One of the longest‑flowering hardy perennials you can grow
Geranium ‘Rozanne’ is a modern classic — a vigorous, spreading hardy geranium that produces an endless display of large violet‑blue flowers from late spring right through to autumn. Each bloom has a soft white centre and delicate veining, creating a luminous effect that brightens borders in any light.
This variety is incredibly easy to grow: drought tolerant once established, happy in sun or partial shade, and wonderfully low‑maintenance. It forms a relaxed, mounding shape that weaves beautifully through other plants, filling gaps and softening edges with effortless charm. Bees and pollinators adore it, and its reliability has earned it the prestigious RHS Award of Garden Merit.
