Are you ready to add a touch of gothic elegance to your garden? Discover the allure of black flowers, from deep purple dahlias to mysterious bat plants. Whether you’re a seasoned gardener or just starting out, it’s time to embrace the dark side of floral design and create a garden that’s both beautiful and intriguing.

If you hyper-obsess about things (especially gardening) as I do, you may soon start looking for that near-black cosmos or rose you saw and plotting how to create a bit of the dark side in your own garden. Grab your cloak, a favorite autumn treat, and let’s take a walk down to the dark side–of flowers.

Demystifying Black Flowers

While Mother Nature hasn’t created any truly black flowers–at least that we’ve found so far–some blooms come close, in shades of deep purple and darkest reds. Breeders have been trying to bring these blooms closer and closer to true black; some are virtually indistinguishable from black.

Dark flowers are rare and often capture our attention because they’re different. A white rose is beautiful but not uncommon. Yellow flowers are a mainstay of our gardens. Our brain is satisfied that all is well when it registers green leaves and red, white, yellow, and pink flowers. The abnormal, the strange, and the dark catch the eye and make us pause. Perhaps it’s a throwback to days when our survival depended on noticing something out of the ordinary. Or, maybe there’s a twitch of the supernatural and mysterious.

The Language of Darkness: Black Flowers in the Garden

Deep, rich, dark colors symbolize mystery, intrigue, and the macabre. From fiction to real life, we associate black, dark red, dark purple, and charcoal gray with night and all its terrors. Vampires are not depicted wearing chartreuse cloaks, and traditional funeral and mourning attire is dark, somber hues, traditionally black.

 Deep, rich colors also signify elegance and sophistication–little black cocktail dresses or black-tie events. Many of us wouldn’t paint our bedrooms in black or blood red; it’s the wrong vibe. However, a little dark aesthetic and mystery in the garden can be just something that provides contrast or a fun design element. A sinister snapdragon? Perfect.

12 of Our Favorite Black Flowers

Here are a few black flowering plants to get your imagination going. When planning the garden, choose a few dark flowers with different bloom times. Black tulips won’t be around to create a dark and stormy night effect in September.

Black Hollyhocks

‘Blacknight’ hollyhocks are very cold hardy, making these blackish-wine-colored flower spikes accessible even for cold-weather gardeners. A taller plant, hollyhocks, can be used near a fence or as a pocket of height to create vertical and visual separation. Plant them near a turn in the path to hide what lies beyond. Learn all about growing hollyhocks.

Bat Flowers

Of course, nothing says spooky Halloween like bats, and the black bat flower (Tacca chantrieri) is unique. With two wing-like bracts above the purple blooms and a bat-like face (some imagination required), it’s not something your neighbor will have in their flower garden. Plant them in pots or in the shade.

Black Cosmos

We love cosmos for their seemingly endless bright blooms. They can also make great and economical space fillers, spreading out and providing summer-long color. The chocolate cosmos (Cosmos atrosanguineus) is a cousin of the regular cosmos we grow, with dark maroon blooms. It’s named for the chocolatey scent of the flowers. Several varieties are available, including ‘Black Magic’ and ‘Pinot Noir.’

With deep, purply-red (is that a word?) blooms, ‘Black Prince’ is a truly dark snapdragon. It’s a cut-and-come-again dark flower that will keep blooming into fall. It works well as a mid-height flower in beds or large urns. They are also one of our favorite flowers to grow from seed.

Dark Ornamental Grasses

Adding foreboding dark ornamental grass is where we look like garden design pros. ‘Blackhawks’ is a big bluestem cultivar. A native prairie grass, this new variety emerges dark green and then turns purple, which deepens as fall approaches. Use this tall grass to add a landscaped look and long-lasting dark color to your garden. It’s even deer-resistant.

Don’t forget the 2022 Perennial Plant Association’s Plant of the Year, a little bluestem (Schizachyrium scoparium) called ‘Blue Paradise.’ Its deep purple coloring and four-foot height make it great as a backdrop, bed anchor, or even the tall element in a large urn.

  • 4-5 feet tall
  • Full or partial sun
  • USDA zones 3-9
  • Peak color summer into autumn

Quick Tips on Creating a Gothic Garden

When creating a goth garden, whether in a couple of planters on the deck or an entire outdoor garden room, embrace the idea of moody and mysterious. Use “old” materials like iron, stone, and aged wood when possible. Even the mulch can be darker. Choose plants with varying heights and add wispy foliage that moves in the breeze. Plants with dark leaves are an eye-catcher all season.

Equally important–select for contrast. A garden with only one shade of foliage and flowers won’t pop; you’ll miss the details that make this aesthetic fun. Embrace the darkness not only with black flowers but also with startling complements–bright glowing whites make a splash of brilliance that only emphasizes the darkness around it. Go for hauntingly beautiful, not boringly drab.
