#1 a crabapple, malus species?

#2 Prunus serotina?

There used to be a burning bush in same spot that got removed 5 years ago due to virus

Yes to Euonymus alatus. Removal is the best thing for it.

Removal for both ?

That Euonymus is invasive in my area.( NC ) When I moved here I tore out several. I grow the native Euonymus americanus, aka Hearts a Bursting. https://plants.ces.ncsu.edu/plants/euonymus-americanus/

Euonymus alatus is not invasive along the west coast so no need to remove on that account. But if the original planting was removed due to a virus, then this offspring should be removed as well.

OK. I was writing from a position of ignorance ..... again.😉 I thought it was a problem everywhere over there.

The Malus can’t thrive mixed up with the rose. It’s not possible to say how it will turn out, being a seedling. If you have the space you could plant it in an out of the way corner. If you have a fairly relaxed gardening style it might provide a pretty blossom tree with some wildlife value.

Crapapple Malus I will be relocating, although I am not sure what it will look like eventually. But I have a spot for a flowering tree elsewhere if that is what it is. It is too close to the climbing rose and I don't remember planting this.

United States has a general precipitation pattern that breaks down into a summer dry western half and a summer wet eastern half. Making the western half often unsuitable for the frequently occurring invasive spreading onto unirrigated land of various notoriously problematic plants of eastern Asian origin that thrive in the monsoon-like conditions of the eastern U.S.
