The Magic of Waterlily Dahlias Exploring the Alluring Characteristics of This Unique Bloom

Waterlily dahlias captivate gardeners and flower enthusiasts with their enchanting shape and delicate charm. Their petals curve gently inward, creating a soft, cupped center that resembles the serene beauty of a waterlily floating on a pond. This distinctive form has earned a special place in the world of dahlias, inspiring admiration and curiosity alike. Recent updates from the American Dahlia Society (ADS) have expanded the classification of these blooms, recognizing even the tiniest waterlily forms, known as Micros. This post explores what makes waterlily dahlias so unique, their classification, popular varieties, and what to look for when appreciating or growing these stunning flowers.

What Defines a Waterlily Dahlia?

Waterlily dahlias stand out because of their petal structure and bloom shape. The petals have rounded tips and curve slightly inward toward the center, creating a flat, saucer-like appearance. This cupping effect gives the flower a delicate, elegant and inviting.

The bloom’s depth can be shallow, never exceeding half the diameter of the flower, which helps maintain its flat profile. Preferred bloom positioning is at a 45-degree angle at the end of the stem, though some may face flat or straight up. This positioning enhances the flower’s graceful presentation, making it ideal for floral displays and garden beds.

The American Dahlia Society describes the waterlily form as having:

• Outer petals with rounded tips slightly cupped inward

• A flat, saucer-like bloom shape

• Open-faced layers of petals for a delicate look

• Bloom depth less than half the diameter

• Preferred bloom angle at 45 degrees, but flat or top-facing is acceptable

• waterlily dahlias are classified under the 7300's, where "73" indicates the waterlily form and the last two digits represent the color.

  
  

New Recognition for Micros in Waterlily Forms

A recent update from the ADS has introduced a new classification for Micro waterlily dahlias. Micros are blooms under 2 inches in diameter, and this is the first time they have been officially recognized in the waterlily category.

Now, Micros fall under the 7400 series. Currently, only two Micro waterlily dahlias are recorded in the ADS classification system:

• Etolie De Wensel

• Suitzus Julie

  
  

This new category opens the door for collectors and growers who appreciate miniature blooms with the same enchanting waterlily form.
