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 and a multi-crown habit. 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.
Developed by Terra Nova Nurseries, this series has helped broaden the use of Heucheras to our northern climates and has the added benefit of being heat- and humidity-tolerant. 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 the plant to fail. They grow well in shade and tolerate sun as long as they have adequate moisture, but prefer afternoon shade. This series has good rust resistance.
Northern Exposure™ alumroot works well in mass plantings along borders or edges, in containers, or as an accent among plants with green leaves. Use in woodland, winter, and shady gardens.
Insects, Diseases, and Other Plant Problems: Monitor for foliar nematodes and root weevils. Overwatering or poor drainage can cause root rot. Other fungal diseases such as powdery mildew and leaf spots can occur. Protect from harsh sun to prevent leaf scorch.
