1. East cuckoo and West cuckoo

Although China is the origin of Rhododendron, there are many local Rhododendron species. However, many of the rhododendrons we watch come from abroad. They generally have two ways to enter China: one is to breed and cross from Japan, and then enter China, and the other is to enter China from Europe. We generally call the Rhododendron entering China from Japan as the East Rhododendron, and the Rhododendron entering China from Europe as the West Rhododendron

Both of them bloom in winter and spring, but the flowering period of dongjuan can be a little earlier, and it can bloom about after new year's day. The Western azalea blooms later and blooms around the Spring Festival

2. Four seasons Rhododendron

In recent ten years, we can often see a Rhododendron species called four seasons Rhododendron in the market, which has no fixed flowering period. Its main flowering period is similar to that of Western cuckoo, around the Spring Festival. In addition, as long as the conservation is reasonable and the environment is appropriate, it can also bloom at other times, but the number of flowers is not as good as the main flowering period. However, when the temperature is above 30 ℃ in summer, it will not bloom again. It can bloom in a cold environment
