It has taken me several years to do this. My yard is shady for the most part. Every once in a while a big tree falls or has to be removed (always for a good reason). Then the area changes. A few years a go I began to concentrate on growing native plants. So I have several throughout my yard. I am slowly removing the non native and invasive plants. That has been a challenge. Rewarding, as I have "rescued" a few natives.
