Unlike other Dahlias, this variety is admired for its bright color and somewhat smaller, more delicate blooms. It’s a great choice for adding a splash of color to gardens and floral arrangements.

How to Care for Dahlia Coccinea?

  2. Soil: They prefer well-draining soil. A mix that includes compost or organic matter can help improve soil structure and fertility.
  3. Watering: Regular watering is crucial, especially during dry spells. However, avoid waterlogging the soil as it can lead to root rot.
