About Dahlia 'Karma Naomi'

Dahlia 'Karma Naomi' · also called Karma Naomi dahlia, pink decorative dahlia · flowering

Mature size: About 90-110 cm tall and 45-60 cm wide, with blooms roughly 10 cm across.

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

Dahlia 'Karma Naomi' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season.
