About four years ago, a little tree sprang up volunteer in our wild flower garden. Though BBBH demands that I obliterate the walnut trees that come up quite often (yes, squirrels) I persuaded her to let this little plant survive.
It has thrived and is now about eight feet tall. This is the beautiful June display it adds to the garden. Appears to be a rough-leaf dogwood. I think it meets the definition of "wildflower." But if it gets so big as to shade the entire plot, I suspect it will have to go.
For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.--Luke 6:44
