Heuchera ‘Plum Royale’ – This improved version of ‘Plum Pudding’ features very large leaves (up to 4″ across) of a rich plum-purple with silvery highlights that are more prominent in winter. This 2009 introduction from Terra Nova Nurseries has pale pinkish-white flowers held on dark 16″ high scapes. Reliably evergreen in coastal BC. Grows 10″ high by 14″ wide. Zone 4.
Heuchera ‘Paris’ – Another Terra Nova introduction with repeat blooming deep rose pink flowers that emerge in early summer and continue right through to fall with deadheading. These can last up to 12 days as cut flowers and are a virtual hummingbird magnet outdoors. The green foliage also has beautiful silvery highlights between the veins. Grows 10-12″ high by 14-18″ wide. Zone 4.
Heuchera ‘Caramel’ – This French introduction was bred from Heuchera villosa and features large variable leaves that emerge a coppery-red and mature to a pale peachy-orange with a purple reverse. It tolerates full sun here in coastal BC and is more tolerant of high heat and humidity. Remove old damaged leaves in early spring. Grows 12″ high by 18″ wide. Hardy to zone 4.
Heuchera ‘Lime Marmalade’ – This sport of ‘Marmalade’ features highly ruffled leaves of bright chartreuse to lime green. It is a mounding evergreen perennial with tiny tan coloured blooms on 16″ high stalks that emerge just above the foliage. ‘Lime Marmalade’ is a great accent plant in mixed autumn or winter containers. Grows 10″ high by 18″ wide. Hardy to zone 4.
Heuchera ‘Black Beauty’ – I find this Terra Nova introduction a lot more interesting than ‘Obsidian’, much in part to its dark purple to near black ruffled foliage which gives off an interesting sheen. It bears white flowers on very tall 24″ high scapes and looks great in planters when combined with golden Creeping Jenny or Carex ‘Evergold’. Grows 10-12″ high by 16″ wide. Hardy to zone 4.
