Liaozhong Roses

Liaozhong Roses

Liaozhong Roses are a protected geographical indication product.

　　Liaozhong has a long history of rose cultivation with a wide variety of species. Thanks to its flat terrain, fertile soil, and the unique microclimate formed by the Liao River—characterized by abundant sunlight and moist air—it provides ideal natural conditions for rose growth.

　　Liaozhong roses have formed a complete industrial structure featuring centralized seedling breeding, dedicated planting bases, standardized production, branded products, expert technical guidance, unified supply of production materials, service provision by associations and specialized cooperatives, and market-oriented sales. This has established the county as a nationally renowned rose cultivation base. Over 5,000 local flower farmers grow Liaozhong roses on more than 20,000 acres of land, producing 460 million fresh rose cuttings annually with an output value of 370 million yuan.

　　Currently, both Liaoning Province and Shenyang City have identified Liaozhong County as a production and distribution hub for “rose” fresh cut flowers in their “12th Five-Year Plan” for floral industry development. Especially with the boost from the Fumeilai Flower Market, the industry shows promising development prospects and economic benefits.
