Get to know this plant.

Identification clue 1

Long finely toothed leaves

Identification clue 2

Drooping sprays of tiny white bells

Identification clue 3

Persistent dry capsules

Read the leaves

Long simple leaves taper toward the tip and have fine teeth; red autumn color is beautiful but not diagnostic.

More growing details

Read the bark

Older bark is deeply furrowed, with chunky longitudinal ridges.

Fruit & seed

Small dry capsules remain in drooping branched sprays long after flowering.

Winter character

Persistent fruit sprays and deeply furrowed bark make a helpful winter pair.

Origin & place

The species occurs naturally in the southern Appalachian region; a planted specimen is not evidence of wild local origin.

Compare with Black cherry

Both may have long toothed leaves; sourwood's branched sprays of capsules differ from cherry's fleshy fruits.
