Ambrosia Maple: Unique Character and Beautiful Natural Contrast

Ambrosia Maple is not a separate species, but rather maple wood—most commonly Acer rubrum (Red Maple) or occasionally other soft maple species—that has been naturally marked by ambrosia beetles. These beetles create distinctive gray, brown, and sometimes bluish streaks as they tunnel through the wood, introducing harmless staining fungi.

For woodturners, Ambrosia Maple offers a combination of light, clean background color with dramatic natural streaking that makes every blank one of a kind.

Species Information

• Common species: Acer rubrum (most common), occasionally other soft maples
• Common name: Ambrosia Maple
• Native region: North America
• Family: Sapindaceae
• Janka hardness: Approximately 700–950 lbf (varies by species)

The ambrosia markings do not significantly weaken the wood. They are cosmetic and highly valued for their appearance.

What Causes Ambrosia Figure?

Ambrosia beetles bore into freshly fallen or stressed maple trees and carry a specific fungus with them. The fungus stains the surrounding wood, creating streaks that follow the beetle tunnels.

Key characteristics include:

• Gray, brown, or bluish streaks
• Small pinholes from beetle entry
• Natural, organic patterns
• Random distribution

These markings are completely natural and vary from subtle to bold.

Color and Appearance

Ambrosia Maple typically features a light base color with contrasting streaks.

Color characteristics include:

• Cream to pale tan background
• Gray to brown streaking
• Occasional bluish or black lines
• Smooth, clean grain
• Moderate natural luster

The contrast between the pale maple and darker ambrosia lines gives it strong visual appeal without being overpowering.

Grain Structure and Texture

Ambrosia Maple generally has a straight grain with a fine to medium texture.

Grain characteristics include:

• Smooth, even grain
• Fine texture
• Uniform surface
