These days, houseplants aren’t just greenery, they’re personalities. Scroll through Instagram or Pinterest and you’ll see the weirder the plant, the more love it gets.
From succulents that look like brains to trailing vines with polka dots, unusual houseplants add mystery, texture, and conversation to your space and they’re just plain fun.
If you’re ready to break out of the pothos-and-peace-lily routine, here are 15 unusual houseplants that are both beautiful and boldly strange, each one ready to turn your indoor space into a botanical showstopper.
1. Living Stones
- Botanical name: Lithops spp.
- Unique appearance: Pebble-like succulents that mimic stones
- USDA zones: 10-11
At first glance, you might walk right past Lithops thinking they’re just a handful of pebbles. That’s actually their survival strategy in the wild.
Native to the arid regions of southern Africa, these curious little succulents thrive on neglect and minimal water. They’re perfect for small pots, windowsills, or miniature plant arrangements.
Lithops are incredibly slow growers, and they usually flower in late summer or fall with daisy-like blooms that pop out of the slit between their fleshy leaves.
They require bright light and infrequent watering as too much water, and they’ll rot. Their dormancy period in summer can confuse beginners, but once you get their rhythm, they’re delightfully easy to keep.
2. String of Dolphins
- Botanical name: Senecio peregrinus
- Unique appearance: Leaves shaped like tiny jumping dolphins
- USDA zones: 10-11
This adorable succulent makes you do a double take. Each leaf genuinely resembles a miniature dolphin mid-jump. It’s a hybrid between string of pearls and candle plant, and it carries the whimsical charm of both.
String of Dolphins looks best in hanging baskets, where the vines can cascade dramatically. It enjoys bright, indirect light and dry soil.
Indoors, it can bloom with tiny white flowers that smell faintly like cinnamon, but the foliage is the main event. It’s a crowd-pleaser at plant swaps and a favorite on social media.
If you’re growing it in lower light, make sure to rotate the pot every few weeks to keep it growing evenly. Bonus, it’s pet-safe, so your curious cat can admire it without risk.
3. Polka Dot Begonia
- Botanical name: Begonia maculata
- Unique appearance: Olive-green leaves with white polka dots and red undersides
- USDA zones: 10-12
With its bold spots and dramatic red undersides, the polka dot begonia looks like a high-fashion plant straight out of a couture runway.
Native to Brazil, it prefers warm, humid environments and consistent moisture. It’s best placed near an east-facing window or under a grow light where it can get gentle light.
While it looks exotic, it’s not overly fussy. Pruning helps keep it bushy and full, and it rewards good care with clusters of pale pink or white flowers. Its striking looks have made it an Instagram darling, often seen in stylized home office corners or artful shelfies.
4. Buddha’s Temple
- Botanical name: Crassula pyramidalis x Crassula perfoliata var. falcata
- Unique appearance: Compact succulent with stacked leaves forming a temple shape
- USDA zones: 9-11
This sculptural succulent looks as if someone carefully folded and stacked tiny green origami squares into a living tower.
Buddha’s Temple is a hybrid variety that loves plenty of sun and dry conditions, making it perfect for bright indoor spots. It’s slow-growing and tends to stay compact, so it fits nicely in decorative planters or minimalist arrangements.
You should water it only when the soil is bone-dry, and don’t be surprised if it blooms with coral-red flowers in late winter or spring. Because of its slow pace and symmetry, many collectors use it as a focal point among more sprawling succulents.
5. Trachyandra
- Botanical name: Trachyandra tortilis
- Unique appearance: Spiral curly foliage resembling green ribbons
- USDA zones: 9-11
The surreal curly leaves spiral and twist of trachyandra like party streamers, making it one of the most eye-catching oddities in any succulent collection.
Native to South Africa, this rare gem is somewhat elusive to find and a little picky but totally worth it. It needs bright, indirect sunlight and well-draining sandy soil.
You should water it sparingly, allowing the soil to dry out completely between waterings as too much moisture can cause root rot. Its compact size makes it ideal for quirky desktop displays or creative succulent combos.
6. Bat Flower
- Botanical name: Tacca chantrieri
- Unique appearance: Black, bat-shaped blooms with trailing whiskers
- USDA zones: 10-11
Bat flower is gothic, dramatic, and utterly mesmerizing. Native to the jungles of Southeast Asia, this plant produces striking black or deep purple flowers with long, dangling whiskers that can grow up to a foot in length.
It prefers warm, humid environments and filtered light, much like its native understory habitat. So, you need to keep it in a well-draining mix with high organic matter and water consistently. Indoors, it loves bathrooms or greenhouses where humidity stays high.
This plant is a bit of a diva, but once you get the care right, it rewards you with blooms that feel like something out of a fantasy film.
7. Hoya ‘Hindu Rope’
- Botanical name: Hoya carnosa ‘Compacta’
- Unique appearance: Twisted, waxy leaves that look like a knotted rope
- USDA zones: 10-12
The hindu rope is a slow grower, but its thick, curled leaves and stunning porcelain-like blooms are well worth the wait. It’s an epiphyte, which means it grows in tree crevices in the wild, so it prefers good air circulation and doesn’t want to sit in soggy soil.
You want to let it dry between waterings, and make sure it’s in bright, indirect light for the best chance of flowering.
The flowers themselves are waxy and fragrant, appearing like clusters of tiny stars. I love trailing mine down a bookshelf where it turns into a natural sculpture over time.
8. Swiss Cheese Vine
- Botanical name: Monstera obliqua
- Unique appearance: Delicately perforated leaves with dramatic holes
- USDA zones: 10-12
Monstera obliqua is like the wild, fragile cousin of the ever-popular Monstera deliciosa. Its leaves are so thin and lacy, with more holes than leaf in some cases, that you might mistake it for being fake.
Native to Central and South American rainforests, it craves humidity, warmth, and indirect light. It’s more temperamental than other Monsteras and doesn’t grow quickly but when it does, it’s a showstopper.
Additionally, support it with a moss pole, and keep the soil lightly moist but never soggy. If you’re lucky, you might even get to see its small white flowers, but honestly, this plant’s foliage is its true masterpiece.
9. Frizzle Sizzle
- Botanical name: Albuca spiralis
- Unique appearance: Coiled, curly leaves that look like green springs
- USDA zones: 8-10
With leaves that look like they’re doing a little dance, Albuca spiralis is delightfully odd. Native to South Africa, it grows from bulbs and sends up tight curls that resemble miniature corkscrews.
The more light it gets, the curlier it becomes so you should place it in a bright spot. In late winter or spring, it produces yellow flowers that smell sweet, like vanilla.
However, note that this plant goes dormant in summer, and the leaves may die back. Don’t panic, you just reduce watering and let it rest until autumn.
10. Mistletoe Cactus
- Botanical name: Rhipsalis spp.
- Unique appearance: Long, spaghetti-like trailing stems
- USDA zones: 9-11
Unlike most cacti, Rhipsalis is native to rainforests and actually loves humidity. Its thin, cascading stems look like green noodles or tangled threads, and they make a mesmerizing curtain when grown in a hanging pot.
These plants thrive in indirect light and appreciate occasional misting. You might be surprised to know they produce small, white or pink berries but they’re not edible, but they do add a charming detail.
Specially, rhipsalis is great for beginners because it tolerates neglect and bounces back from a missed watering or two.
11. Resurrection Plant

