As the seasons progress, the foliage of Epimedium grandiflorum undergoes changes. In spring, the fresh, young leaves emerge, often tinged with red or bronze. During the growing season, the leaves turn green and provide an attractive backdrop for the flowers. In the fall, the foliage can take on autumnal hues, adding to its ornamental appeal.
