As its common name suggests, erect inflorescences of foamy, white flowers with long stamens are lightening up the woodland floor in late spring. Afterwards, the heart shaped, lobed leaves will provide an effective groundcover, they may turn reddish in the fall.
This is the forgotten parent of many hybrids and cultivars of Tiarella; easy to care for and very useful for woodland gardens, naturalistic areas, shaded rockeries.
Germination: most sources recommend to be sown as soon as possible; it seems that the seeds have short viability.
Update – not really, they germinate well if sown up to January at cold (outdoors).
