About

Tolmiea is a genus of herbaceous perennials in the Saxifragaceae family, known for their palmately lobed leaves that resemble those of a maple. These clump-forming plants are semi-evergreen and thrive in full or partial shade, favouring moist but well-drained soils of various types and pH levels. In late spring and early summer, Tolmiea produces slender racemes of small, inconspicuous tubular flowers, typically purplish or brownish. Suitable for a range of garden settings including cottage gardens, city courtyards, and containers, they are hardy to UK zone H6 and can be propagated by division, seed, or removal of plantlets in summer.

About the genus

Tolmiea is a genus of flowering plants in the saxifrage family containing two species native to northwestern North America. The genus was formerly considered to be monotypic until diploid populations were split off as T. diplomenziesii from the tetraploid populations of T.
