About Box elder
Acer negundo, commonly known as box elder or ash-leaved maple, is a fast-growing, wide-spreading tree native to North America. It is characterized by its unusual pinnately compound leaves, atypical for a maple, giving it an ash-like appearance. It's ideal for large gardens, parks, or as a shade tree in areas where rapid establishment is desired and intensive maintenance is not a priority.
Native range
North America
Care tips
This maple is highly adaptable and tolerates a wide range of conditions, preferring full sun to partial shade. Watering should be regular during the first few years to establish the tree; afterwards, it tolerates drought periods, though occasional summer watering will promote better growth. It adapts to almost any soil type, even poor or clayey, as long as it has good drainage. A common mistake is planting it in confined spaces, as its rapid growth and ultimate size can lead to issues.
