Heuchera ‘Velvet Night’ – This Proven Winners selection features deep purplish-black foliage that emerges bright plum and is accented with a pewter overlay which shows off the darker veining. It was originally introduced by Terra Nova and produces sprays of cream flowers in summer. Looks great in combination with gold-leaved Hosta. Grows 8-12″ high by 18″ wide. Zone 4.
Heuchera americana MARVELOUS MARBLE – A seed strain with foliage that emerges primarily purple in spring, matures to green with purple veining and then develops a lovely silver overcast. It bears tiny creamy-white flowers in late spring on scapes that rise 8″ above the crown. The cut stems look good in flower arrangements. Grows 12″ high by 16″ wide. Zone 4.
Heuchera DOLCE ‘Licorice’ (syn. ‘TNHEU044’) – Another Proven Winners selection that is quite cold hardy and sun tolerant. DOLCE ‘Licorice’ features glossy evergreen foliage of burgundy-black (that emerges deep plum) with a purple reverse and light silver mottling. It bears small white flowers from late spring to early summer. Grows 8-12″ high by 16″ wide. Hardy to zone 4.
Heuchera sanguinea ‘Firefly’ (syn. ‘Leuchtkafer’) – This is one Heuchera that is planted more for its vibrant deep red flowers (which attract hummingbirds May to July) than it is for the foliage. The scalloped leaves form a tight green mound that hugs the ground and works well in perennial bed foregrounds. The blooms are also fragrant. Grows 12″ high by 12-16″ wide. Z4.
Heuchera DOLCE ‘Blackberry Ice’ – This villosa hybrid is a Proven Winners introduction and features iridescent new growth that emerges purple with darker veining. These develop a heavy silver overcast as they mature which nicely contrasts the reddish-purple reverse. Cream flowers borne on 20-26″ high scapes are produced midsummer. Grows 10-12″ high by 18″ wide. Zone 4.
