Name source:
The plant functional characteristics of leaves enable people to etch various commemorative patterns and characters on their surfaces with hard objects (bamboo sticks and iron wires) and preserve them for a long time, because they rarely shed leaves.
In some countries, these leaves are carved into numbers by them as playing cards. This is also the origin of the signature tree. The black substance around the seeds in the fruit used to be used to fill the seams of ships, so Americans also called him' asphalt apple'. Seeds are bitter, and birds eat them and urge them to spit them out and spread them, so Italians also call them bitter gourd apples. Balsam apples are easy to pollinate because their pistils are exposed. Some people abroad call it "I won"
Flowers and fruits:
There are many colors, pink (early flowering), white (middle flowering) and brown (old flowering) fruits are as big as apples. The black substance around the seeds in the fruit used to be used to fill the gaps between the ship seams. Seeds are bitter. After birds eat them, they are urged to spit them out and spread.
Growing habits:
It has strong adaptability to the environment, slow growth, strong tolerance to sun and shade, heat and cold. Marker trees, including many plants of Cactaceae and Sedaceae, are special metabolites of many succulent plants. The low photosynthetic rate of these plants makes them grow slowly, but they can survive and grow in arid and hot ecological conditions where other plants are difficult to survive. And is easy to maintain.
Main value:
Most plants carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen; Breathe in oxygen at night and release carbon dioxide. On the other hand, acid metabolizing plants in Sedum absorb carbon dioxide and release oxygen at night, so putting a few pots of famous trees in the room at night can supplement oxygen and help sleep. Due to the above characteristics, signature tree has become one of the largest indoor foliage plants in Europe and America.
