Abstract: "The roselle is an annual from the Old World Tropics. It is extremely sensitive to frosts, and can at present be grown for its fruit only in tropical and subtropical countries. Being easily cultivated when the climate is favorable, the roselle should be in the garden of every family, and on account of its excellent qualities for making jellies, jams, etc., it is certain to become an important plant in the manufacture of those products. The young stems also make good jelly. For such use the plant can be grown almost anywhere in the North or South. By proper methods of breeding it is possible to obtain strains with larger calyces. Probably earlier bearing races can also be obtained by careful selection of the earliest flowering plants.
