Plant Fact or Fiction: Part 3!

Charlotte Weidner | February 14, 2026

They've been a staple ingredient for horror for centuries - Man-eating plants, body snatchers and mind-controlling monsters, bloodsuckers, and creepy-crawly things that go bump in the night. Plants are the silent members of a league that includes Vampires, Frankenstein, and Werewolves. Strange plant myths have permeated nightmares, literature, television, and film. And why shouldn't they?

You’ve seen last year's installment of Spooky Plants, so here are some more creepy crawling plants to send shivers down your spine!

Parasitophobia is the Fear of Parasites!

Plant Parasites

Fiction is filled with tales of parasitic beings from other worlds like in the movie “Annihilation” (2018), but ours is FILLED with parasitic plants and creatures! Like the Rafflesia Corpse Flower above, these plants live in poor soils or are just adventitious and live off the hard-earned nutrients other plants make.

Strangler Fig seeds germinate on the branches of another, then the roots of the Strangler Fig gradually wrap around the trunk of its host. Over time, it eventually suffocates (strangles) the other tree and then takes its place as it uses the dead tree as scaffolding for itself to climb toward the sun.

Other parasitic plants include Strangleweed, or Strangle Tare ‘Grass’ (Cuscata), also known as Witches Hair.
The Christmas favorite, Mistletoe is actually a parasitic vine preying on their host tree.
If you are lucky to see a spooky white mushroom-looking plant called Ghost Plant/Indian Pipe while hiking in the forest, count yourself lucky! These are beautiful and rare plants to come across here in the US.

Mycophobia is the Fear of Mushrooms!

Creepy Mushrooms!

Some Mushrooms are just plain creepy sounding - Witches Black Butter, Wolf’s Blood, Jelly Babies, Trumpets of the Dead, Devils Cigar, Dead Man’s Fingers, and Starfish Fungus!

There are Jelly Ears that look exactly what they sound like, Little Brain or Brain Mushrooms have folds and are round like an old brain Igor left behind. The Dog Vomit Slime Mold definitely lives up to its name. Green Earth Tongues - yeah, they look just like they sound. Devil’s Fingers look like a ghostly hand coming out of the ground. Black Tree Monster with orange mouth-like openings. Puff Balls that look like alien spore-producing weapons. The Bride Veil is as eerie as it is beautiful and smelly, and the Common Pretty Mouth is anything but pretty!

The Bleeding Tooth Fungus (Hydnellum peckii) produces a red sticky substance from its pores and looks to be bleeding.

Deadman's Fingers Fungus have blackish-gray finger-like structures that resemble fingers coming out of the ground.

Stinkhorns are common fungi here in the US and form stinking slimy-looking tops to attract flies that spread their spores. There are even Octopus Stinkhorn that have long tentacles that are pink to red and can be as smelly as they are strange. The Stinky Squid which is an orange tentacled mushroom with the stench of death.

Cordyceps Fungi attack many types of insects and ‘zombify’ them! Even some species of snails and slugs can be infected! Entering through their exoskeletons and living inside their bodies until it's time to ‘bloom’ and release their spores. This is when the fungus hijacks the insect's brain and makes them climb to a high area for a bird to eat them and then poop out their spores!

Many types of Mushrooms have been discovered to be glow-in-the-dark! Called Fox Fire or Faerie Fire, they are filled with an enzyme called luciferase and they glow to attract insects to come spread their spores! Check out the new Firefly Petunia that has been mixed with glowing fungi to create a glow-in-the-dark flowering plant!

Lachanophobia is the Fear of Vegetables!

Talking Plants?

While we love to talk to our plants and it’s been found to be good for them, you’d be shocked if yours talked back to you! Well, plants can communicate without words! Like the movie “Avatar” where the blue aliens can communicate with plants and plants with everything else, plants really can communicate! While not like in Avatar or “The Happening” (2008), plants do communicate!

Sensing vibrations in the air without ears, knowing what's around them without eyes, feeling without nerves…the ways plants interact with the world around them go far beyond the funny sayings about ‘Potatoes having eyes’ and ‘corn having ears’!

Plants in the Tobacco family not only send each other chemical messages through their roots and through the air but also can call in for reinforcements when attacked!

Plant communication includes cries for help, invitations, and warnings in the form of odor molecules that our noses cannot detect. If a Tobacco plant is being eaten by a certain pest, it starts pumping out more nicotine. It then alerts other plants downwind to start producing more natural pesticides (that is what nicotine is really - natural plant pesticide), by way of airborne pheromones or signals through the roots the colony of plants share.

Still being attacked? Send out pheromones that attract that specific pest predator insect - usually a wasp - to come to the rescue! Researchers found that other plants in the area also pick up on these cues and gear up for battle as well!

Pollinated by Hawkmoths, Tobacco plants open their flowers at night. But when those Hawkmoths start laying eggs on their leaves (and start munching away) the plant switches to blooming during the day for hummingbirds instead!

Frequently Asked Questions

How much sun does my garden actually need, and can too much sunlight harm my plants?

