It makes sense that a larger diameter scape should be stronger. It's a trait that is probably harder to evaluate than it would seem. When you live in an area that tends to have windy conditions much of the time, the evaluation would be much different than from areas with little wind. Today it will reach into the 80sF and officially the wind is steady at 21mph gusting to 27mph. I have never been convinced that any plant really manages stalks for high winds. They do better if those stalks grow in constant windy conditions, but they are not full proof against it anytime. Today's conditions are not particularly unusual or excessively high for my location.
