The many tall tree-like ones I have seen here have all been leaning markedly or have had other things about their appearance/condition that did not make them come across as fully committed, bona fide trees. I like this species much better hard pruned in spring to remain short and bushy. And without the flowers concentrated mostly in the upper sections of long, straight stems that branch comparatively infrequently.

im in massachusetts. i don’t even know how this happened we’ve not thrown any peach pits or planted anything over there, i noticed it yesterday.

I don’t know if this helps but these are the only 2 pics I have - the quality gets lower when I upload for some reason

no gal.. i meant the first pic.. those trees are not 10 feet tall .. the gate is at least 6 feet tall at the center.. the garage behind is at least 15 feet tall .. and the trees are bigger than both ... my caution is what i could do when i was 20.. or 30 .. and well into my 40s.. is not something i can do today ... and if i had to pay for this type of maintenance.. i could not do it ... but then.. from the first pic.. those peeps arent really worried about budget ... theyll just have the majordomo call the butler and tell him to call the gardener.. who will call the guys who will come do it .. lol ... the problem with finding random pix online.. is you randomly dont know where the planting is.. and it really doesnt matter what the plants in the pic are ... because you will never know if they will grow in your area ... the better post may have been.. what can i use to make tree line like this ... and others have already offered such suggestions ... ken
