About Heuchera 'Green Spice'

Heuchera 'Green Spice' · also called Coral Bells 'Green Spice', Alumroot 'Green Spice' · flowering

Heuchera 'Green Spice' is a compact evergreen perennial prized for its silvery-green leaves traced with deep burgundy veins. It thrives in partial shade to dappled sunlight and tolerates a wide range of soils as long as drainage is good. Listed by the ASPCA as non-toxic, making it safe around pets and children.

Mature size: 25-35 cm tall, 30-45 cm wide

Indoor size vs how big it gets in the wild

Heuchera 'Green Spice' grows into a room-scaled plant of roughly 25-35 cm tall, 30-45 cm wide — bigger than a tabletop plant, but not a tree. Indoors and in a pot, expect 25-35 cm tall, 30-45 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 'Green Spice' 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 (e.g. 10-10-10) in early spring as new growth emerges. a light liquid feed at half strength once in midsummer can support flowering, but avoid high-nitrogen feeds that promote lush foliage at the expense of blooms.

When heuchera 'green spice' outgrows the room (or the pot)

Roots circling the pot base or escaping the drainage holes.
