Design notes: The central cone of the flower creates an interesting texture that stands out among softer blooms, adding depth and visual intrigue to designs. The daisy-like form introduces a classic, natural shape that works well in both structured and loose, garden-inspired arrangements. It pairs beautifully with wildflowers, grasses, and seasonal foliage, enhancing its versatility.
Purchasing hints: Purchase when the blossoms are newly open. Stems and foliage should be fresh and turgid.
Conditioning: Remove all foliage that will be below the water line. Cut under stem ends with a sharp knife. Hydrate in a solution of water and commercial floral food for two hours before storage or usage.
