Cornus officinalis is a deciduous shrub or small tree belonging to the genus Cornus of the Cornaceae family. It is mainly distributed in East Asia, including China, Japan, South Korea and other places. This tree species is not only widely planted for its ornamental value, but is also valued for its fruits that have certain medicinal value.

 

Features and appearance

Tree shape: Dogwood is usually about 5 to 10 meters tall, with a round or broadly oval crown.

Bark: The bark is grey-brown and will develop longitudinal cracks as it ages.

Leaves: The leaves are opposite, oval or egg-shaped, with serrated edges. The leaves are dark green and turn red or purple in autumn.

Flowers: Small yellow flowers bloom in spring, densely packed into corymb-shaped inflorescences.

Fruit: The fruit is a bright red berry, which matures in autumn and has high ornamental and medicinal value.

Growth environment

Distribution: Dogwood is mainly distributed in temperate regions of East Asia, especially in mountainous and hilly areas.

Altitude range: This tree species usually grows in areas between 100 and 1500 meters above sea level.

Soil and Moisture: Dogwood prefers well-drained, fertile, sandy loam soil, but will adapt to a variety of soil conditions. It requires a moderate amount of moisture and has relatively good drought tolerance.

Light: Can grow in full sun to semi-shade, but flowering and fruiting are more abundant in full sun.

Overview of trees absorbing carbon dioxide

Although there is currently no specific data showing the amount of carbon dioxide absorbed by a single dogwood tree, as a deciduous tree, it absorbs carbon dioxide and releases oxygen through photosynthesis, which to a certain extent has a positive effect on improving the environment and mitigating climate change. Generally speaking, trees absorb carbon dioxide from the atmosphere through photosynthesis during growth, and the annual absorption of deciduous tree species may be related to their size, age and growing environment.

 

Dogwood's ornamental value, medicinal value and role in the ecosystem make it one of the important tree species. In autumn, its bright red fruits and changing leaves add a splash of color to the natural landscape.
