Cultivars/Varieties

var. biflora - Called the "Swamp Tupelo", this 50' tree is naturally found in swampy areas and is adapted to poorly drained garden situations.

'Autumn Cascades' - Specialty nurseries are beginning to produce this new, strongly weeping form that shows good fall color. Once accepted by horticulturists, this plant may become a worthy addition to the small list of native weeping plant selections.

'Miss Scarlet' - This is a selection notable for its quality foliage (deep green in summer and red in fall) and abundant production of bluish fruit.

'NXSXF' (Forum™) - Selected for its pyramidal habit and dense, glossy foliage, this new cultivar displays good red fall color. It is one of the few standard cultivars of this wonderful native species.

'Pendula' - Probably not as good a form as 'Autumn Cascades', this selection has an irregular slightly weeping habit that benefits from training. The leaves, however, are deep glossy green and show good fall color.

'Red Red Wine' (also listed as 'Red Wine') - New to this country and not commonly available, this cultivar is reportedly notable for the red coloring of the new growth, which becomes more subdued with age.
