Reproductive methods
sowing
Purple leaf berberis is easy to bear fruit in the north, so it is commonly propagated through sowing method. After harvesting seeds in autumn, wash the flesh thoroughly and let it dry in the shade. Then, dig a pit in a high and dry area and store the seeds in a 1:3 ratio of sand in the pit. The seeds will be sown in the spring of the following year. This way, the seeds stored in sand have a high emergence rate and are easy to be sown successfully. Autumn sowing can also be carried out after harvesting.
cuttage
There are two methods available: hard branch insertion and tender branch insertion. Take semi lignified branches in June and July, cut them into 10 to 12 centimeters long, leave leaves at the top, and insert them into sand or gravel. Maintain a humidity of about 90% and a temperature of about 25 ℃, and they can take root in 20 days. Combining pruning in autumn, select well-developed and robust branches as cuttings, and plant them in sand or gravel. They can be transplanted out of the greenhouse the following spring.
Ramet
Purple leaf berberis has strong sprouting power and fast growth speed, and the plants often appear in clusters, which can be propagated in separate plants. The branching time can be carried out in all seasons except summer.

Growth habits
Purple leaved berberis prefers cool and humid environments, has strong adaptability, is resistant to both cold and drought, and is not resistant to waterlogging. It also likes sunlight and can tolerate shade, has strong sprouting ability, is resistant to pruning, and can adapt to various soils. It grows better in fertile, deep, and well drained soil.
But when the light is slightly poor or the density is too high, some leaves will turn green. Gardens often use evergreen tree species as block color arrangements, which can be used to decorate flower beds and mirrors. They are important tree species for color block combinations in landscaping.
