Ferns tree

For another filler in an arrangement, consider adding ferns to your cutting garden. These typically need part shade to thrive in the garden. Once you cut and add to a bouquet or tabletop display, the greenery will add fullness, especially alongside taller plants, says Speight. "In particular, the Japanese Painted Fern (Athyrium niponicum) adds a silvery tone that can balance, blend, and soften arrangements as needed," she says. "This particular cultivar grows easily in semi-shaded and damp areas." Ferns typically last as long as the rest of the arrangement, typically between seven to 10 days, as long as it stays hydrated.
