What flowers are suitable for Nanyang
Located in the transition zone of the north and south climates, Nanyang's unique geographical location creates a golden environment for plant growth. As an important flower cultivation base in the Central Plains, it not only supports the vigorous growth of cold-resistant plants from the north but also features the swaying figures of southern flowers. Mastering the local climate patterns can make courtyard flowers present a splendid view throughout the four seasons.
Adaptability of Nanyang's Climate to Plant Growth
Double Advantage of Temperature and Humidity
An average annual temperature of 15°C combined with a frost-free period of 220 days provides an 8-month growing season for woody flowers such as roses and osmanthus. During the high-temperature summer months, heat-resistant varieties like crape myrtle and hibiscus can be planted to maintain the color of the courtyard.
Analysis of Sunlight Resources
With over 2000 hours of annual sunlight, it is especially suitable for sun-loving flowers like peonies and chrysanthemums. When planning the courtyard, short-growing flowers such as petunias and cosmos can be arranged in well-lit areas.

Deep Interpretation of Rose as the City Flower
Historical and Cultural Origins
Since the Song Dynasty, the cultivation technique of roses in Nanyang has formed a complete system. There are 12 ancient rose trees over a hundred years old, among which the 'Red Dragon Containing Pearl' variety in Wuhou Shrine at Wolonggang is listed as a key protected plant.
Modern Industry Support
The city has built rose gardens and rose gene banks, cultivating 28 varieties with independent intellectual property rights, including 'Nanyang Red'. Annually, it produces 20 million seedlings, accounting for 15% of the national market share.
Comparison of Characteristics of Tree Candidates for the City Tree
Chinese scholar trees have strong resistance to pollution and are suitable as street trees; Ginkgo trees have prominent autumn scenery but grow slowly; plane trees provide shade quickly but require measures to prevent drifting. Experts suggest a mixed planting scheme of catalpa and osmanthus, considering both ecological benefits and ornamental value.
Reasonably mixing trees and shrubs and choosing plant varieties adapted to the local climate can make Nanyang courtyards bloom in three seasons and stay green throughout the year. It is recommended to reserve space for plant growth during planting and regularly improve the soil to let the flowers and plants show their best condition.
