Heuchera 'Green Spice' (Coral bells)

'Plum Pudding' heuchera makes an excellent foliage plant for sunny to partly shady gardens. This cultivar has a mounded form. Its small white flowers, which bloom in early summer, are not as impressive as the foliage, but they do add a second level of interest. The foliage of 'Plum Pudding', with its silvery overtones, is not as dark as that of other burgundy heucheras. In mild winters, the foliage will persist if you provide adequate moisture to the soil. -Lou Anella, Regional Picks: Southern Plains, Fine Gardening issue #127

This heuchera cultivar has very dark (almost black) plum or purplish leaves and greenish white, bell-shaped flowers in late spring and early summer.

In the past decade or so, dozens of new Heuchera cultivars have appeared sporting many combinations of foliage color. While all are delightful foliage plants, the lighter-colored varieties seem best adapted to shade. The most popular of these is Dolce® Key Lime Pie. With its bright gold–chartreuse leaves, this gem of a plant will light up a dark, shady area. -Tom Nelson, Regional Picks: Northern California, Fine Gardening issue #127

This hybrid has petite green-and-cream variegated foliage with a hint of pink on the undersides. It produces chartreuse and apple green bicolored bracts on airy stems.
