water and lots of sun. The caudex can reach 20 centimetres or more
in diameter, the vines will reach for 75 centimetres. The deciduous

reproduced both by seeds and cuttings.
The genera name from Greek

referring to the taste of the roots - haven't tried yet. The species
name means 'lying' or 'outstretched' for the growth form.
