Current photos. Neither blooming right now, not sure if they do. Previous owner of this property had been keeping them cut back and I had continued that til this season I wanted to see what they would do. All help appreciated!
first three pics are one plant, last three pics are the other.
Definitely mulberry and "groundsel tree" or Baccharis. The mulberry is most likely a seedling white mulberry, which will have small white or darker fruit for a short season in early summer, once the trees get tall enough. You might be able to graft some better variety onto them, but you will have to police the suckers which will always be trying to take over from it. Both of these are often thought of as weed trees (or shrub, in the case of the Baccharis) and will be difficult to be rid of completely.
