Heuchera Northern Exposure™ Group
Common Name(s):
- Phonetic Spelling
- HEW-ker-a
- Description
-
The Northern Exposure™ group of cultivars has richly colored, mounded leaves with attractive short flower stalks. It is a member of the saxifrage family (Saxifragaceae). These hybrids were bred from H. richardsonii, a species of the northern US and Canada, giving them exceptional winter hardiness.
Northern Exposure™ alumroots were bred to grow as low as Zone 3. They like rich, well-drained, organic soil, lots of humus and medium moisture. Take care not to bury the crown when planting, as this can cause failure. They grow well in shade and tolerate sun as long as they are provided with adequate moisture but prefer afternoon shade.
Northern Exposure™ alumroots work well in mass plantings along borders or edges, in containers or placed among plants with green leaves as an accent. Use in woodland, winter and shady gardens.
Insects, Diseases, and Other Plant Problems: Protect from harsh sun to prevent leaf scorch. Do not overwater plants as this can cause fungal problems. Good rust resistance.
