The Green Wall Flowering Crabapple (Malus 'Green Wall') is a deciduous tree renowned for its ornamental value. This tree showcases a stunning display of white to light pink flowers that bloom in the spring, providing a striking contrast against its lush green foliage. The leaves are a vibrant green throughout the growing season, turning shades of yellow and red in the fall before shedding. The tree has a rounded, dense canopy that offers excellent coverage, making it an ideal choice for creating a green wall or natural screen. The bark is smooth and greyish-brown when young, developing a more textured appearance as the tree matures. The fruit is small, typically less than an inch in diameter, and varies in color from yellow to red, attracting birds and other wildlife.
