Eugster & Märki-Fischer: Anthocyanins in Roses (1991)
Pelargonin (62; see Fig. 8) did not appear in roses in color-determining concentrations until 1929. In other garden plants, such as pelargoniums and geraniums, it had been known for years. However, analysis shows that pelargonin is hardly ever formed on its own, but is accompanied in almost all scarlet roses by cyanin (66). 'Gloria Mundi' is one of the very few roses that contains almost pure pelargonin (Fig. 8).
