Report an issue with this species
Fraxinus, commonly known as ash, comprises medium-to-large trees, mostly deciduous with pinnately compound leaves, though some subtropical species are evergreen. These trees are known for their strong, elastic wood used in tools and furniture, and some species exhibit attractive yellow-orange to purplish fall foliage. In urban settings, some ash species like White Ash are widely used in landscaping but can be susceptible to pests such as the ash whitefly.
