French Walnut vs American Black Walnut: What’s the Difference?

If you’re choosing Walnut timber in West Sussex, whether for bespoke furniture, interior joinery or a show stopping table top, chances are you’ve heard of both French Walnut and American Black Walnut. While they’re from the same extended tree family (Juglandaceae), they offer very different looks and working properties – and depending on the job, one may suit you better than the other.

At our Sussex woodyard, we stock both types and see first-hand how they shine in different projects. So let’s break it down and explore the differences between these two heavyweights of the hardwood world.

French Walnut: Wild, Characterful, and Utterly Unique

Often referred to as European Walnut, French Walnut is grown throughout Europe – but French-grown stock in particular is prized for its quality and character. This timber is cut from the Juglans regia tree, the same species as traditional English Walnut.

What makes French Walnut special?

• Wild and varied grain: Expect swirling, irregular patterns, sound knots and fascinating visual movement.

• Colouration: Typically a soft brown with cream sapwood and hints of smoky grey, reddish orange or even a ‘mousey’ tone.

• Texture: More unpredictable grain can mean more attention during machining, but the reward is a truly eye-catching piece.

Ideal for:

• Statement furniture pieces

• Artistic woodworking

• Character-driven interiors

We love French Walnut’s natural quirks – it’s the timber equivalent of a charismatic character actor. In fact, the more irregular and wild the board, the more furniture makers seem to fall in love with it.

American Black Walnut: Smooth, Straight and Stylish

American Black Walnut, or North American Walnut, comes from Juglans nigra and is grown across the US and Canada. It’s known for its darker colouring and more uniform grain.

What makes American Black Walnut stand out?

• Rich colour: Purple-brown to deep chocolate tones throughout, sometimes even edging into black. Minimal sapwood.

• Straight grain: Typically smooth, even and easy to work with. Less figuring than French Walnut, but more consistent.

• Larger boards: These trees grow taller and straighter, meaning wider and longer boards are more readily available.

Ideal for:

• Cabinetry and interior joinery

• Flooring and panelling

• Large-scale projects needing consistency and uniformity

American Black Walnut is a favourite with interior designers and architects for good reason. It brings a sense of luxury and depth to any room and machines beautifully, making it perfect for precision joinery.

Workability: Both Are a Joy to Use

Both French and American Walnut timbers are a pleasure to work with strong, stable and relatively easy to machine or shape. That said, there are a few nuances:

• French Walnut’s wild grain can require extra care when planing or routing – grain direction changes quickly, so tearout is a risk.

• American Black Walnut’s even grain means it finishes well with less fuss, perfect for clean profiles and crisp edges.

• Both species respond well to glues and polishes:  just make sure to pick products suited to higher density, acidic hardwoods.

Whichever Walnut you choose, the end result can be outstanding, it just depends how much character you want in the journey.

Uses for Walnut Timber

Whether it’s French Walnut or American Black Walnut, both species are versatile and well-suited to a wide range of applications:

Popular uses include:

• Bespoke furniture (tables, chairs, sideboards)

• Kitchen cabinetry and built-ins

• Interior joinery (doors, staircases, skirting, mouldings)

• Flooring and wall panelling

• Turned or carved items (bowls, utensils, jewellery)

• Veneer for decorative finishes and musical instruments

• Special commissions or artistic pieces

And yes, we dare you to try it for exterior cladding. We think it would look amazing – and with the right finish and detailing, it could work.
