Cycas cycad is a gymnosperm with a trunk about 2 meters high, and its pinnate leaves are obovate in outline, narrowly lanceolate and 75-200 cm long. Cycas is also known as Cycas, Polygonum multiflorum Thunb, Polygonum multiflorum Thunb and Pinus densiflora Thunb. The flowering period is from June to August, and the seed maturity time is 65438+1October. However, Cycas rarely blooms, and generally Cycas will bloom for more than 10 years.

Cycas likes warm, hot and humid environment and is not cold-resistant. I like the environment with plenty of light, and I can tolerate it in the shade; It grows well in fertile, moist and slightly acidic soil. When planting in the open field in the north, warm measures such as straw wrapping should be taken in winter.

The life of cycads can be as long as 200 years. Trees in tropical and subtropical areas of southern China that are over 10 years old bloom and bear fruit almost every year, while Cycas cultivated in the Yangtze River basin and northern areas often do not bloom for life, and a few Cycas will only blossom and bear fruit when the growth environment is good.

The tree shape of Cycas is simple and the trunk is as thick as iron. Feather leaves are clean, smooth and bright, evergreen all the year round, and it is a precious ornamental tree species. In the south, it is planted in front of the yard and in the lawn; Suitable for large potted plants in the north, it is very beautiful to decorate courtyard corridors and halls.
