Elsa Ken Haeger introduced the ​Royal Haeger Garden Flower-ware line (1953-1963), recognized by the RG prefix in the style number. This range encompassed outdoor-friendly pieces like planters, vases, and more, boasting unique shapes and glazes. Utilizing an innovative ceramic technique, items were both stronger and lighter, earning the tagline "Rings Like Rare Old Porcelain." Elsa's designs embodied ​mid-century modern aesthetics, merging nature-inspired forms with contemporary elements.
