Description

Saxifraga micranthidifolia

Also known as:

lettuceleaf saxifrage

,

mountain lettuce

Scientific Synonyms:

Micranthes micranthidifolia

Description

Saxifraga micranthidifolia is an uncommon and unusual perennial, with large, broad, coarsely toothed leaves that form dense basal rosettes. It produces white flowers in open, delicate clusters atop rigid stems that can grow up to 3' tall. The species is evergreen in all but the colder areas of its range, with leaves that turn from dark green to burgundy in winter.

Cultivation

Lettuceleaf saxifrage is typically found growing along rocky stream banks, and hillside seeps. It prefers open shade or filtered light, and moist to wet soil. It adapts easily to more typical garden conditions, so long as the soil remains consistently moist. The large basal rosettes and tall flowering stems contrast well with ferns and sedges, and combines well with Caltha palustris (marsh marigold). Zones 5-7

Additional Notes

The young leaves are delicious eaten raw in a salad, hence the common names lettuceleaf saxifrage and mountain lettuce.
