Issued by Posta Română in 1968, this elegant Romanian series celebrates the vivid diversity of the Pelargonium genus, popularly known as geraniums. The set of seven values (10 bani to 1.60 lei) depicts different varieties — Pelargonium zonale Ait., Pelargonium peltatum Hort., and Pelargonium grandiflorum Hort. — rendered in fine botanical detail by artist Vlasto against geometric backgrounds. These stamps combine mid-century modern design with naturalistic accuracy, exemplifying Romania’s 1960s floral issues that appealed both to botanists and thematic collectors.
