    Dahlia merkii and D coccinea died back in September/October, my hybrid dahlias died back in November. However in the garden D excelsa, D campanulata are still in good green leaf although flowers finished, but D imperialis is defoliated and partially blackened. In the cold greenhouse D imperialis is struggling, but the other species dahlia in there are still in leaf even if flower buds have blackened.
