It’s time to get your spook on – with black plants, creepy flowers, Halloween plants and all sorts of growing things that are sure to make you feel a Halloween mood.
Traditional Halloween decorating is done with just a few plants and colors. This time of the year is cold and plants in most areas of the country are starting to go dormant.
However, this doesn’t mean that our gardening hearts are being put to bed for the winter when we get the garden ready for fall. Most true gardeners think of plants all year long – and the holidays are no exception.

Looking for some creepy plants to grow for Halloween?
Plants that are perfect for Halloween are not your normal type of plants with pretty flowers or foliage.
These plants are dark and dreary with spikes, and fangs and all the somber colors of the season.
Creepiest plants associated with Halloween
In a traditional Halloween garden setting, pots of chrysanthemums and asters along with pumpkins are often used to set a festive mood.
Natural items are the most common things to use in any Halloween decor project.
While this is a great look for fall, pumpkins and mums are not the only Halloween plants available. Depending on where you live in our world, Mother Nature has a whole host of spooky plants that remind us of Halloween.
The color and common names of plants play a big part in deciding which are the spookiest plants for Halloween.
Black, purple and brown Halloween plants
One of the most often seen colors on Halloween night is black. It is the color of witches and black cats and bats. Trying to find a true black plant is a challenge, though.
Many plants that we think of as black are actually a very deep burgundy. Colors like purple and brown also play a part in Halloween mood setting. They are somber and eerie looking and can bring our minds to thoughts of death and destruction.

Black Magic elephant ear
The botanical name for this plant is Colocasia esculenta. This large and leafy plant is commonly known as “Black Magic Elephant Ears.” What a perfect name for a Halloween plant!
These plants are grown for their dramatic foliage that is reminiscent of the ears of an elephant. Elephant ears are a member of the arum family, to which the calla lily also belongs.
Elephant ear plants don’t like the cold. Mine stop growing when the night time temperature falls below 50° F but will return in the spring.
They will grow in pots, though. So if you have one growing on a patio, you could bring it indoors for Halloween.
Black mondo grass
This perennial isn’t actually a true grass, in spite of its name. Black mondo grass – Ophiopogon planiscapus ‘Nigrescens’ – is a member of the Poaceae family.
The plant looks similar to liriope, often called “monkey grass,” but is a different plant even though they grow in a similar way.
Black mondo grass is normally grown as a ground cover in semi shady locations, but can be grown in containers, which makes it the perfect plant for your next adult Halloween party!
Deadly Nightshade
Atropa belladonna has long been associated with death. It is rumored that the Roman empress Livia Drusilla used the juice of the plant to murder her husband, Emperor Augustus.
Deadly nightshade is the common name of this poisonous perennial plant in the Solanaceae family. Surprisingly, this family also includes tomatoes, potatoes and eggplants.
This plant is considered one of the most toxic plants in the Eastern Hemisphere. For this reason, you probably won’t want a container of it growing, but it is sure to be included in any list of Halloween plants.
Bat Head Lily
What could be more perfect for Halloween than this fabulous lily plant that looks like a bat? The first time I discovered bat head lily was on a trip to Biltmore Estate.
The conservatory at Biltmore is filled with unusual orchids, but none quite as spectacular as this exotic looking lily. The color is a deep brown, and there is no mistaking the bat-like face.
The creepy plant Tacca chantrieri has “wings” on the side that look like bat wings and very long whiskers that bring to mind a creature from an alien planet.
Fortunately, bat head lilies are perfectly happy in containers, so adding one to your Halloween party as a decoration is easy to do.
Dracula Orchid
Dracula and Halloween go together like a hand and a glove. Just as Dracula tempts unsuspecting victims towards him, Dracula Orchid tempts flies by trying to look like a mushroom.
The creepy flowers of Dracula orchids have a warty texture. This gives the viewer the impression that there are two small eyes in the flower, staring outward.
The colors are bright and bold. The specimen above is impressive. The center almost looks like it has a beak shaped nose.
This orchid likes cool temperatures and slightly dim light. Keep evenly moist and re-pot every few years. Other Halloween sounding names for this species of orchid are Dracula vampira, and Dracula chimaera.
Devil’s Claw Plant
With a common name like “devil’s claw plant,” you know this is a contender for classification as a spooky Halloween plant. The curved leaves of the plant are very sticky and covered with fine hairs.
The roots and tubers of the “devil’s claw plant” – Harpagophytum – are used to make medicine for all sorts of problems, including gout, arthritis and muscle pain.
The plant grows across the Sonoran desert in areas from Southern California and across to Texas, as well as South into Mexico.
