Scraps of fabric typically compose a quilt, but in an inventive display at Iowa State University's Reiman Gardens, colorful patchwork designs were created entirely with flowers and foliage. Ed Moran, the assistant garden superintendent at Reiman Gardens, transformed existing 15×15-foot trial beds into fanciful quilt-block gardens that energized a spacious field of green. Wind and the weather—critical concerns to pioneers living on the prairie—inspired many quilt patterns. This Double Pinwheel block, which was popular during the 1930s, is one such design. Moran chose yellow and red cockscomb (Celosia) for their feathery plumes that add a striking textural quality to the block. Together, they create a vivid and playful pinwheel pattern set off by a lush lavender background of low-growing blue flossflower (Ageratum).
Mark the quilt pattern you have sketched on graph paper using stakes and string. Arrange the potted plants to fill the marked-off sections, placing the plants slightly closer than their expected spread at full growth.
Working on one section at a time, plant each plant individually. Periodically stand back to check that your planting is even. When planting is complete, remove the stakes and string, and water the plants.
Maintain the shapes in your growing quilt. Trim plants that spread out of bounds. If one area appears drier than others, give it a little extra water. Deadhead as needed to keep the colors vibrant.
