Osmanthus morphological characteristics
Osmanthus is an evergreen tree or shrub, with grayish-brown bark and yellow-brown branchlets that are hairless. Osmanthus leaves are elliptical or elliptical-lanceolate, with acuminate tips. The petiole is 0.8-1.2 cm long, and can reach up to 15 cm. Cymes are clustered in the leaf axils, with many flowers in each axil. The flowers are extremely fragrant. The corolla is white, pale yellow, yellow or orange-red, 3 to 4 mm long, and the corolla tube is only 0.5-1 mm long. The fruit is slanted, elliptical, 1-1.5 cm long, and purple-black. The flowering period is September to early October, and the fruiting period is March of the following year.
Osmanthus ecological habits
Osmanthus prefers a warm and humid environment and has strong stress resistance; it can tolerate both high temperatures and relatively cold conditions. The average temperature in growing areas is 14-28 degrees. Humidity is extremely important to the growth and development of osmanthus, requiring an annual average humidity of 75%-85%, especially during the young stage and flowering period when water demand is greater. Drought will affect flowering. Generally, 6-8 hours of light per day is required.
Osmanthus relatively prefers sunlight; under full light, branches and leaves grow luxuriantly and flowering is abundant, while in shaded places the branches and leaves are sparse and flowers are few. Osmanthus likes moisture but hates waterlogging, and also has a certain drought tolerance. It is not strict about soil requirements, and can generally grow except in alkaline, low-lying, overly sticky, or poorly drained soil.
Osmanthus is suitable for planting in places with good ventilation and light. It likes a clean and well-ventilated environment, is not tolerant of smoke and dust damage, and fears flooding and waterlogging. If harmed by waterlogging, the root system turns black and rots, the leaves first have scorched tips, then the whole leaf turns yellow and falls off, eventually leading to the death of the whole plant; it is not very cold-tolerant, but compared with other evergreen broadleaf tree species, it is still a relatively cold-tolerant tree species.
