Boxwood
Boxwood is a broadleaf evergreen shrub with tiny leaves and a thick growth habit, making it an excellent choice for formal hedges. It is valued for its compact, tightly packed leaves, which make it suitable for shaping with garden shears or electric hedge trimmers. These are slow-growing shrubs that seldom grow taller than five feet and are typically cut even shorter. Boxwoods, in addition to being a typical low hedge species, may make wonderful shrubs for foundation plantings. Create not just green borders and living walls, but also magnificent sculptures because of this evergreen shrub with a thick canopy and tiny leaves. This shrub plant is always green all year round. You only need to provide enough water to ensure the plant grows well, but you need to have a regular pruning schedule to shape the plant in the way you want them to be.
Because leaves have a skin membrane and epidermal cells have a thick cutin layer, they have a high resistance to poisonous SO2, Cl, HS, and HF, and they absorb toxic gases to clean the air. Chemicals extracted from the leaf are used to manufacture medication (boxwood extract). Boxwood extract has been used to treat HIV/AIDS and enhance immunity. Boxwood is also used in the treatment of arthritis and as a "blood-detoxifying agent".
