There are many Ilex species in North America but I don't know how many of them product lumber that is sold as holly. Generally, you will see it listed as Ilex opaca but I don't know how reliable that is.
The tree is slow-growing and usually quite small, so the wood is rare, particuarly in any substantial size, and it is likely to have knots which further reduces the sizes available for some applications. There are occasional trees that are up to 2 feet in diameter and 60 feet high, so there are, rarely, planks available. Many reports say that the tree has to be cut in winter, milled, and put into a kiln almost immediately and dried carefully or the wood will warp and/or develop serious blue-stain and/or turn gray which really ruins the white color that is this wood's claim to fame. BUT ... I am assured by a very knowledgeable sawyer in Illinois that you can cut it in summer and make it come out just fine IF you mill it the same day you cut the tree down and put it somewhere dry.
Fine-grained and nearly devoid of figure, this moderately expensive wood is used mostly for small objects. It is a terrific contrast-color wood that turns well, glues well, and works well in general.
my samples:
sample piece and end grain sold to me as holly / Ilex opaca --- the color is NOT correct; this wood is WHITE, not yellow.
plank and end grain --- the actual wood is not as dingy as it appears here; it is more white, although certainly not milk-white

both sides of a sample plank sold to me as English holly / Osmanthus aquifolia --- actual wood is slightly more pink that what shows up here; the end grain closeup below is very accurate in color

evergreen holly (Ilex vomitoria, listed in the Wood Book as cassena and yaupon) from The Wood Book --- both levels of enlargement are available for each of the 3 views. I note that the specific epithet is "vomitoria" and one of the common names is "emetic holly" and I conclude that SOMETHING about this tree is not friendly to the human digestive track.

bowls by Bryan Nelson (NelsonWood). Bryan fine-polishes his bowls with 1200 or even higher grit sandpaper while they are spinning at high speed on the lathe and then finishes them there with a friction polish of his own devising, thus achieving a shine and color vibrancy that is beautiful to behold. These are all about 6" across.
