Heuchera 'Tnheuner' NORTHERN EXPOSURE™ Red coral bells
Heuchera
Heucheras – coral bells are undemanding yet striking perennials that have gained popularity thanks to their beautiful foliage and delicate flowers, sometimes appearing in rich inflorescences. They form dense clumps of leaves with a breathtaking range of colours. The genus was named after Johann Heinrich von Heucher (1677–1746), a German physician and professor. It includes around forty species of perennial plants, mostly native to North America, except for H. sichotensis from the Russian Far East. To Europe, heucheras were introduced in the 18th century. their classification can be quite challenging as in the wild, these plants often crossbreed, and their flowers change shape significantly as they mature. That’s why so many breeders are drawn to them – their variable gene pool invites experimentation, and the thrill of discovering something new at the end of a breeding attempt is simply irresistible 😊.
Over the years of hard breeding work Terra Nova® Nurseries from Canby in Oregon, USA, have become a synonym for heucheras thanks to their skilful breeder Janet N. Egger. And when one might think that there’s nothing more to come up with they introduce a whole new series called NORTHERN EXPOSURE™ in 2017. They combine findings of Modern Research breeding station in Manitoba, Canada, and Janet’s ground-breaking hybridizing of h. richardsonii with pelargonium-like foliage. The resulting plants are not only beautiful but also hardier, surviving as much as -40 °C, they are rust resistant and have shorter flowering stems.
NORTHERN EXPOSURE™ Red is a coral bells variety with rich maroon to dark red colour with orange-brown tones. They are orbicular (rounded in shape), shallowly lobed, and exhibit slightly wavy margins. They are evergreen. In spring appear about 35 cm tall, maroon stems holding small, bell-shaped, light yellow flowers. Heuchera is a fast-growing perennial of mounding habit. NORTHERN EXPOSURE™ Red was bred by Janet Egger and patented as PP29420 (USA, 2018) and EU51863 (Europe, 2019).
Coral bells can take almost any soil with ample moisture and good drainage. They do best in partial shade or filtered sun, however, if you make sure they will not dry out you can place them in full sun, too. They can also live in dark shade where their colours will not be too rich, such location is usually best for light coloured varieties. Cut off all leaves in early spring to encourage growth of new foliage. This series is fully hardy to abt. -40 °C (USDA zone 3), and suitable for outdoor pots.
