How would a Sago Palm do in full shade in Austin, Texas??
I am in FL and I had one in full shade under a tree canopy that loved it there. It may have flushed a little less than its full sun counterparts, but that's all.
I don't know about full shade but I learned that they cannot take full Texas sun!! One of mine almost burned up because I had been told they needed full sun and that's where I put them. Now, I have them in part sun/part shade and they are doing much better.
