Are you thinking of planting some black perennial flowers to make your garden look a little more unique? Finding the right balance of color for your garden can be quite challenging. That's why it's good to have many different flowers of different species planted to balance each other out. In this article, we examine our favorite black perennial flowers for your home or garden.

Black Perennials

Gardens are full of all sorts of beautiful colors, from sunny yellows to deep reds, corally oranges, to dazzling blues and bright yellows. There is one color that rarely appears in most of our gardens, and that color is black. Black flowers are becoming increasingly popular, adding drama to borders and producing strikingly stunning blooms year after year. 

While there are many different black flowers, you may decide that perennial black flowers are a better choice for your garden. Black perennials are an excellent choice if you want a black flower that comes back year after year.

So, whether you’re here because you are currently redesigning your garden, or you simply want to add a splash of black, you’ve come to the right place. Here in this guide, we will take you through some of our favorite black perennial flowers for your garden. Let’s take a look at what nature has to offer us. 

Why Choose Black Flowered Perennials?

Flowers with black petals have become more and more popular over the years for many reasons.

There are many reasons to choose black perennials for your garden, far too many to list. Black doesn’t always have to mean dark and dreary! Here are just some of the reasons why black flowers are becoming increasingly popular. 

  • They are mysterious and elegant 
  • Make brighter colored flowers pop 
  • They are rare and make a brilliant focal point 
  • They change color throughout the day depending on the light 

Perennial flowers are the friends that come back year after year. Some are tender perennials that need extra protection in the winter if you want to enjoy them for years to come. Others will last decades if you treat them with the love they deserve. Although perennials tend to offer shorter-lived blooms than annuals, they are easy to care for once established. Plus, the results are often outstanding.

Petunias are either annual or perennial bedding plants. Black Velvet Petunias are a relatively new hybrid that was developed in 2010. This bloom produces black velvet single flowers (hence the name) that sit on the bushy light green foliage. This plant is one of the deepest, true black flowers that you can find. Making it perfect for those wishing to add some beautiful darkness and drama to their garden. 

Petunias bloom in late spring through to autumn, and they need protection from frosts if you want them to return the following year. They need light, well-drained soil with plenty of sun. And shelter from winds and heavy rain as they are pretty delicate. They need deadheading regularly and are prime targets for slugs and other pests. This plant does best in zones 9 to 11. 

Black Bat Flower

Black Bat Flower
This flower is technically an orchid that grows best in warm, humid climates.

Scientific name: Tacca chantieri

This is a showstopping flower, so if you’re looking for something unique in your garden, this could be the flower you’ve been searching for. It is called the Black Bat Flower because it looks like a bat in flight, but it is also known as the Devil’s Flower or Cat’s Whiskers. This is a rare orchid that is deep purple to black in color, with long, hanging light-colored filaments. The Black Bat Flower has large attractive leaves that surround the bloom. 

This flower is described by many as hauntingly beautiful, and it blooms spring through to summer. The one downside to this flower is that it only grows outdoors in one zone, zone 11. It requires warm subtropical to tropical climates. In the right environment, it can also do well as part of an indoor garden. It is naturally found in the damp shadows in the tropical jungles of Asia, so it enjoys partial shade and light, well-drained soil.

These black perennial flowers for your garden range from delightfully delicate to spectacularly spooky. So be sure to choose wisely depending on what look you are going for in your garden. 

Our selection of flowers ranges from early to late bloomers, requiring different zones and care. Meaning that there is something here for every garden and gardener.
