Habit and Form
var. intermedius - This form grows smaller and more densely to 4' tall. Its smaller, dark green leaves add to its appeal as a subject for difficult planting sites. 'Nanus' is similar, but even smaller -- to 2' tall and wider.
'Dart's Gold' - A more dwarf yellow-foliage form, this plant grows to 5' tall and wide with bright leaf color. The strong shading fades to green by summer in warm areas. 'Nugget' is a new selection that is similar, but perhaps superior due to its more dense habit to 6' tall and wide.
'Monlo' (Diabolo®, also listed as Diablo®) - This plant has become all the rage recently in trendy gardening circles. It is similar to the species, except the leaves emerge deep purple. The effect is striking in spring and all season in cool summer areas, but the strong shading fades to green or purple-green in hot, humid climates. It may be pruned harshly each spring to promote vigorous shoots with large, highly-colored leaves.
'Snowfall' - This is a green-leaved form with a more dense habit to 7' tall and wider. It reportedly bears more showy flowers and more handsome foliage traits.
