Saxifraga stolonifera

Saxifraga stolonifera is a perennial flowering plant known by several common names, including creeping saxifrage, strawberry saxifrage, creeping rockfoil, as well as the quite ambiguous "Aaron's beard", mother of thousands, roving sailor, wandering Jew, and strawberry begonia or strawberry geranium (it is neither a begonia nor a geranium). It is native to Asia but has been introduced to other continents, mainly for use as an ornamental. A popular garden flower, it has attractive white blossoms with distinctive pointed petals and bright yellow ovary. S. stolonifera also sees use as a houseplant. Its creeping green foliage makes a good groundcover. The plant spreads via threadlike stolon (runners), with plantlets taking root in the vicinity of the mother plant. It is hardy to USDA zone 5.

The foliage is occasionally used fresh or cooked in Japanese cuisine. It was also used as an herbal remedy in Classical Japan. It contains quercetin which has been shown to have anti-cancer activity in vitro.
