Planting on limestone
I was hoping to turn a section of yard into a native/butterfly/bee area, but the rock is only 3" down.
I spent about 4 hours with a rock bar to get one plant in the ground. I really don't want to repeat that. Building up the soil is troublesome because it is bordered by trees. I don't want to bury the trunk, and there are some surface roots running through the area.
What plants are good at growing at shallow depths or in/on limestone? It does have an irrigation system (very shallow, of course).
ETA-it gets about 8 hours of sun
