Cacti are some of the easiest and most rewarding plants to grow indoors. They require minimal care, add a touch of greenery to your space, and thrive in various home environments. If you’re looking for the perfect indoor cactus, here are 12 unique options that will bring style and personality to your home.
1. Bunny Ear Cactus (Opuntia microdasys)
The Bunny Ear Cactus is an adorable yet striking plant with flat, oval-shaped pads that resemble bunny ears. Its surface is covered with tiny, golden spines called glochids, which can be irritating to the skin, so handle it carefully.
This cactus prefers bright, indirect light but can tolerate some direct sun. Keep its soil dry between waterings, as overwatering is the main culprit behind its demise. Place it in a decorative pot, and it will become a charming focal point in any indoor setting.
2. Moon Cactus (Gymnocalycium mihanovichii)
Known for its vibrant, almost neon-colored top, the Moon Cactus is a hybrid grafted cactus that thrives indoors. The top part lacks chlorophyll, which is why it requires another cactus as a base to survive.
This small yet eye-catching plant prefers bright but indirect sunlight. Water it sparingly, allowing the soil to dry out completely before rewatering. Since it doesn’t grow too large, it’s perfect for small spaces, desks, or window sills.
3. Star Cactus (Astrophytum asterias)
A fascinating, low-maintenance cactus, the Star Cactus is known for its round, symmetrical shape and dotted patterns. It closely resembles a sand dollar and remains compact, making it ideal for indoor setups.
It thrives in bright but indirect light and needs well-draining soil. Water it only when the soil is completely dry. The Star Cactus also produces beautiful yellow flowers when happy, making it a stunning addition to any plant collection.
4. Old Lady Cactus (Mammillaria hahniana)
This charming, spherical cactus is covered in white, hair-like spines, giving it a soft, fuzzy appearance. It grows in clusters and can eventually produce pink or purple flowers in a crown-like formation on top.
Old Lady Cactus enjoys plenty of sunlight and well-draining soil. It’s best to water it sparingly, ensuring that the soil is completely dry before the next watering. Its unique texture makes it a perfect decorative piece for modern interiors.
5. Fairy Castle Cactus (Acanthocereus tetragonus)
Resembling a tiny fairytale fortress, the Fairy Castle Cactus has multiple upright stems that branch out over time. It’s an excellent choice for anyone who wants an architectural element in their indoor garden.
This slow-growing cactus prefers bright light and well-draining soil. Water it infrequently, only when the soil is dry. Over time, it will develop a bushy appearance, making it a fun and dynamic plant to own.
6. Ladyfinger Cactus (Mammillaria elongata)
A striking cactus with elongated, cylindrical stems covered in golden spines, the Ladyfinger Cactus adds a delicate yet dramatic touch to any space. It often grows in clusters and can even produce small pink or yellow flowers.
This cactus thrives in bright light and needs minimal watering. It’s perfect for decorative arrangements, terrariums, or even as a standalone piece on a windowsill.

Bishop’s Cap Cactus loves bright, indirect sunlight and requires infrequent watering. It’s a great low-maintenance plant that thrives with minimal attention.
8. Peanut Cactus (Echinopsis chamaecereus)
If you love trailing plants, the Peanut Cactus is a fantastic choice. Its slender, finger-like stems grow outward and eventually spill over the edges of its pot, creating a beautiful cascading effect.
This cactus enjoys bright light and occasional watering. It produces striking orange or red flowers when happy, making it an eye-catching addition to any indoor space.
9. Fishbone Cactus (Epiphyllum anguliger)
Unlike most cacti, the Fishbone Cactus has a tropical origin and thrives in humid environments. Its unique, zigzag-shaped stems give it a striking, artistic look.
It prefers indirect light and more frequent watering compared to traditional cacti. If you’re looking for a quirky plant with a different growth pattern, this is the one to get.
10. Golden Barrel Cactus (Echinocactus grusonii)
A classic among cacti enthusiasts, the Golden Barrel Cactus is a round, spiny plant that adds a bold aesthetic to any home. Its golden spines contrast beautifully with its green body, making it highly decorative.
It thrives in bright light and requires minimal watering. It grows slowly, but over time, it becomes a stunning focal point in any indoor setting.
11. Pincushion Cactus (Mammillaria spp.)
As the name suggests, this small, round cactus is covered in spines that give it the appearance of a pincushion. It often blooms with small, bright flowers in a circular pattern around its top.
The Pincushion Cactus loves bright light and should be watered sparingly. It’s an excellent beginner-friendly plant that requires minimal care while still looking beautiful.
12. Zigzag Cactus (Selenicereus anthonyanus)
A unique and rare find, the Zigzag Cactus is another jungle-type cactus with deeply lobed, jagged stems. It’s a fantastic plant for hanging baskets or elevated pots where its stems can trail downward.
Unlike desert cacti, it prefers indirect light and slightly more frequent watering. If you want something unusual and lively, this cactus will definitely stand out in your collection.
