Black Dahlias have an almost haunting beauty that makes them a favorite of gardeners and flower aficionados around the world. But, before you dive in, it’s important to do your homework. All Dahlias are not created equal. Just like any flower, some varieties will do well under certain conditions while others will die. You should know if the plant needs full sunlight or can it survive in partial shade? Some Black Dahlias need more water than others. It’s also crucial that you have the right type of soil to ensure a healthy plant.
We have assembled the information you need to choose the right Black Dahlia. Each one comes with its own set of advantages and requirements. Knowing a few important facts will give you the best chance to enjoy these unique plants in all their glory.
Black Jack Dahlias
Black Jack Dahlias have a striking appearance due to the size of the flowers and its curving, pointed petals. A semi-cactus, the Black Jack does best in sandy loam, yet, they can succeed in most garden beds provided they are well-drained and the soil is slightly acidic. You’ll also need to make sure they get lots of sunlight. Even if you live in colder zones, the tubers should survive in the ground over the winter.
Black Wizard Dahlias
Another semi-cactus variety, the Black Wizard Dahlia doesn’t need much care yet can deliver magnificent results.

Plant this one in the summer and you can enjoy its hypnotic beauty throughout the fall. You’ll need to add plenty of compost to the soil and keep the plant well watered.
The Fidalgo Blacky is an aptly named Dahlia that appears to be almost totally black. Yet, a closer look reveals that the bloom is actually a dark red that is truly arresting. This is an ideal cutting flower that can be grown as an annual. Plant in mildly acidic to neutral soil. And don’t overdo the watering. You won’t have any trouble seeing the Fidalgo Blacky in garden or border, as it grows up to four feet tall.
Lights Out Dahlias
Another gorgeous reddish-black variety with broad, velvety petals is the Lights Out Dahlia. If you live in a rural area these can be a good choice as they are deer resistant.
