Giant Oak Leaves

Down beneath the cedar canopy, you can find a few oaks that have been sheltered from the cold nights and frosts that we’ve had recently. The leaves look as those on the exposed trees looked two weeks ago. Walking through this tiny shadowed woods is like taking a short trip back through time. This will be my last seasonally colorful foliage this fall. It’s a shame the overcast sky and towering cedars make it so dark here. I’d love to see these leaves have one more sparkle in the sunlight.

The really neat thing about these leaves is their huge size. Leaves growing in shaded areas tend to grow larger in order to make better use of the filtered sunlight they receive. These are the types of leaves I used to collect for elementary school leaf collection projects. The teacher would give us mimeographed sheets with an outlined block in which we were to attach our leaves. Other kids would turn in their projects as a neat little book of pages displaying their leaves. I would turn in a stack of paper with leaves sticking out the edges all the way around. I lost points for neatness and then more points for arguing and finally, a trip to the office.

This looks like the leaf of a Red Oak, Quercus rubra. Most oak species display a wide range of leaf shapes, sometimes on the same tree. This makes leaves unreliable as a sole means of identification.

Buds can help you narrow the possibilities and these buds are pretty Red Oakish. Bud characteristics can also blend between species, so once again they cannot be used as the sole identifier. If you can get some acorns, the identification becomes much easier, but these young trees don’t have any acorns. Bark can also be used to fix an identification, if you’re dealing with an older tree.

Well, I can live without being 100 percent sure on my identifications. I once watched two professional botanists argue over the identification of a tree in the red oak group. I would have believed either one of them without question, but in this case everyone walked away confused. Anyway, I can still admire the beauty of the leaves.

Red Oak


At a distance, this looked like a dark mushroom cloud billowing up in the middle of my woods. I mentioned before how color change and leaf drop can call attention to individual trees. This is an excellent example. Even though I had a good idea of which tree this was, I decided to head back into the woods and verify my suspicions.


Here it is. A nice tall Red Oak, Quercus rubra. I’m surprised this tree wasn’t cut before I bought it. There must not have been a market for Red Oak the last time this woods was logged. I don’t believe they would have missed it by accident.


It’s a long way up the trunk before you see any lateral branches. That’s an indication that the tree was growing in close company with others as it put on height. Removal of these neighbors as part of the logging operation, allowed the tree to send out side branches and expand its canopy.


The trunk is about three feet across here. Expansion of the tree canopy and development of more leaf area allowed the tree to increase its growth rate. This tree shows every sign of being healthy and barring accident, should develop into a monster. Too many big ridgetop trees like this fall prey to lightening strikes. I hope this guy’s lucky.


A lot of acorns fall from this tree. All the leaves in that wide canopy make this tree a mast machine. Deer, turkeys and squirrels don’t let those acorns sit around for very long.
