The Tesselaar Diamond Award celebrates plants of true distinction — those rare gems that shine brightest in the garden. While every plant we offer is garden-worthy, only a select few earn this honour. These are the best of the best, plants that stand out through their abundance of bloom, resilience, ease of care, or sheer, breathtaking beauty. Because like diamonds, a beautiful garden is forever.
