First of all, their species and genera are different, which is the most fundamental difference. Millenium belongs to Liliaceae and Canna, and the second belongs to agave and Dracaena. In addition, the first is bush, the second is tree.
The first kind of plant has no branches or branches are very rare. The flowers are light red, yellow or strong blue, and the shape is similar to an umbrella. The second kind of plant is different. If you look closely, you can find that it has many branches, white flowers and a fragrance. In addition, there are some differences between their roots. The root system of millennials is very developed, and the root of the latter is not as good as it.
This aspect is more interesting. It is said that the liquid contained in millennial wood is colorless and transparent, while the inner part of dragon blood tree presents the color of blood. Maybe the name "dragon blood tree" comes from it.
Many people will think that it must be millennial wood with a long life span, otherwise why take such a name? However, this is not the case. Dragon blood tree is a very long-lived tree, can live to more than 8000 years old. But the life span of millennials cannot be compared with it. How are you? It's very strange.
Although both of them are mainly distributed in the south of China, the distribution of millennials is more south, almost the most South provinces of China, and the distribution of Dracaena is more extensive. Moreover, for the popularity of foreign countries, millennials are more popular than dragon blood trees.
