Diamond Award

The Tesselaar Diamond Award highlights plants of distinction.

All the plants we offer you are garden worthy but for the prestigious Tesselaar Diamond Award, we select only those plants that stand out from the crowd. The best of the best.

Our criterion is based on their floriferous nature, hardiness, disease resistance, ease of care and their sparkle of exceptional beauty.

Diamond Award plants are exceptional, because like diamonds, gardens are forever.
