Geum 'Scarlet Tempest' · also called Scarlet Tempest avens · flowering

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 grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Geum 'Scarlet Tempest' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season.
