This 30cm cylinder from IDEALIST™ is defined by thoughtful craftsmanship: a generous 2cm-thick rim frames a 26cm inner opening, lending structural integrity and a sense of grounded permanence. Finished in deep charcoal grey light concrete, its matte surface absorbs light with quiet sophistication - never harsh, never fleeting - while the recessed octagonal panel introduces subtle rhythm without ornament.With 21 litres of well-drained capacity, it accommodates a single dwarf box, compact rosemary, alpine succulent or seasonal perennial with room to thrive. Its balanced proportions make it ideal for kitchen steps, balcony rails or clustered arrangements where elegance lies in proportion, texture, and restraint.Frost-resistant and built to endure British weather, it ages with dignity - proof that even the smallest planters can carry great intention, and that true garden style begins with the details you feel as much as you see.