Voodoo Lily
Some members of the Amorphophallus family are known as voodoo lily plants. These plants are grown for the huge size of their flowers and for their unusual foliage.
Like the corpse plant shown below, the flowers produce a strong, and offensive odor which reminds us of rotting meat. This smell attracts flies that will eventually pollinate the scary looking flowers.
Although voodoo lily has an exotic appearance that indicates it would be difficult to grow, this is actually not the case.
Orange, yellow and red plants Halloween plants
Since red is also the color of blood, red flowers also have their place in any Halloween decor. Orange and yellow flowers are also a great choice for spooky Halloween plants, since they coordinate with pumpkins so easily.
I use orange all the time at Halloween, even in my drinks and cocktails. See my Halloween Witches Brew cocktail with gummy worm garnish for an example.
Some of these spooky plants are available at garden centers and others might require a trip into the jungle!
Candy Corn Plant
A favorite candy around Halloween time is candy corn. That makes a good candidate as one of the flowers associated with Halloween.
Did you know there are several candy corn plants with the typical orange, white and yellow coloring? Find out more about candy corn plants here.
Chinese Lanterns
The pods of the Chinese Lantern plant start out green but by the end of their growing season in early fall, the color turns to orange. This plant is Mother Nature’s way of giving us a natural Jack-O-Lantern.
Their rustic color makes them the perfect choice for fall decorations. The plant likes full sun and is hardy in zones 3 to 9.
One note: Like many other plants on this list, Chinese lantern plants are considered poisonous. Even though they are often seen this time of the year, don’t decorate with them if you have young children or pets in the house who might be tempted to eat them.
Corpse Flower
It is not the look of corpse flower – amorphophallus titanum – that will scare you, but the smell surely might. Not to worry, in cultivation, this plant only flowers once in 7-10 years so you won’t have the smell around very often.
While the plant is blooming, the flower has a strong odor similar to rotting meat, thus the common name “corpse flower.”
The reason for the smell is that dung beetles, flies and other insects are attracted to this smell and they are the primary pollinators of the flowers.
Corpse flower is called one of the world’s largest flowers. Its bloom can grow to more than eight feet in height and four feet across.
It is a rare tropical plant that is native to the rain forests of Indonesia.
Witch Hazel
It is not often that plants flower around Halloween time, but witch hazel is an exception. Hamamelis virginiana, has a common name “witch hazel.”
It is a fall-blooming, deciduous tree that is native to The Appalachian Mountain area of Eastern North America.
Legend has it that the wood of the tree has special powers to detect underground salt and water, as well as precious metals.
These qualities give Witch Hazel an eerie quality, that makes it a spooky plant to observe around Halloween.
Bleeding heart
Blood is often associated with Halloween, so a plant with the name bleeding heart seems to be a contender in our search for Halloween plants.
The flowers of Dicentra Spectabilis – commonly known as bleeding heart, are even shaped like hearts. Extending from the end of the bloom is a tear drop shaped petal which gives the plant its spooky Halloween name.
Normally, bleeding heart blooms in spring, so it is unlikely to find one blooming in autumn unless you live in a very tropical zone. If you can find it, the plant would be perfect to add to any Halloween display.
Find out more about growing bleeding heart here.
Dragon’s Blood Sedum
The deep red flower buds of “Dragon’s Blood Sedum” are the color of blood, which has long been associated with Halloween. The leaves turn red when the cool temperatures of fall arrive. The botanical name of the plant is sedum spurium. 
The plant is used as a ground cover and is also popular in rock gardens. Fortunately, this sedum is winter hardy in zones 3-9, so it can take those cool fall temperatures in stride.
This makes it an ideal plant for your Halloween decorations.
Spider lily
Lycoris radiata has dozens of long and curling stamens which give this lily its common name “spider lily.” What could be more Halloween inspired than spiders?
The plant is common in areas of Asia. In Japan, the red spider lily signals the arrival of fall. Many Buddhists will plant spider lilies on graves as a tribute to the dead.
Legends show this flower as having a connection to the dead. Japanese translations of the Lotus Sutra depict spider lilies as ominous flowers that grow in Hell, and guide the dead into the next reincarnation.

Halloween has long been paired with ghosts and mummies, both as outdoor decorations and in Halloween costumes. 
The color white also has a smokey and eerie feel that sets a mood beautifully. Here are a few white Halloween plants to bring on that spooky feeling.
Ghost Plant
Monotropa uniflora is also known as ghost plant, Indian pipe or corpse plant because of its eerie and ghostly look. It is a perennial plant that is native to temperate areas of Asia, North America and South America.
The plant is unusual in look but is found in quite a wide area of the USA, from Maine to California and from Florida to Alaska.
