Southern elm is Sassafras, Lauraceae, Sassafras genus.

Mainly produced south of the Yangtze River in China. Sassafras (Latin scientific name: Sassafras tzumu (Hemsl.) Hemsl), also known as sassafras tree (Zhejiang, Jiangxi), southern tree, mountain sassafras (Zhejiang), green sassafras (Anhui), Tongzi tree, pear fire coax (Fujian), Catalpa tree, catalpa tree (Hubei), brushwood (Fengchuan, Guangdong), rowan tree (Zhenxiong, Yunnan, Sichuan), goosefoot (Yunnan Weixin), half-wind camphor (Guangxi).

Deciduous trees, up to 35 meters in height and 2.5 meters in diameter at breast height. Likes warm and humid climate. It likes light but cannot tolerate shade. Produced in Zhejiang, Jiangsu, Anhui, Jiangxi, Fujian, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Guizhou and Yunnan provinces. The roots, stems and leaves can be used as medicine and are also used in shipbuilding, waterwheels and fine furniture.

Sassafras has yellow flowers in spring that bloom before the leaves. The leaves have a unique shape and turn red in autumn. The flowers and leaves have high ornamental value and can be used for planting in gardens, parks or as street trees. It can be used for afforestation and greening in mountainous areas. :

What is the difference between southern elm and northern elm?

In terms of materials: The scientific name of southern elm is sassafras, while northern elm is authentic elm. There are two types of northern elm, purple elm and yellow elm. Northern elm is comparable to beech from the south. , known as "Northern Elm and Southern Beech", elm wood is not considered a high-end material, and the wood processing is relatively simple.

Wood stability (shrinkage, cracking, deformation, hardness) is stronger than old elm than old sassafras (sassafras is not beech), and new elm is stronger than new sassafras (southern elm); To clarify, old elm may also crack and deform. Even mahogany, rosewood, and rosewood may also crack and deform, but they are relatively stable. After all, it has a lot to do with the environment and maintenance, especially temperature and humidity.

From the perspective of woodworking production: it is divided into production time and production type. If a piece of furniture requires 20 working hours at the normal master level to make, if you want to pursue profits, you can consider using an apprentice and 16-18 working hours to make it. The difference can be imagined.

In terms of production types: purely made by masters, made by master and apprentice together (conventional), purely made by apprentices, these can only be relatively speaking, even if you are a senior master, you can do it even if you are given a short working time. If you don't produce detailed products, even an apprentice can make good products given a long time. This requires you to find a manufacturer with a higher reputation or a larger scale.

As for dryness: the temperature in the south is higher than that in the north. Southern furniture needs to be dehydrated when brought to the north (heating is used in the north in winter), and the cracking and deformation coefficient is higher due to dehydration and shrinkage; the old elm wood in the north is used as a beam. Wood, which has been dried for a long time under natural conditions, will also shrink when exposed to heating in winter, but the coefficient is not large. Because it has been naturally dried under northern conditions for a long time, the probability of deformation is low;
