Portulaca grandiflora, Hook. Rose Moss. Fig. 3150. St. slender and terete, prostrate or ascending, not rising over 6-12 in., hairy in tufts at the joints: lvs. scattered or somewhat clustered, short and terete: fls. large (usually 1 in. or more across in the cult, forms), terminal and subtended by clustered lvs., in many bright colors, soon withering: seeds small, metallic-gray or gray- black. Brazil and S. B.M. 2885. R.H. 1877:90. Gn. 45, p. 436. G. 31:719. Said to be perennial under glass. Runs into many garden forms, as: Var. Thellusonii, Hort. (P. Thellusonii, Lindl.), with handsome orange-scarlet fls. B.R. 26:31. R.H. 1852:5. Var. splendens, Hort. (P. Gilliesii, Hook.), light red-purple. B.M. 3064. Var. albiflora, Hort., clear white. Var. sulphurea or Thorburnii, Hort., dark yellow. Var. caryophylloides, Hort., red, striped white. Var. Bedmannii, Hort., clear white and purple-striped. Colors of the cult, portulacas range from pure white to yellow, rose, scarlet, deep red, and almost purple, with many striped forms. There are also many full double strains. The rose moss is most easy of cult, if it is given a hot and rather dry soil. It needs full sun. The seeds require a rather high temperature for germination, and therefore they are sown rather late, near corn-planting time. Sometimes they are started indoors, but usually they are sown directly where the plants are to stand. The soil need not be rich. The plant makes excellent edgings, and is good for growing in dry rock- work. A large patch of it gives a brilliant display of color in sunny weather, but the fls. do not open in dull weather. Seed of the double varieties produces more or less single-fld. plants, unless saved from cuttings of double-fld. plants, but the singles usually bloom earlier than the doubles. Let the plants stand 10-12 in. apart. They are tender to frost. The plant often self-sows, and in some places it persists about old gardens. Portulaca grandiflora was first described by Hooker in 1829 in the "Botanical Magazine." The fls. were described as "orange-colored, or of a very bright reddish purple." The plant was "discovered by Dr. Gillies, growing in light sandy soil, in various situations between the Rio del Saladillo, or western boundary of the Pampas, and the foot of the mountains near Mendoza. On the western side of Rio Desaguardero plants were in great profusion, giving to the ground over which they were spread a rich purple hue, here and there marked with spots of an orange color, from the orange-colored variety which grew intermixed with the others."