You won’t find it in the Southwest, Mountainous West or Central Rocky Mountains, though.
One unusual aspect of this plant is that it has no chlorophyll and does not depend on photosynthesis to grow. That means that this ghostly plant is able to grown in the darkest of forests.
Old Man Cactus
Nature is amazing. To decorate for Halloween, one has only to look to a plant called “old man cactus.” This fun variety of spiky cactus has the botanical name cephalocereus senilis.
The plant has fluffy tufts of hair which sit over a surface of spikes on a tall cactus body.
The look is reminiscent of an old man, thus the common name. To use this plant to decorate, I like to add a pair of wiggle eyes and my Halloween decorating is done!
This interesting cactus is not just a plant for Halloween. It is an easy care addition to any cactus garden. Get my growing tips for old man cactus here.
Ghost plant succulent
In spite of the common name – “ghost plant,” Graptopetalum paraguayense doesn’t have a scary look.
It is a hardy succulent with pale gray or white colored leaves. It is native to Mexico and is often used as a ground cover.
Ghost plant succulent is quite drought-tolerant. If your plant begins losing an some leaves, don’t worry. Hold back on the watering a bit and use those extra leaves to grow new succulents.
Succulents are easy to grow and popular with those new to gardening. Care of succulents depends on the variety but most need bright sunlight and don’t like to be over-watered. Find out more about growing succulents here.
Doll’s Eye Plant
The berries of Actaea pachypoda, commonly known as “doll’s eye plant,” are stark white with a single black dot on a bright red stem. The entire plant is toxic to humans and can even cause hallucinations.
Even a small contact with skin can cause blisters.
For this reason, it’s not likely that you would use doll’s eye to decorate for a Halloween party, but it still belongs in our list of spooky Halloween plants.
Spooky green Halloween plants
With all the colorful scary plants to choose from, green plants might be considered boring at Halloween time, but look again. These spooky plants will set a Hallowoeen mood simply because of their names.
If you add them to your Halloween decor, be sure to add a name tag to the pot to show your guests why you chose this particular plant for a Halloween decoration!
Venus Flytrap
Remember the classic thriller Little Shop of Horrors? In the musical, a florist raised a plant, named Audrey II, that fed on human blood and flesh.
Readers often ask me “what is the Little Shop of Horrors plant name? There is no actual plant exactly like the one in the movie.
The movie version featured a creature that was a crossbreed of a butterwort and Venus flytrap which was named Audrey Junior. This creature was intent on taking over the world.
Because of this movie and musical history, it is no wonder that Venus flytrap made it to my list of evil looking plants. The look is enough to scare you silly!
If you live on the East Coast of the United States in North and South Carolina, you may have seen this plant. It is native to the wetlands of this area.
The “Venus flytrap” (Dionaea muscipula) is a carnivorous plant that catches insects and spiders with a trapping structure formed no the ends of the plant’s leaves.
The traps are triggered by tiny hairs, and snaps shut on its prey. The Venus flytrap plant is listed as as a vulnerable species by the National Wildlife Federation.
Brain cactus
Skulls have long been associated with Halloween. Brain cactus is a unique type of cactus that not only has the spooky name but also the unusual shape of the brain itself!
The “brain cactus,” Mammillaria Elongata ‘Cristata’, is native to central Mexico. It’s an unusual form of the Mammillaria cactus that has a worm like crested shape that resembles a human brain, which is how it got its common name.
Some think that the cactus looks like worms, which are also associated with Halloween.
The shape of brain cactus occurs because of damage to the plant when it is young. Cells of the plant multiply at a faster rate than normal at the place of the damage.
This causes the twisted nature of the cactus that makes it resemble a human brain.
Brain cactus is a common house plant that is easy to find and easy to grow. It makes the perfect addition to any Halloween decor.
Spider plant
Chlorophytum is a tropical variegated plant that sends out long stems which have smaller versions of the mother plant at the end. The common name for this plant is “spider plant.”
The babies are easy to remove and grow as new plants. Because of their ease of propagation, you can have dozens of the spiders mixed in with your Halloween decorations.
Sensitive plant
The last spooky Halloween plant to make it to my list was chosen because it actually reacts when you touch it. Sensitive plants belong to a group of plants that are nyctinastic – they close up at night.
When you touch a sensitive plant, the leaf reacts by closing up slightly. After about 10 minutes, the leaves will open up again.
Mimosa pudica is the botanical name for this spooky Halloween plant that is hard to resist testing! Find out more about nyctinastic plants here.
Not only are these 21 Halloween plants scary looking, they have spooky names and back up the names with eerie looking flowers, leaves and berries. These creepy plants all scream that Halloween is here!
