16 (Almost) Black Flowers for Your Garden

When we think of gardens, we often picture vibrant, colorful blooms that brighten up the space. However, something is intriguing and mysterious about the idea of growing black flowers.

Black can have an ominous tone, but black flowers symbolize farewell, rejuvenation, or rebirth. Plant these rare flowers to add intrigue to your garden.

You can also search by your growing zone by entering your zip code to ensure your chosen black beauty will grow well in your garden.  Also, be sure to check sun needs.

I hope you enjoy these dark, mysterious, yet intriguing blooms!

Note: While these flowers are commonly called black, their petals can range from very deep purples to dark burgundy or maroon. The term “black” is often used to describe their intense, dark coloration.

Are there any natural black flowers?

No. But some come close!

Are black flowers difficult to grow?

No, not necessarily. The same growing conditions required for other species will also be appropriate for most black blooms. However, some may require more maintenance than traditional varieties since they must be protected from direct sunlight (partial sun is fine) and waterlogging to preserve their dark hue.

Are black flowers rare?

Black flowers are not common in the plant kingdom. Most flowers come in various colors, but true black pigmentation is rare. This is because the pigments of most flowers produce colors like red, yellow, blue, or white – not black.

The dark color that flowers usually have is caused by the accumulation of dark pigments, such as anthocyanins or melanins, which makes them appear black or almost black.

Flowers labeled as black can often appear to be very dark purple or deep burgundy instead of true black. The perception of blackness in flowers can also be affected by temperature, lighting conditions, and individual perception.

Quick Flower Tips

  • Buy Flowers from a Trusted Source: The quality of the plant will be better if you buy from a trusted source. Check to make sure you are getting the best quality.
  • Feed Your Flowers: Most flowers love to be fed with flower or bloom food. This helps them stay healthy and look vibrant. They also love to be planted and fed with compost, worm compost, or chicken manure.
  • Be Gentle with Your Flowers: Flowers are delicate and can easily be damaged if handled too roughly. Handle them gently and avoid jostling them when picking, deadheading, pruning, and arranging.
  • Location Matters: Don’t try to grow a plant suited for a sunny location in the shade. It’ll struggle to thrive.
  • Watch Out for Pests: It’s important to watch out for pests such as aphids and scale, which can damage flowers. If you notice any, treat them immediately.
  • Deadheading: To encourage more flowers, deadhead the spent blooms. This will allow the plant to focus its energy on producing more flowers.
  • Properly Store Bulbs: Cold-sensitive bulbs should be stored in a cool and dry place.
