Types of Dahlias


Types of Dahlias Transcript

Hi, I’m Barb from White Flower Farm. I’m here in our Propagation area with these gorgeous Dahlias. You can see all the colors and flower forms. Here in New England, we treat them as an annual, and we dig the tubers up in the fall. There are some areas in the south where you can overwinter them, but they’re a beautiful, beautiful flower and today we’re going to talk about the flower forms.

The Royal Horticultural Society lists 14 official divisions of Dahlias, based on flower type. Today we’re going to show you the basic examples of the range of divisions or types available. This way you can see the options that you have for your home garden. First up, the most popular, the Decorative Dahlia.

Decorative Dahlias have double flowers with flat petals. They grow anywhere from 3-5’ tall, and the blooms can be formal or informal. The Dahlias that are commonly known as dinner plates are in this group. Here’s a great example of two decorative Dahlias: one is a dinner plate - look at the size of it - and here’s another decorative Dahlia. So you can see that just because something’s in the same classification, it doesn’t mean it’s going to be the same size, or even look the same.

The Cactus form of Dahlias have tubular petals, but one of the most popular types is the Semi-Cactus, and they just have a little rolling at the edge of their petals.

There’s a Peony form of Dahlia that has two or more rows of petals, they’re a little bit shorter -- some of them have dark foliage.

Another mid-sized Dahlia is the Anemone form. It has one or more rows of petals surrounding their tubular center.

There’s Ball Dahlias, they’re also mid-sized. And there’s Pom Pom forms that really are truly round in their flower form, whereas the Ball Dahlias have a flat face. There’s Waterlily forms, obviously that look like water lilies – with a beautiful flat bottom and a fully double top.

With all the sizes, colors and flower forms available, you can see why Dahlias are so popular. For more information on growing and the selection of varieties available, go to our website.
