Common Name(s): Holly, American Holly

Scientific Name: Ilex opaca

Distribution: Eastern United States

Tree Size: 30-50 ft (9-15 m) tall, 1-2 ft (.3-.6 m) trunk diameter

Average Dried Weight: 40 lbs/ft3 (640 kg/m3)

Specific Gravity (Basic, 12% MC): .50, .64

Janka Hardness: 1,020 lbf (4,540 N)

Modulus of Rupture: 10,300 lbf/in2 (71.0 MPa)

Elastic Modulus: 1,110,000 lbf/in2 (7.66 GPa)

Crushing Strength: 5,540 lbf/in2 (38.2 MPa)

Shrinkage: Radial: 4.8%, Tangential: 9.9%, Volumetric: 16.9%, T/R Ratio: 2.1

Color/Appearance: Ideal lumber has a very uniform, pale white color with virtually no visible grain pattern. Knots are common, which can reduce the usable area of the wood. Can develop a bluish/gray fungal stain if not dried rapidly after cutting. Holly is usually cut during the winter and kiln dried shortly thereafter to preserve the white color of the wood.

Grain/Texture: Grain is interlocked and irregular. Medium to fine uniform texture with moderate natural luster.

Endgrain: Diffuse-porous or semi-ring-porous; small to medium pores predominantly in radial multiples of 2-4, commonly arranged in radial rows, moderately numerous to numerous; growth rings may be distinct due to an intermittent row of earlywood pores; rays in variable sizes from narrow to very wide, normal to fairly close spacing; parenchyma not typically visible with lens.

Rot Resistance: Rated as non-durable or perishable, and susceptible to insect attack.

Workability: Can be difficult to work on account of the numerous knots and interlocked grain. Glues, stains, and finishes well, and is sometimes stained black as a substitute for Ebony. Turns well on the lathe.

Odor: No characteristic odor.

Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Holly. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Seldom available for commercial sale, Holly is an expensive domestic lumber, and is usually only available in small quantities and sizes.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Inlays, furniture, piano keys (dyed black), broom and brush handles, turned objects, and other small novelty items.

Comments: Holly is typically used only for ornamental and decorative purposes. It has a fairly large shrinkage rate, with a lot of seasonal movement in service, and its strength properties are mediocre for a hardwood.

Scans/Pictures: As you can see from the pictures below, unlike other light-colored woods, Holly remains light-colored even after a finish has been applied, (assuming a non-yellowing finish was used.)

In my experience, there is no better wood for relief carving. It takes and holds crisp detail, and the absence of pronounced grain means no distraction from the carved contours.
Although multiple boards will need to be joined for even moderately sized panels, the uniformity of color means the joints will be virtually invisible.

I recently finished a sculpture that I made from snow white holly. It’s an absolute pleasure to work with! The pieces I purchased were so white you couldn’t tell the endgrain from the side grain, crazy! Carves and sands especially well and can achieve a natual luster at around 600 grit. Such a wonderful wood.

known as “the whitest ” of all woods , it pretty much holds true to that title , holly comes in several variations …., youpon , big leaf ect.. , I have used both big leaf and youpon holly with great results , although youpon holly rarely exceeds 12″ in diameter at the base , mostly a shrub , but for inlays and small projects it works great.

I had an allergic reaction to this wood. Always remember to test sand woods. (So much sneezing!)

Christopher Braun

I see the sap and leaves are reported else where to cause skin irritation. No concerns about that with the dried wood?

There are actually a few suppliers now that reliably carry very high-grade holly, and it really is quite fabulous stuff (see photo). It is probably not appropriate for me to name any of them here, but a search for “American holly lumber” should return fruitful results.

I’m wondering how much it shrinks in length. Considering using some for columns. Most wood doesn’t shrink much at all in length.

I agree, great website.

Very interesting to note above that cured holly is easier to work, Green Holly leaves an awful gunk on my band saw blade. Does cured Holly do the same?

BTW: This site is awesome! Thanks so much for participating.

I’ve only used dry holly but I had no issues with shrinking or movement once it was glued in place. It’s expensive and hard to come by but if you get the good stuff it’s really ultra white. The description says it’s more of a satin finish but I haven’t had the experience with Tung oil. Sanded to 2000 or higher and it has a beautiful a lustrous glow to it. If you can get it then you should. Fabulous wood and easy to work with. The stripe in the middle of the legs is Holly with only one coat… Read more »

Holly is another one of my favorites. Fine grain is great for holding details and sharp edges.

Is the volumetric shrinkage percent of 16.9% correct? As related to radial of 4.8% and tangential of 9.9%, this seems high.

It doesn’t seem high, it seems low.
4.8% radial and 9.9% tangential shrinkage means a cylinder 10 cm wide and 10 cm tall will be have a volume of 785.4 cm^2 before shrinking, and 641.3 cm^2 after shrinking. That’s an 18.3% volume reduction.

That said, holly is always sold as dried wood, both because of the shrinkage, but also because it’s one of very few woods that’s tougher to work when green. So unless you harvest your own holly, it should not be much of a problem. Just seal it well after forming.
