Meet Your Forbidden Birth Month Flower – And The Secret Meanings Behind All 12
Every month has a flower with a darker story to tell – from poisonous beauties to ancient witch's herbs and blooms steeped in folklore.
Forget the classics; did you know you have a forbidden birth month flower?
Every year, without fail, I find myself looking up birth month flowers. I know perfectly well what mine is by now, but somehow I still end up reading every list I come across, nodding along as though I've uncovered a profound new truth about my personality. Then, before I know it, I'm halfway down another rabbit hole of birth month trees, birth month birds, birth month animals, birth month bugs – honestly, if someone can assign me a symbolic creature or plant based on the month I was born, I'm interested.
It's not just me, of course; we all like seeing ourselves reflected in nature. We like to believe there's a flower that captures our best qualities, a tree that shares our quiet strengths, or a bird that somehow understands us on a soul-deep level. Whether it's scientific or not hardly matters. It's comforting, it gives us another excuse to learn about the natural world, and it's fun... especially if you use it to lean into your dark side!
All 12 Forbidden Birth Month Flowers
That's right; lately I've found myself wondering about our shadow sides instead. Not the parts of ourselves we'd necessarily change, but the qualities that make us a little more mysterious, complicated, stubborn, passionate, or quietly rebellious. Every personality has one, right? So if every month has a traditional birth flower celebrating sweetness, hope, or friendship, surely there's a darker botanical counterpart waiting in the wings.
Enter stage left, then, the forbidden birth month flowers.
Some of these plants are poisonous. Some were prized by herbalists before becoming tangled up in folklore. Others have long been associated with witches, spirits, ancient myths, or whispered superstitions simply because they were unusual or misunderstood. Either way, I think we ca all agree that every last one of us deserves a flower with a little mystery...
January – Hellebore
If you were born in January, I can't imagine a better forbidden birth month flower than the hellebore.
While the rest of the garden is still asleep, hellebores are already flowering through frost and snow, earning nicknames like the Christmas Rose and Lenten Rose. They look impossibly delicate, but every part of the plant is poisonous if ingested. And, just like January babies everywhere, they survive difficult seasons not through noise or force, but through determination and staying power.
Go for something like the Frostkiss® Vibey Velvet™ Lenten Rose from Nature Hills if you want to grow your forbidden birth month flower at home!
February – Foxglove
Tall, elegant and almost impossibly beautiful, foxgloves have inspired fairy folklore for centuries. Legend claimed the tubular flowers were gloves for fairies or tiny lanterns lighting woodland paths.
The reality is rather darker; foxglove contains compounds that have transformed modern heart medicine, but the plant itself is highly toxic if eaten. So, what does that tell us about February babies? Why, that creativity is powerful – and so are you. Never underestimate imagination.
If you're going to do it, do it like Wham! would want and do it right. I love the Dalmatian Purple Foxglove from Walmart for its vivid purple blooms, if you're wondering.
March – Monkshood
March personalities are often thoughtful before they're outspoken, which makes sense, when you consider that their forbidden birth month flower is monkshood.
Its rich violet-blue flowers are among the prettiest in any perennial border, yet it's one of the most poisonous ornamental plants in the world. Also known as wolfsbane, it's been linked to myths involving witches, wolves and ancient hunters for centuries.
Buy yourself a pollinator-friendly monkshood from Walmart and watch your garden become a buzzing hotspot for bees and butterflies galore!
April – Bloodroot
I know, I know; at first glance, bloodroot looks wonderfully innocent, but don't let this forbidden birth month flower fool you.
The native beauty opens brilliant white blooms in early spring before disappearing back into the woodland. But snap the root, and a dramatic crimson sap appears almost instantly – the feature that inspired its unforgettable name and centuries of traditional use.
It hammers home the credo, then, of every April baby: never mistake gentleness for weakness. Pick up a pack of Bloodroot Native Wildflower Seeds from Everwilde, then, stat!
May – Lily Of The Valley
May is reliable, warm, and sociable – exactly the sort of personality people tend to underestimate. So, yes, naturally their forbidden birth month flower is much the same.
The tiny white bells of lily of the valley smell heavenly and look so beautifully innocent... but every part of the plant is highly poisonous.
There's a lesson in that, I guess; the kindest people are often stronger than anyone realizes. Bag yourself a Lily of the Valley Bare Roots Plant from CZ Grains, then, and channel that spectacular resilience in your own yard!
June – Belladonna
Few plants have a reputation quite like deadly nightshade. For centuries, belladonna was woven into stories of witches, cosmetics, medicine, and poison. Its glossy black berries and purple flowers have fascinated people for generations.
