Malus sp. blossoming crabapple tree IDed by rough, cracked, easily peeled bark; bountiful pink flowers with kind of sweet scent; small overall form; elliptical leaves with mildly serrate leaves. Way too hard to determine the species of crabapple so I’m not going to even try. You could probably do process of elimination but idk if it’s actually possible to determine the exact species on observation alone.