You just keep it moist for a few days, then let it dry out again to mimic its natural cycle. It’s also fascinating for kids and adults alike.
12. Carrion Flower

Stapelia gigantea produces gigantic star-shaped blooms that look almost too perfect to be real, often with fuzzy red edges and leopard-like spots.
But the catch is that they smell like rotting meat to help with pollination. Despite the stench, the flowers are stunning and make an unforgettable impression.
It prefers warm, dry conditions and grows well in pots. You should water sparingly and provide plenty of light. Just don’t place it near your dinner table during blooming season!
13. Butterfly Pea Vine
- Botanical name: Clitoria ternatea
- Unique appearance: Deep blue, velvety blooms shaped like butterflies
- USDA zones: 9-11
This climbing vine might be more common in tropical climates, but with a little care, it thrives in containers too. Its vibrant indigo blooms are used in teas, food coloring, and even cocktails.
Native to Southeast Asia, butterfly pea loves full sun and warm temperatures. With regular pruning and support, it grows quickly and rewards you with a cascade of dramatic flowers.
Moreover, watching it climb and bloom feels like having a bit of a jungle on your patio. If you want a functional plant that’s also a stunner, this is your pick.
14. Sensitive Plant

- Unique appearance: Perfectly round, striped sphere resembling a baseball
- USDA zones: 10-11
If a plant could double as a tiny sculpture, this would be it. Euphorbia obesa is a chubby, perfectly rounded succulent that looks almost manmade.
Native to South Africa, it stores water in its stem and needs very little care. Just a sunny spot and occasional watering will keep it content.
Over time, it may grow taller and develop subtle ribs or ridges, giving it a fascinating texture. One note is that the sap is toxic, so it’s best to keep away from curious pets or kids.
Besides, its symmetrical shape and muted green striping make it ideal for modern spaces or minimalist plant shelves.
