About Heuchera 'Northern Exposure Amber'

Heuchera 'Northern Exposure Amber' · also called Coral Bells 'Northern Exposure Amber', Alumroot 'Northern Exposure Amber' · flowering

Heuchera 'Northern Exposure Amber' is a cold-hardy evergreen perennial bred for excellent winter performance, featuring large, ruffled amber to burnt-orange leaves with silver overlay. It is among the most frost-tolerant Heuchera cultivars, suitable for northern gardens. Creamy white flowers appear in summer. Non-toxic to pets per the ASPCA.

Mature size: 30-40 cm tall, 40-55 cm wide

Watch for — Slug damage: Spring shoots are attractive to slugs; apply slug pellets or a grit barrier as growth emerges in early spring.

Indoor size vs how big it gets in the wild

Heuchera 'Northern Exposure Amber' grows into a room-scaled plant of roughly 30-40 cm tall, 40-55 cm wide — bigger than a tabletop plant, but not a tree. Indoors and in a pot, expect 30-40 cm tall, 40-55 cm wide. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It builds steadily in both height and spread to a medium, manageable size, filling a pot and a corner over a few years.

Growth rate and years to mature

Heuchera 'Northern Exposure Amber' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced slow-release granular fertiliser in early spring when new growth emerges. a single dilute balanced liquid feed in early summer supports flowering. avoid late-season nitrogen feeds, which stimulate soft growth vulnerable to frost damage.
