Many hawthorns have strongly similar characteristics, but our best information identifies this one as Crataegus coccinea. A plant seen in limited quantities here and rarely found elsewhere, it inhabits drier ground and well-drained slopes through its ... range. A small tree, Crataegus coccinea grows to 15 feet and about the same spread. It flowers early in summer or late spring, with flowers giving way to bright, deeply scarlet fruit that persists into late fall (if not eaten). Small birds love this plant and use its two inch thorns as protection.
