as keeps happening, i was surprised to discover that "crabapple" is a term that encompasses a lot of kinds of apple trees! what we have here is a "pear-leaved crabapple," i think. the fruits, which emerge in the early fall, are less than half the size of a standard apple and not very tasty to humans; they are, however, enjoyed quite a bit by wild animals of all kinds. (raccoons, squirrels, mice, groundhogs, birds, etc.)
this particular crabapple is native to china, so it is also sometimes called a Chinese crabapple.
the profusion of fragrant flowers don't bloom for long - only about two weeks in spring - but while they're here, they're enjoyed immensely by bees. other pollinators are apparently not as fond of them for some reason.
in addition to feeding wildlife with its flowers and fruit, a variety of other bugs enjoy the wood and leaves - beetles called apple tree borers and apple twig borers, apple aphids, apple leafhoppers, for example. crabapples are also enjoyed by SO many moths!
overall a lovely plant; not from around here, but a welcome addition to the yard. its flowers smell really nice, and i personally really enjoy watching a fat little groundhog snacking away on apples.