Most garden plants thrive with 6 to 8 hours of direct sunlight daily, though this varies significantly by plant type, with full-sun plants needing at least 6 hours and shade-lovers performing best with 2 to 4 hours. Yes, too much intense sunlight can absolutely harm plants, causing leaf scorch, wilting, and bleached foliage, particularly in regions with hot afternoon sun like USDA Zones 8 through 11. Check each plant's specific light requirements before placing it, and in hotter climates consider positioning sun-sensitive plants where they receive morning sun but are shielded from the harsh afternoon rays between 2 and 5 p.m.

Should I add compost, fertilizer, or both when preparing my garden beds for planting?

Compost and fertilizer serve different purposes, so using both together gives your garden beds the best foundation. Compost improves soil structure, drainage, and microbial activity, while fertilizer delivers concentrated nutrients your plants need to establish and grow. Work 2 to 3 inches of compost into the top 6 to 8 inches of soil before planting, then apply a balanced slow-release fertilizer like a 10-10-10 according to package rates. Do this preparation a week or two before planting to give the soil time to settle and the nutrients to integrate.

Why are my plants wilting or yellowing even when I water them regularly?

Overwatering is actually one of the most common causes of wilting and yellowing, as waterlogged soil suffocates roots and prevents nutrient uptake, mimicking the same symptoms as underwatering. Check that your soil drains well and that containers have adequate drainage holes, since roots sitting in standing water will rot within days. Stick your finger 2 inches into the soil before watering, and only water when that depth feels dry. If root rot is suspected, unpot the plant, trim any black or mushy roots, and repot into fresh well-draining soil amended with perlite.

How do I protect my plants from pests and diseases without using chemical sprays?

Preventing pest and disease problems starts with choosing plants suited to your growing zone and placing them in the right light and soil conditions, since stressed plants are far more vulnerable to attack. Remove diseased foliage promptly, keep the garden free of debris where pests overwinter, and water at the base of plants to reduce fungal issues. Introduce beneficial insects like ladybugs and lacewings, and apply neem oil or insecticidal soap at the first sign of trouble for an effective organic option.

How much mulch should I put around my plants, and can I apply too much?

Apply mulch in a layer 2 to 4 inches deep around your plants, keeping it pulled back 2 to 3 inches from the base of stems and trunks to prevent rot and pest issues. Yes, you can absolutely apply too much, and volcano mulching, where mulch is piled high against a tree trunk, is one of the most common and damaging mistakes gardeners make. Excess mulch traps moisture against bark, invites disease, and can girdle roots over time. Refresh your mulch layer each spring, adding only enough to maintain that 2 to 4 inch depth rather than piling on a fresh layer without removing the old.

Can I grow shrubs, perennials, or fruiting plants successfully in containers long-term?

Yes, many shrubs, perennials, and fruiting plants thrive long-term in containers when given the right conditions. Choose containers at least 15 to 25 gallons for shrubs and fruiting trees, ensure excellent drainage, and use a high-quality potting mix refreshed every one to two years. In colder zones (below zone 6), move containers to an unheated garage or sheltered area over winter since roots in pots are more vulnerable to freezing than those in the ground. Select varieties rated one to two zones hardier than your local zone for the best long-term success, and fertilize regularly throughout the growing season since container plants exhaust nutrients quickly.

Which plants hold up best in hot, dry conditions with minimal watering or upkeep?

Drought-tolerant standouts include lavender, yarrow, sedum, and ornamental grasses like Blue Oat Grass, all of which thrive in USDA zones 4-9 with little supplemental water once established. Most of these plants need just one full growing season to develop deep root systems that carry them through dry spells. Avoid overwatering during establishment, typically watering deeply once or twice a week for the first 8-12 weeks, then scaling back significantly. Browse Nature Hills' drought-tolerant plant collections and filter by your hardiness zone to find the best fit for your region.

Should I prune or deadhead my plants during the growing season, and how does it help them?

Pruning and deadheading during the growing season encourages plants to put their energy into new growth and additional blooms rather than seed production. Deadheading spent flowers, ideally as soon as petals drop, is especially effective for repeat-blooming perennials and annuals throughout zones 3 through 9. Light pruning of woody shrubs can typically be done in early summer after the first flush of growth, but avoid heavy pruning after late July in most regions as this can stimulate tender new growth that won't harden off before frost. Make clean cuts just above a leaf node or lateral branch, and keep your pruning tools sterilized between plants to prevent the spread of disease.

Which plants grow better when planted near each other in a vegetable or flower garden?

This question falls outside the scope of the article provided, which focuses on parasitic plants, creepy fungi, and plant myths rather than companion planting. For companion planting guidance, Nature Hills Nursery recommends visiting naturehills.com where you can find resources on pairing plants like tomatoes with basil, roses with garlic, or the classic Three Sisters combination of corn, beans, and squash. Browse the site's plant pages for specific growing tips and compatibility information to help you plan your best garden yet.

How can I tell whether a popular gardening tip is backed by real plant science or just a myth?

Separating plant fact from fiction starts with checking recommendations against university extension service publications, which are based on peer-reviewed horticultural research specific to your region and USDA hardiness zone. Many popular gardening myths, like the idea that you should water plants on a strict daily schedule regardless of soil moisture, fall apart quickly when tested against basic plant science. A simple rule of thumb is to be skeptical of any tip that ignores variables like soil type, sun exposure, or climate. Cross-reference advice with sources like your local cooperative extension office or reputable nurseries before applying it in your garden.
