some water and some sun. The caudex can grow up to 20
centimetres in diameter, the entire plant to 30 centimetres in

The genera name from Greek
rhaphis; 'beet-root' and akme; 'sharpness' possibly
referring to the taste of the roots - haven't tried yet. The species
name after Karl Ludwig Philipp Zeyher, 19th century German botanist
and plant collector.
