| Identification | This butterfly-bush species has relatively wide and long leaves as in B. davidii. However, it differs in its untoothed leaf margins and granular farinose inflorescence, versus toothed leaves and a non-farinose inflorescence in that more familiar garden species. The flowers are more narrowly tubular than in B. davidii, and most flowers are lavender to purple in color. It is not overly fragrant or a good butterfly attractant, as least as compared to that species. | |
