The light green growths you see in this image are this year’s new growth on Smilax laurifolia. It’s making lots of strong new growth this year, and as you can see in the image it’s having its way with the crepe myrtle. The area caught in this image is at about the 12'-15' level. Were you to look at the top of the crepe myrtle, you would see the topmost strands of the vine waving in the breeze. It has just about reached the size where I’ll be comfortable cutting it for house decoration.
