Black flowers have a very unique appearance, but it may surprise you to know that it’s impossible for a plant to be completely black. Instead, what you see as a black flower is usually a very deep shade of blue or purple. Because they’re so rare, having a darker colored flower in your garden or arrangement can add a touch of elegance, mystery, and power to them.
The sunlight requirements differ from black flower to black flower, but most look the best when you plant them in full sun. Not only will they thrive in this environment, but the sunlight can highlight the flowers’ darkness and depth. So, if you’re trying to add some dimension to your garden, we’ve outlined 21 great black flowers below.
1. Black Bat Flower
This black flower gets the name from the unique looks that resemble a bat in flight. This is a very rare plant that has a deep black-purple ruffled flower with hanging, long filaments. Adding to the uniqueness, the seed pods look like smaller bat faces. The dark coloring is further offset by bright green, large leaves.
This is actually an orchid, and it’s a very finicky plant that needs a lot of attention and close care. They are best planted in zones 9 to 11, and they prefer to grow in moist, warm, tropical climates. It doesn’t tolerate cold climates well, and it will die if the temperature drops below 55 degrees Fahrenheit. Unlike a lot of black flowers, it likes dappled shade instead of full sun. Even though this exotic flower requires more work, it’s well worth the dark, moody display the flowers put on.
2. Calla Lily ‘Black Star’
Calla lilies give you pretty trumpet-like flowers that will stand out in your garden or landscape design. This black flower will create a slightly darker mood than other cultivars or varieties, and the blooms are a very deep, burgundy-black color that grows on stems that are dark enough to match. The tubular flowers contrast sharply with the green, speckled foliage.
It will add a little welcome drama to your landscape, and the sleek look of the blooms adds modern elegance. It looks fantastic when you plant it in clumps alongside other brighter blooms or you can plant it by itself. It does well planted in container gardens or flower beds, and it’ll bloom during the late spring and summer months when planted in zones 9 to 11.
3. Columbine ‘Black Barlow’
This stunning black flower has been bred specifically for use in cut flower production, and it works well in cut flower gardens. This is the first cultivar of the Barlow series, and it offers spurless, double flowers. The blooms are a very deep plum color that is almost black, and they look like pom poms with spiky petals. The flower sits on a very long stem and towers over the greenish-gray, bushy foliage. They usually grow in clumps to create a dark spectacle that works well in a cottage garden border.
The columbine flowers bloom in the late spring or early summer months each year, but they are generally very short-lived. It has a self-seeding nature that allows them to grow very quickly under the right conditions. This plant is easy to maintain, and it thrives in a range of conditions in zones three to nine.
4. Cranesbill Geranium ‘Black Widow’
This geranium type has many names, including Dusky cranesbill, Mourning Widow, and Black Widow. These dark names come from the black flowers this perennial produces. The black flowers range from deep purple to dark maroon, and most of them look almost black. Even though the flowers are slightly smaller, they make a dramatic statement. The petals are concave or fold flat, and this allows the intricate centers of the flowers on display.
Blooms on this geranium rise above star-shaped or crinkled low-lying foliage. It loves shaded, dry areas, and this makes it perfect for woodland gardens. It does best in zones four to eight, and it’s a low-maintenance choice. It’s deer and rabbit-resistant, and it can spread rapidly under the right conditions, but it’s not invasive.
5. Dahlia ‘Karma Choc’
Karma Choc Dahlias are considered to be the darkest color you can get. They look like black flowers, but they’re actually a mass of velvety, dark red petals that fade to a very dark center, creating a pretty ombre effect. The flowers sit high above the plant’s foliage, and the foliage is a blue-tinted, dark burgundy color.
As the name suggests, this plant is part of the Karma collection, and it was bred specifically to have cut flowers that last a long time. The blooms have a vase life of roughly two weeks, so they fit nicely in cut flower gardens. Even though it’s bred for vase life, this plant looks wonderful in the garden.

Black Baccara is actually a hybrid tea rose, and it has dark, deep maroon petals that make it look like a black flower.

The Blackout viola is not only popular for their looks, but also for their sweet scent and how easy they are to grow. They flourish in a range of conditions in zones 6 to 10. They can grow in a full sun location, but they like partial shade in hotter areas. They’re vulnerable to damage from frost, and they will need protection in the winter. This elegant bloom works well as a ground cover, but you can also add them to rock gardens.
21. Western Coneflower ‘Green Wizard’
Coneflowers are pretty plants, and they add unique shapes and textures to your flower beds because they have flaring petals and exposed middle areas. The Western Coneflower is one of the three genera that exist for coneflowers, and it offers black flowers.
