Central Texas is not famous for its fall colors. Nonetheless, I went on a hike today to see what I could see.

My search was rewarded with a few splashes of color. I prefer to think that our land isn’t gaudy with its offerings. Its gifts are more subtle and their rarity is what makes them more valuable.

I first came upon a bright red vine in the lower branches of a small tree. It’s a Sevenleaf creeper (Parthenocissus heptaphylla). It’s very similar to Virginia creeper, which has five leaves, but much less common. It’s endemic to the Edwards Plateau region. The leaves are about 2 inches long and bright red – quite striking.

Next, I saw that some of the cedar elms are starting to turn yellow. Here’s a couple at the edge of a woods among Ashe Junipers (Juniperus ashei) and Live Oaks (Quercus virginiana).

This small cedar elm is even brighter. It’s in the middle of a forest and maybe that’s why it’s further along the color change.

Did you know the fall color change is caused by the leaves losing their chlorophyll? The trigger is the reduced amount of daylight in the fall. This causes trees to shut down their chlorophyll production and prepare for winter. The leaves’ intrinsic colors are then able to show, not masked by the chlorophyll’s green.
