The true “Wild” Roses. The botanical term for wild rose is “species rose”, which means just what it says—a species that occurs naturally, with no help from man—a true “wildflower.” There are over 100 of these worldwide, some native to North America, many from the Orient and Europe. These true wild roses are all single with exactly five petals—never more, and almost all of them are pink, with a few whites and reds, and even fewer that range toward yellow. (By the way, there are now over 20,000 hybrids, with about 200 new ones every year.)