It makes sense, then, that it is the forbidden birth month flower for June. Because romantic, open-minded, and endlessly curious, June personalities are often drawn to mystery.
Belladonna reminds us that fascination and danger sometimes grow side by side – and that charm is a force all of its own. You can buy Belladonna Seeds from Walmart, but... be careful. Poisonous, remember?
July – Angel's Trumpet
Some flowers whisper, but angel's trumpet... well, the clue's in the name, folks! Those enormous trumpet-shaped blooms hang from the branches like chandeliers, releasing their sweet fragrance as dusk falls. And yes, every part of it is highly poisonous.
If any forbidden birth month flower belongs to July, I think it's this one. Bold, magnetic and impossible to ignore, it mirrors the warmth and confidence so often associated with midsummer personalities. Channel that and buy yourself an Angels Trumpet from Walmart, stat!
August – Oleander
If I had to crown one flower the survivor of the garden, it would be oleander.
It thrives where many plants give up, shrugging off relentless sunshine, poor soil and weeks of dry weather while continuing to flower as though nothing has happened. In warmer parts of the US, it's the shrub that keeps looking immaculate long after everything else has started to wilt... and that resilience? A trademark of August babes.
Its beauty comes with a warning, though. Oleander is one of the most toxic ornamental plants you can grow, a reminder that strength and softness can exist side by side. Pick up a Petite Red Oleander from Walmart, then, stat!
September – Autumn Crocus
There's something wonderfully confident about a flower that refuses to bloom until everyone else is packing up for the season, right?
Autumn crocus waits patiently while summer takes centre stage, only unfurling its elegant goblet-shaped flowers as the days begin to cool. It's a forbidden birth month flower which effortlessly proves that arriving late doesn't mean missing your moment – sometimes it's exactly what makes you unforgettable.
Beneath that graceful exterior lies a darker secret. The plant contains colchicine, making it one of the most poisonous flowering plants in cultivation. If you're willing to be careful, though, you can bag Saffron Crocus Corms from Amazon easily enough!
October – Castor Bean
If ever there were a forbidden birth month flower that proved beauty can be deceptive, it's castor bean. Gardeners grow it for its enormous burgundy leaves and striking scarlet seed pods, which give borders an almost tropical feel by late summer. Hidden inside those spectacular seed capsules, however, are some of the most toxic seeds found in any ornamental plant.
For analytical October personalities like yours truly, it feels like the perfect match. Thoughtful, composed and quietly unforgettable, it reminds us that appearances rarely tell the whole story. You can buy castor bean seeds at Walmart if you want to honor your floral shadow!
November – Crown Imperial
Few flowers command attention quite like crown imperial. Its fiery orange or golden bells hang beneath a spiky tuft of leaves, giving it a regal silhouette unlike anything else in the spring garden. For centuries, it's been surrounded by folklore, with one legend claiming the flowers bowed their heads in sorrow after witnessing Christ's arrest in the Garden of Gethsemane... and they've never looked skyward since.
Beneath all that grandeur lies a more mysterious side. The bulbs are poisonous if eaten, and the plant has a famously musky scent that many believe helps deter moles and rodents. Still, for determined November personalities, it feels like the perfect forbidden flower: proud, resilient and quietly unforgettable.
Try these Yellow Imperial Crown Flower Seeds from Amazon for a twist on the classic.
December – Moonflower
While most flowers close up as daylight fades, the moonflower is only just waking up.
As evening falls, this forbidden birth month flower's enormous white blooms slowly unfurl, glowing against the darkness and filling the air with fragrance before closing again with the morning sun. Catching one open almost feels like stumbling across a secret, and that fleeting beauty is exactly why I love it!
For optimistic, adventurous December personalities, moonflower is a reminder that some of life's most magical moments happen after everyone else has stopped looking. If you want your garden's brightest moments to happen after the sun has set, buy yourself some moonflower bush seeds from Walmart.
The more I researched these forbidden birth month flowers, the more I found myself wanting to grow them all. Traditional birth blooms celebrate the qualities we proudly wear on the surface. These celebrate something quieter – resilience, curiosity, independence, determination and the wonderfully complicated parts of ourselves that don't fit neatly into a greeting card.
Of course, many of these plants are genuinely toxic and should always be grown with care, especially around children and pets. But admired from a respectful distance? Why, then they remind us that the most captivating flowers are often the ones with the richest stories to tell.
And, sure, they add a little spookiness to the equation, too. What could be better?
