It grows from a creeping tuberous rhizome, a root-like horizontal stem growing just below the surface of the soil.
From an underground, thick, oblique rhizome, the short, green, succulent stipites arise, in a tufted form, and are crinite with brown, subulate, shining scales.
The plant was regenerated as of next spring, since the rhizome would survive.
More in north, zone 9 and 8, they could be restricted with their rhizome at each winter, to push back spring following.
In those species adapted to dunes or other sandy sites, the rhizome systems play an important role in dune formation and soil stabilization.
The medicinal part of zedoary is its rhizome, a fleshy stem that grows underground.
