The showiest specimens include accessions of common smoketree (C. coggygria) and its cultivars, such as ‘Daydream’ (see two excellent specimens of ‘Daydream’, 749-78*A and B, at the summit of Bussey Hill). American smoketree (C. obovatus) has less profuse “smoke,” but it more than makes up in ornamental value with its outstanding orange to purple fall foliage. ‘Grace’, a hybrid cultivar of these two species, is also an excellent ornamental.
