This charming summer border is a marriage of colors, shapes and textures. Fairly easy to replicate at home, it combines the blue rounded clusters of Agapanthus (Lily of the Nile) with the rich golden-yellow trumpets of Hemerocallis 'Bonanza' (Daylily) and the flat, honey-colored umbels of Achillea 'Walther Funcke' (Yarrow).
