HeHeHe Caliche tolerance, good one Linda. Where we live in AR it might as well be caliche -- 1" down and you hit solid rock. Never thought a pick axe would be my primary planting tool.
Nurseries probably have an assembly line and they throw out a bunch of tags and say, "Stick 'em in the plants." Full sun for a plant in Wisconsin might be something entirely different than full sun in Arizona.
Great photo Sue.
