Difference between海棠 and 四季海棠
In courtyard plants,海棠 is highly favored for its rich variety, among which 四季海棠 is particularly special. Behind the seemingly similar names lies a significant difference from genetics to morphology. This analysis from three dimensions - genetic tracing, plant characteristics, and maintenance points, helps gardening enthusiasts accurately identify these two plants.
Comparison of Plant Genetic Tracing
Rosaceae vs. Begoniaceae
Traditional海棠 belongs to the Rosaceae family, Malus genus, including species like weeping海棠 and Xifu海棠, which are woody varieties with wooden stems that can grow up to 8 meters. 四季海棠, on the other hand, belongs to the Begoniaceae family, and as a herbaceous plant, it reaches a maximum of 30 centimeters, with its fleshy stem characteristics determining its shade tolerance.
Genes Determine Morphology
Rosaceae海棠 branches are cylindrical and lignified, with glossy, leathery leaves. Begoniaceae varieties have semi-transparent, fleshy stems and thin, translucent leaves, and this structural difference directly affects the cold resistance and cultivation methods of the two.
Differences in Plant Morphological Characteristics
Comparison of Trees and Herbs
Woody海棠 has a distinct main stem and can be cultivated into a courtyard landscape tree, creating a sea of flowers when blooming in early spring. 四季海棠 is丛生, suitable for potted landscaping, and its year-round blooming feature makes it an optimal choice for windowsill greenery.

Flower Morphology Atlas
海棠 flowers have typical Rosaceae characteristics, with a 5-petal flower shape and a diameter of 3-5 centimeters, ranging in color from snow white to crimson. 四季海棠 flowers are only 1-2 centimeters, with a semi-double petal shape and waxy petals that remain vibrant even in low light.
Analysis of Cultivation and Management Points
Difference in Light Requirements
Woody海棠 requires full sunlight, with 6 hours of direct sunlight daily to ensure flowering quality. 四季海棠 can grow normally under scattered light, and direct sunlight can easily cause leaf burns, making it suitable for indoor windowsill care.
Temperature Adaptation Range
Malus genus海棠 can tolerate -15℃ low temperatures, while Begoniaceae varieties need to maintain temperatures above 10℃ for overwintering. This characteristic determines that in the northern regions, 四季海棠 needs to be overwintered indoors, while woody海棠 can be cultivated outdoors.
Through systematic comparison, it is evident that there are essential differences between the two types of海棠 in terms of genetic composition and cultivation methods. Mastering the characteristics of the family can design targeted planting plans: woody海棠 for creating the main courtyard landscape, and 四季海棠 for constructing a continuous flower environment. Correctly identifying the differences between the two can perfectly match plant characteristics with the cultivation environment.
