I have been waiting all year for my Semiarundinaria makinoi to show its characteristic red coloring. The picture is of a first year culm with a full sun exposure. It is only now that the nights have been dipping into the cooler temperatures that the coloring is getting deeper. So it appears that it is the cooler temperatures rather than the sun exposure that brings out the color change. However, only the side facing the sun is turning red, so could both sun and cold be needed? Any thoughts or experience? Eric
Appologies for the picture quality, they were quickly taken on my way out the door to work this morning.

Does cold weather cause culm color change?

I notice very dark culms on nuda. Seems to correspond with cold weather or maybe young culms.
