36 Black Plants – Creating a Goth Garden With Black Flowers

Halloween is coming soon and, since black is a color associated with this holiday, I thought it would be appropriate to do a post on black plants.

Adding these specimens to your roster of garden plants adds a dramatic look that will transform any outdoor space into a goth garden. Many of these plants can also be grown in planters which makes them ideal for Halloween decorating.

I have talked about Halloween plants in a previous post but, for today’s article, we will concentrate only on black plants and black flowering plants. 

The delightful contrast of these deeply colored plants, when combined with lighter plants is amazing. Keep reading to learn how you can achieve this goth garden look with black plants.

Are there actually black plants in nature?

True black flowers, like true blue blooms, are quite rare. Most flowers that are described as black are actually deep purple, deep brown, deep green, or deep maroon. 

Add to this the problem of watering and you will discover why black plants are hard to find in nature. Black plants require extra moisture, since their dark color attracts the sunlight and makes them more susceptible to withering and fading.

Soil pH also plays a part with these black plants since plant color often changes depending on the location of the plant or it’s soil pH.

The dark color of  black plants is caused by a pigment found in the plant’s cells called anthocyanin. Chlorophyll is the pigment which causes the normal green color. It absorbs all the colors from the light spectrum except green.

On the other hand anthocyanin absorbs only green and yellow, which makes the leaves look almost black.

Black perennial plants for a goth garden

If you are trying to create more of a goth look in your garden, try one of these  perennials. Whether they be black or almost black plants, they will add drama like no other color. 

Black mondo grass

Black mondo grass with berries.

Ophiopogon planiscapus ‘Nigrenscens’, also known as black mondo grass, heads the line up for a plant that is true black. The plant is perennial in zones 5-10. It is also evergreen, so it will keep its deep color all year long.

Be sure to plant black mondo grass in a sunny spot. It likes part sun in hot climates and full sunlight in cooler ones. Too much shade will fade the notable blackness of mondo grass.

Black mondo grass sends out berries in late fall. Ripe berries are also completely black or very dark purple.

Coral bells plum pudding

Many coral bells have deeply colored leaves but heuchera ‘plum pudding’ leaves are deeply plum colored which looks almost black.

The white and pink flowers appear in mid June on tall flower stalks. This plant is perfect for edging in a shade garden. It is also stunning in rock gardens.

Heuchera will grow indoors as a lower light houseplant. Select a spot that receives medium to bright indirect light, and water when the soil starts to dry out in the top couple of inches. 

Other black coral bells plants to grow:

  • Heuchera x villosa ‘Mocha’ – The leaves start out coppery colored in spring, and darken to charcoal black by summer. 
  • Heuchera black pearl – This is a stunning black foliage plant with jet black leaves and rosy purple undersides.
  • Heuchera Northern Exposure ‘Black‘ – Has clean lines with round black leaves and it keeps its color longer in the season than other heuchera plants.

Black lenten rose

Helleborus x hybridus ‘Blue Lady’ is a spring blooming perennial. Like all hellebores, ‘blue lady’ does well in a shady garden spot.

The flowers have muted shades in powdery blue to the deepest of purple black. Trim old leaves in late winter for maximum impact.

Most hellebores are cold hardy in zones 4-9.

Other helleborus plants with black or almost black flowers are these:

  • Helleborus niger – In this case, the name ‘niger‘, which means black, refers to the color of the roots not to black flowers or or black leaves.
  • Helleborus’Dark and Handsome’ – The plant bears flowers that are near black to black-purple and 2½-3″ in size.
  • Onyx Odyssey Hellebore – This variety features nodding deep purple cup-shaped flowers with pale green eyes at the ends of the stems. The flowers appear  from late winter to early spring.

Halfeti black rose

Many florists would like to convince us that black roses are common by using dye. However, true black roses do not exist, with one exception – the Halfeti black rose.

This true black rose exists in the village of Halfeti, in Southern Turkey. The reason that these roses are completely black is because the soil in the village has a high density and also contains the water soluble anthocyanins which react to soil pH.

Even in this village, the roses only turn black in the summer months. For the rest of the year, they are a very dark red color.

While we cannot enjoy this black rose in our gardens, there are some varieties have been bred so that the normal rose color is almost black. Some to look for are:

  • Rosa ‘Almost Black’ – I can’t think of a better name to describe this deep crimson red rose than to call it ”Almost Black”. 
  • Rosa ‘Black Baccara’ – The petals of this rose start out black but, as they unfurl, they turn to a rich burgundy red.
  • Rosa ‘Black Magic’ – This is the most popular red rose in the market today. The bud of this rose is very black but the mature rose is burgundy red.

Black Barlow columbine

Aquilegia vulgaris var stellata ‘Black Barlow’ is a perennial with double plum-purple, almost black, blooms which make great cut flowers.

Like most columbines, the plant is short-lived, but it will self-seed, so your garden will have it for a long time.

Fortunately for us, rabbit and deer don’t like this columbine, but hummingbirds and bees do!

Black Barlow columbine is cold hardy in zones 3-9.

Blacknight hollyhock

Alcea rosea ‘Blacknight’ produces deep black-purple single flowers on tall stalks in midsummer. The plant attracts hummingbirds and butterflies and is a popular choice for cottage gardens.
