But if the rustic box isn't your style? A wicker basket. A silver tray with lower sides. A glass bowl with moss up the sides to obscure the "mechanics" of the arrangement. A decorative ceramic serving dish. I love the subdued green and white look.
Cream and blush roses, scabiosa and astilbe bouquet but adding bright colors: corals, peach, some orange and touches of deep plum but utilizing these colors as neutral tones. Also using these colors as base for floral cluster on garden arch.
