Malus robusta (Robust Apple) is a cultivar of apple tree known for its ornamental qualities. It is not primarily grown for its fruit but rather for its attractive features. Here are some key characteristics of the Malus robusta apple tree:
Size and Growth: The Robusta apple tree is a small to medium-sized tree, typically reaching a height of about 15 to 25 feet (4.5 to 7.5 meters). It has a rounded or broadly spreading form, with branches that often have a somewhat weeping appearance.
Flowers: This cultivar produces beautiful flowers in the spring, adding ornamental value to the tree. The blossoms are typically pink or pinkish-white, appearing in clusters. They are attractive to bees and other pollinators.
Fruits: While the fruit of the Robusta apple tree is not its primary feature, it does produce small, round crabapples. The fruits are usually yellow or orange, and they persist on the tree into the winter months, providing additional visual interest.
Foliage: The leaves of the Robusta apple tree are ovate to elliptical in shape and have serrated edges. They are dark green during the growing season and may exhibit some red or bronze coloration in the fall.
Landscape Use: Due to its attractive flowers, persistent fruit, and overall ornamental appeal, the Robusta apple tree is commonly used as a decorative tree in gardens, parks, and landscapes. It can also serve as a pollinator for other apple trees in orchards.
Growing Conditions: Robusta apple trees prefer full sun to partial shade and well-drained soil. They are generally hardy and adaptable, able to tolerate a range of soil types. Like other apple trees, they require cross-pollination with another apple variety for fruit production.
