A hyper-realistic 3D model of yarrow, a common herb found in the wild. The plant features a cluster of small, white or pale pink flowers atop a slender, green stem with feathery, fern-like leaves. The texture should capture the delicate, slightly rough surface of the leaves and the soft, fuzzy appearance of the flowers. The model should include subtle variations in color to mimic natural growth, with some leaves showing slight yellowing or browning at the edges.
