(Meadow Rue) ‘Cotton Ball’ Thalictrum, commonly known as meadow rue, is a tall and elegant perennial that brings soft texture and airy charm to garden spaces. True to its name, this variety produces delicate, white, cotton-ball-like blooms that float atop slender, dark stems, creating a whimsical display from early to midsummer. It’s fine, lacy green foliage forms a neat clump at the base, adding layered interest and contrast to surrounding plants. Reaching 38–42 inches in height and maintaining a narrow width of 18–24 inches, ‘Cotton Ball’ is ideal for borders, cottage gardens, or narrow spaces that benefit from vertical accents. It grows well in zones 5–8 and thrives in full sun to part shade. Average watering and well-drained soil will keep it happy throughout the growing season. This meadow rue is both deer and rabbit resistant, thanks to its fine, fuzzy texture, yet it attracts pollinators like butterflies and bees. The blooms also make excellent cut flowers, bringing their unique charm indoors for fresh arrangements. A Proven Winners® Perennial, ‘Cotton Ball’ pairs beautifully with companions such as astilbe, echinacea, phlox, Shasta daisies, and Russian sage. Its graceful height and soft floral display make it a standout addition to any perennial garden.
