The iconic Willy Guhl “Diabolo” planter—also known as the Hourglass or Spindel planter stands as one of the most recognizable designs in 20th-century garden history. Created in the 1950s for Eternit, the form is defined by its elegant double-cone silhouette: a graceful narrowing at the waist that opens into wide sculptural flares at the top and bottom.
Made from Guhl’s pioneering Eternit fiber cement, each planter features a beautifully aged surface with soft mineral patina, natural lichen, and subtle tonal variation acquired over decades outdoors. The Diabolo’s geometry elevates any planting placed inside it—turning caudexes, succulents, and specimen foliage into sculptural compositions.
These planters are highly sought after for their architectural presence, timeless modernist soul, and ability to anchor a space with quiet drama. Available in multiple sizes, they work beautifully alone or as a mixed-height grouping.
