Dahlia
Culture Overview of the classification of Dahlias: Dahlias are classified according to their typical traits and characteristics:Dahlias are most various in their flowerform. One of the first notable things is the difference in flowerhead between the single-flowered types and the fully double flowers. On this page you'll find the single and semi double flowertypes. SINGLE-FLOWERED DAHLIAS Dahlias in this group have a single row of petals around the edge of the large open central disc. The petals may overlap one another. |
