Cultivars/Varieties
Dwarf forms (such as 'Compacta') and fastigiate plants (such as 'Fastigiata') are known, but they are rarely available and perhaps best reserved for collectors.
'Cherokee Brave' - Considered one of the best red forms, with deep pink bracts that have a white center. Will grow 15' tall.
'Cherokee Chief' - A popular selection with bracts that are deep red and reddish new growth. The most popular red-pink dogwood.
'Cherokee Daybreak' ('Cherokee Daybreak) - A variegated selection with white-margined leaves that age to pink in fall. Flower bracts are white.
'Cherokee Princess' - This form blooms at an early age, with very large white flowers -- up to 5" across. It blooms heavily and reliably every year. It's always ranked near the top of dogwood evaluations.
'Cherokee Sunset' (Cherokee Sunset) - A red-flowered form with variegated foliage that is marked with pink/yellow. A good performer, with strong growth to 25' tall and disease resistance.
'Cloud 9' - A slow-growing cultivar with white overlapping bracts. Very heavy bloomer that starts producing as a young plant. Shows good cold hardiness.
'Pendula' - This rare form features branches that are strongly weeping. Flower bracts are white.
'Plena' - Somewhat of a catch-all name for double, white-bracted forms.
var rubra ('Rubra') - This variety has flowers that range from pink to reddish with considerable variation in color. Very common in the trade.
'Welchii' - The leaves are variegated with a mixture of green, cream and pink. Flowers are white and the fall color is rose red. It benefits from a location in partial shade.
