Shaggy hedgehyssop is a delicate, flowering plant characterized by its soft, hairy stems and small, lance-shaped leaves. Its subtle, pinkish-white flowers usually bear a singular grace, nestled close to the stem. Thriving in wet habitats, shaggy hedgehyssop has developed a preference for moist soils, which influences its slender form and sparse foliage distribution, an adaptation suited for environments where water is abundant yet competition for sunlight is fierce.
