The rhizome of woody plant will form a large number of xylem during growth.
According to the plant height and branch position, we can divide woody plant into tree (Arbor), Bush (shrub) and half shrub (subshrub).
The tree (Arbor) has a height ranging from 6 meters to tens of meters, with obvious trunk.
Bush (shrub) has no obvious trunk, which is clumped and relatively short.
In addition, the shape of half shrub (subshrub) is similar to that of Bush (shrub), but the upper branch is annual, and it will wither in winter.
What are the characteristics of woody plant?
Woody plant refers to a strong plant whose roots and stems form a large number of xylem due to thickening and growth.
Moreover, most of the cell walls of woody plant are lignified.
In addition, we can classify woody plant according to the height of the plant and the location of branches.
We can roughly divide woody plant into tree (Arbor), Bush (shrub) and half shrub (subshrub).
Moreover, different types of woody plants have different characteristics.
Tree (Arbor) refers to trees with large height, usually ranging from 6 meters to tens of meters.
We can divide trees (arbors) according to height.
We divide the tree (Arbor) into Wei Qiao (more than 31 meters), Da Qiao (21-30 meters), Zhong Qiao (11-20 meters) and Xiao Qiao (6-10 meters).
The root of tree (Arbor) has an independent trunk, and its crown and trunk are clearly distinguished.
Bush (shrub) refers to the trees that have no obvious trunk, are in a clump state and are relatively small.
We usually divide bush (shrub) into flower viewing, fruit viewing, branch viewing and so on.
Moreover, Bush (shrub) is generally a broad-leaved plant, including rose, peony, Rhododendron, rose, winter jasmine (Jasminum nudiflorum), etc,
We can also see some coniferous bush (shrub), such as Formosan juniper (Juniperus formosana).
The shape of half shrub (subshrub) is similar to that of Bush (shrub). Its plants are relatively short, mostly below 5 meters.
Moreover, many branches with similar thickness will grow at the base of half shrub (subshrub).
Different from bush (shrub), only the branches in the lower half of half shrub (subshrub) are perennial and protected by cork tissue.
But the upper part of the half shrub (subshrub) is annual.
In the cold winter, the upper branches of half shrub (subshrub) will die.
So we often cut off the branches on the top of the half shrub and use them as firewood.
