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 'Rave On' is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light.
