What Is Box Elder Wood
Box elder wood is a type of hardwood that comes from the box elder tree, specifically the Acer negundo species.
It's a fast-growing tree that can thrive in a variety of environments, including wetlands and floodplains.
Box elder wood is known for its distinctive interlocking grain pattern, which can be challenging to work with.
The wood is relatively soft, with a Janka hardness rating of 490 pounds per square inch, making it more prone to scratches and dents.
It's also relatively lightweight, with a density of around 0.55-0.65 g/cm³.
Despite its challenges, box elder wood can be stained and finished to reveal a beautiful, rich color.

Working with Box Elder Wood
Working with Box Elder Wood is a delight. The wood is soft enough to be easy on cutting edges, bits, and abrasives, making it perfect for kids to work with or for those just starting out.
Box elder is a low-cost wood, with lumber running less than $2 per board foot for FAS. You can also find spalted boxelder, with its raspberry streaks, highly prized for accent work and turnings.
To work with box elder, keep in mind that it can burn easily, so use only sharp cutting edges. A constant feed rate is also essential to avoid burning, especially when ripping or routing.
Here are some additional tips to keep in mind:
- Use a sharp cutter when hand-planing to achieve a smooth surface.
- Speed up the rpm rate when drilling box elder, and raise the bit occasionally to clear out chips and reduce the chance of burning.
- Use a backing board to avoid tearout of this comparatively brittle wood.
- Predrill holes to avoid splitting when nailing or screwing.
- Apply a ribbon of glue on each joining surface, then press them together to spread the glue, and finally clamp and clean up all squeeze-out.
Uses in Woodworking
Boxelder wood is a great choice for woodworking, especially for projects that require a light wood. It's perfect for making boxes, carvings, turnings, treenware, toys, and simple furniture or storage projects.
The wood's light color makes it ideal for accent work and turnings, especially when it has its distinctive raspberry streaks, known as spalted boxelder. This type of wood is highly prized for its unique appearance.
Suggestion: Yellow Light

Caring for Live Edge Slabs
Box elder wood requires regular maintenance to ensure it remains in good condition. Box elders deteriorate over time.
To keep your live edge box elder slabs looking their best, keep the wood dry at all times. This will help prevent insect infestation, which can be a major issue with this type of wood.
Identifying Box Elder Wood
Box elder wood is relatively lightweight, weighing in at 27 pounds per cubic foot dry, which is similar to white pine and the lightest of the American maples.
Its close-grained and creamy white color can make it a great choice for woodturners who want to create bright bowls, slender goblets, and attractive platters.
The wood is also known to be brittle, so it's essential to handle it with care.
Box elder trees can sometimes contain wood with raspberry-colored streaks and flecks, which are caused by a pigment from a fungus called Fusarium negundi.
Common Names
Box elder has numerous common names, and it's not hard to see why - its wood and leaves have similarities to other familiar plants. One of its most well-known names is "box elder" itself, based on the similarity of its whitish wood to boxwood.
The name "boxelder maple" is also used, highlighting the similarity of its pinnately compound leaves to those of some species of elder. Other common names include "Manitoba maple", "ash-leaf maple", and "cut-leaved maple", each referencing a different characteristic of the tree.
Box elder is sometimes mistaken for poison ivy, due to the superficial similarity of its leaflets. However, it's worth noting that box elder has an opposite branching pattern, which is different from the alternating pattern of poison ivy.
In the United States, box elder is commonly known as "box elder", "boxelder maple", "ash-leaved maple", and "maple ash". It's also referred to as "river maple", likely due to its preference for riparian environments.

Identification
Box elder wood is often confused with other types of wood, but there are some key characteristics that can help you distinguish it.
Box elder trees typically grow to 40-50' in height and 2-3' in diameter, making them relatively small compared to other types of trees.
One way to identify box elder wood is by its red stain, which is a result of a fungus called Fusarium negundi.
Box elder wood is also characterized by its light weight, weighing in at 27 pounds per cubic foot dry, which is nearly the same as white pine.
Its gray-brown bark can be easily mistaken for white ash, but the furrows on box elder bark run much shallower.
The tree's leaves are pointed and resemble those of white ash, but with more scallops, making them a distinctive feature.
Double seed pods that hang in a V-shape on the branches from early summer on are another identifying feature of box elder trees.
Distribution and Habitat
Box Elder is native across much of the United States, mostly in the east, and south-central Canada. It can also be found as far south as Guatemala.
The tree has been naturalized in eastern China and is listed as a pest invasive species in some cooler areas of the Australian continent.
Box Elder prefers bright sunlight and often grows on flood plains and other disturbed areas with ample water supply. This can include riparian habitats.
In some areas, like parts of the Northeastern United States, Box Elder is considered a weedy species and has increased greatly. This is likely due to its ability to quickly colonize both cultivated and uncultivated areas.
Box Elder can be found in a variety of environments, including disturbed ground, vacant lots, and even in hedges and around houses.
Box Elder Wood Details
Box elder wood is a low-density hardwood, weighing in at only 2.7 pounds per board foot, making it the lightest type among the maples.

Description
Box Elder trees are known for their fast growth rate, with some specimens reaching heights of up to 25 meters tall. They can form impenetrable thickets due to their multiple trunks.
The lifespan of a Box Elder tree is relatively short, typically ranging from 60 to 75 years. However, under optimal conditions, they may live up to 100 years.
The bark of a Box Elder tree is pale gray or light brown, deeply cleft into broad ridges, and scaly. This unique characteristic sets it apart from other maples.
Box Elder leaves are pinnately compound, with three to seven leaflets, making them easily distinguishable from other maples. The leaflets are about 5-10 cm long and 3-7 cm wide, with slightly serrate margins.
Here are some key characteristics of Box Elder leaves and fruit:
- Leaves: pinnately compound with 3-7 leaflets, 5-10 cm long and 3-7 cm wide, with slightly serrate margins
- Fruit: schizocarp of two single-seeded, winged samaras on drooping racemes
Taxonomy
The Box Elder's taxonomy is a bit of a debate among botanists. The Box elder is not in the Elder genus Sambucus in the family Adoxaceae.
Some botanists treat the Boxelder maple as a distinct genus, specifically Negundo aceroides, but this classification isn't widely accepted.
Density of Wood
Box elder wood is classified as a low-density hardwood, weighing in at about 2.7 pounds per board foot.
This makes it the lightest type among the maples, and low-density wood is generally quite brashy, weak, and brittle.
