Growth habit
Osmanthus fragrans likes warmth, strong resistance, high temperature resistance and cold resistance. Therefore, it can overwinter in the open air in the areas south of Qinling Mountains and Huaihe River in China. Osmanthus fragrans likes sunshine, but also can resist shade. In full light, it has lush foliage and dense flowers. In the shade, its branches and leaves are sparse and flowers are scarce.
If potted indoors in the north, it is especially necessary to pay attention to sufficient light to facilitate growth and flower bud formation. Osmanthus fragrans is relatively humid, and it is forbidden to accumulate water, but it also has certain drought resistance.
Osmanthus fragrans is not strict with the soil. Except alkaline soil and low-lying land or soil that is too sticky and poorly drained, it can generally grow, but slightly acidic sandy loam with deep soil layer, loose and fertile soil and good drainage is the most suitable.
