In California, Florida, and other places South, there is a large business done in growing Pampas Grass for the sake of the plumes. The Florida Dispatch gives the following method of preparing them in that section: "Cut plume stalks at least two feet long, just as soon as the end of the plume shows through the sheath; strip off all the outer integuments down to the plume, very carefully, and spread the plumes on clean papers in the full glare of the sun for a few days, or until they expand fully. Then keep them in a dry place, free from dust".
