Identification clue 1

Rounded smooth-edged leaves

Identification clue 2

Airy smoke-like flower stalks

Identification clue 3

Small dry fruits

Read the leaves

Simple rounded or oval leaves attach alternately. Purple foliage is common in several selections and does not prove Royal Purple.

More growing details

Read the bark

Gray-brown bark becomes scaly with age.

Fruit & seed

The smoky plumes consist mainly of elongated hairy flower stalks; small dry fruits are scattered within them.

Winter character

Fine alternate twigs need leaves or flower remains for stronger identification.

Origin & place

An introduced garden species or horticultural hybrid; study it as part of WNC landscapes rather than assume it belongs to the native mountain flora.

Compare with American smoketree

Related species overlap; compare leaf size and shape plus flowering structures with a key, and verify cultivar provenance.
