellent species.
The best white is glutinous white, the second is milk white, and the third is face white.
In addition, the area of whiteness is the best, the more the better.
