Unusual and Unique Flowers You'll Fall in Love With

Roses and tulips represent a fraction of nature's flowering species. Thousands more exist — varieties that smell like chocolate, mimic animals, and glow in moonlight. Some thrive in UK borders, others need specialist care, but each offers something extraordinary.

Discovering these unusual flowers reshapes your approach to gardens, greenhouses, and gift-giving entirely. Their remarkable beauty deserves recognition beyond specialist collections where they currently hide.


Floral favourites

Peonies unfurl like tissue paper balls, gerberas bring primary colours to any room, and alstroemeria offer miniature lily clusters in every shade. Carnations add texture with their ruffled edges — each brings something different to arrangements.

Nature's creativity extends far beyond these familiar blooms. Some flowers smell like rotting meat to attract pollinators, others trap insects for days, and several even glow after dark.

Black bat flowers hang like Gothic decorations

Tacca chantrieri earned its common name honestly — these blooms look like Halloween decorations come alive.

Purple-black petals spread like wings above whiskers up to 25 centimetres long that twitch in any breeze. Malaysian rainforests harbour something far stranger than the name 'bat flower' suggests.

You can grow them at home, although they need 18°C minimum temperatures year-round, plus high humidity mimicking jungle conditions.

Chocolate cosmos smells like a dessert

Vanillin creates the chocolate scent in these burgundy flowers, and it’s identical to actual cocoa. On hot July afternoons, you'll think someone's baking brownies next door.

Botanists believed this species extinct until Mexican researchers discovered thriving populations in pine-oak forests. Now you can buy them at reputable garden centres, and they flower right through to October.

Parrot tulips emerged from accidents

Seventeenth-century French growers noticed twisted petals on otherwise standard tulips. Rather than discarding these mutations, they bred increasingly ruffled varieties. Modern cultivars feature petals slashed, fringed and curled beyond recognition as typical tulips.

'Black Parrot' produces flowers so dark they photograph poorly without good lighting, and 'Flaming Parrot' varieties combine yellow streaks with red in patterns unique to each bloom.

Passion flowers confuse pollinators

Passiflora incarnata's complex structure guides bee movement during pollination. Corona filaments radiate from centres like firework explosions frozen mid-burst. Early missionaries saw religious symbolism in the flower parts — five stamens, ten petals, thorny corona.

UK gardens support several hardy species that survive -15°C if roots stay dry. P. caerulea produces orange fruits after hot summers, though they taste disappointing.

Birds of paradise emerged from isolation

Strelitzia reginae evolved in South Africa, pollinated by sunbirds perching on blue arrow petals. Orange crests burst from boat-shaped bracts in sequence, each flower lasting approximately two weeks.

British conservatories suit them perfectly — they like their roots to be undisturbed and flower prolifically once established.

Corpse flowers time their stench

Kew Gardens posts countdown timers when their Amorphophallus titanum shows signs of blooming. Crowds queue for hours to smell rotting flesh — the spadix heats up to 37°C, broadcasting stench to summon carrion beetles.

A. konjac stinks just as badly but fits in conservatories. Japanese cooks turn the corms into konnyaku jelly, proof that awful-smelling plants can produce decent food.

Sea holly evolved on beaches

Eryngium's metallic blue bracts look nothing like normal flowers, more like alien props from a sci-fi film. Spiny leaves keep sheep away on clifftops where these plants grow wild.

E. x zabelii "Big Blue" turns electric against orange crocosmia or rudbeckia. Cut stems stay blue for years after drying, unlike most flowers that fade to brown within weeks.

Monkey orchids evolved deception

Dracula simia tricks fungus gnats into attempting to mate with flowers, mimicking female insects. Ecuadorian cloud forests hide these orchids 2,000 metres above sea level. Orange scent emerges only from mature blooms, distinguishing them from scentless hybrids.

Flowers display faces appearing more simian in person than photographs suggest. Cool greenhouse cultivation is possible, but summer temperatures above 29°C can prove fatal.

Jade vines glow in darkness

Strongylodon macrobotrys creates its unique turquoise luminescence via an unusual combination of common pigments under alkaline conditions.

Filipino bats pollinate three-metre flower chains, navigating by blue-green glow on moonless nights. Kew Gardens’ specimen flowers sporadically despite careful climate control and hand pollination attempts.

Seeds germinate readily, but vines need ten years' growth before flowering. Support structures must bear considerable weight — mature plants develop woody trunks like trees.

Finding botanical oddities

Specialist nurseries guard rare plant sources carefully, sharing supplier details reluctantly with newcomers. RHS plant fairs offer better hunting grounds than garden centres stocking predictable ranges.

Seed exchanges connect collectors worldwide — unusual varieties circulate among enthusiasts rather than reaching commercial markets.

Social media groups document flowering times obsessively, alerting members when rarities bloom nearby. Botanical gardens sell divisions during members' events, prices reflecting propagation difficulty accurately.

Strange flowers demand careful staging

Architectural blooms need breathing space. Cramming multiple specimens together diminishes impact, so give each flower room to display correctly.

If you’re creating a display for a show, then black backgrounds showcase pale oddities like queen of the night or ghost orchids.

Deep jewel tones, navy blue, and off-white backgrounds suit metallic sea holly or blue passion flowers better than pastels.

Growing unique flowers requires patience

Unusual plants rarely perform immediately. For instance, years can pass before your Strelitzia flowers, and decades for some orchid species.

Monitor those tiny changes, celebrate new leaves, and document progress photographically over seasons. Each small development matters when flowers take years to appear.

Conversations change around unusual flowers

Unusual flowers make memorable gifts — monkey orchids that look like tiny faces and corpse flowers famous for their stench. Not everyone can source these rarities, though.

Consider mixing everyday flowers for memorable arrangements. Peonies paired with alstroemeria create textural contrasts, and freesia adds fragrance to gerbera displays.

Yellow sunflowers with purple carnations deliver unexpected colour combinations that catch attention without requiring specialist suppliers.
