Selaginella bryopteris

Sanjeevani

An Indian resurrection spikemoss that grows on rocks in the tropical hills, especially the Aravalli range. In the dry season it curls into a brown ball and looks dead, then unfurls and turns green within hours of rain. It is famous in India as sanjeevani, the life-restoring herb of legend. To grow it, give it a wet, warm growing season and then let it dry out, rather than keeping it constantly moist like a rainforest Selaginella.

Where it grows wild

A lithophyte of rocky hill slopes, growing on rock and in thin soil in rock crevices in seasonally dry tropical hill country. It is poikilohydric: when moisture runs out, the fronds roll up into tight brown balls, and they rehydrate, green up and resume growth when rain returns.

The sources describe it only as a plant of tropical hills such as the Aravallis; no elevation range was found. The Aravallis mostly lie between about 300 and 1,000 m.
