Cactus Names India – Types, Botanical Names, Hindi Names & ID Guide
Buying a cactus in India without knowing its name is a common experience. The label says “Cactus” — nothing more. The nursery owner calls it “haathi cactus” or “chota cactus” or simply gestures at the group of pots and names a price. Online, the same plant appears under four different names across four different sellers, three of which are incorrect.
This is not a niche collector’s frustration — it is the everyday reality of the Indian cactus market. And it matters practically: a plant’s name determines the care it needs, the soil mix that suits it, the watering schedule that keeps it healthy, and the realistic expectation of how large it will grow.
After twelve years of identifying, sourcing, and growing cactus across India — and learning through hard experience which common names in the Indian market are accurate and which are creative fiction — this guide provides the naming reference every Indian cactus buyer needs: botanical names, common English names, Hindi and regional names, what is actually available in Indian nurseries, and how to identify an unlabelled plant from an Indian shop.
Understanding Cactus Names – The Three Name Types
Every cactus has potentially three types of names, and understanding the difference helps you search, buy, and care correctly.
Botanical (scientific) names
The internationally standardised Latin names that identify a cactus species precisely. Written in italics: Echinocactus grusonii, Mammillaria zeilmanniana, Opuntia ficus-indica. These names are consistent across every country, every language, and every nursery in the world — a Cereus peruvianus sold in Mumbai is the same plant as one sold in São Paulo or Amsterdam.
Botanical names have two parts: the genus (first word, capitalised — Mammillaria) and the species (second word, lowercase — zeilmanniana). Together they identify one specific plant within the estimated 1,800 accepted cactus species.
Why botanical names matter for Indian buyers: When you search for care information online using a common name like “barrel cactus,” you get mixed results covering multiple unrelated species with different needs. Searching Echinocactus grusonii returns precise, species-specific care guidance every time.
Common English names
Descriptive names that give a visual impression of the plant but are applied inconsistently. “Bunny Ears” refers to Opuntia microdasys in most contexts — but Indian nurseries sometimes use it for other pad-type Opuntia. “Golden Cactus” appears on labels for at least five different yellow-spined species. “Old Man Cactus” applies to both Cephalocereus senilis and Espostoa melanostele depending on who is selling.
Common names are useful for general communication but unreliable for care guidance and purchasing precision.
Hindi and Indian regional names
Cactus arrived in India primarily through colonial trade routes and do not have ancient Sanskrit or regional-language names the way indigenous Indian plants do. The names that exist are:
- Cactus / Kaktus (कैक्टस): The most widely used term across India — a direct transliteration of the English/Latin word used in Hindi, Marathi, Bengali, Telugu, Tamil, and most Indian languages
- Nagphani (नागफनी): The most common Hindi name specifically for Opuntia — the pad cactus. Nag = cobra, phani = hood — a reference to the flat, hood-like pad shape. Also spelt Nagphan in some regions
- Thoar (थोहर) / Thor: Used in Rajasthan and Gujarat for Euphorbia plants that resemble cactus — a common and important naming confusion (see below)
- Sehund (सेहुंड): Sanskrit name primarily for Euphorbia neriifolia — the Indian spurge commonly mistaken for cactus
- Kumari ka dost (कुमारी का दोस्त): Occasionally used for Aloe vera’s cactus relatives in Ayurvedic contexts — not a precise cactus name
- Haathi cactus (हाथी कैक्टस): Colloquial term used by some Indian nurseries for large, prominent cactus specimens — not a botanical designation
The India-Specific Mislabelling Problem
This section is unique to the Indian market and absent from every Western guide. Understanding these mislabelling patterns protects against wasted money, wrong care, and the frustration of watching a plant decline because it was misidentified at purchase.
Euphorbias sold as cactus
The most widespread and important mislabelling in India. Several Euphorbia species — Euphorbia trigona (African Milk Tree), Euphorbia lactea (Candelabra Cactus), Euphorbia neriifolia (Indian Spurge), and Euphorbia tirucalli (Pencil Cactus) — are routinely sold as “cactus” in Indian nurseries and online markets.
They are not cactus. They are succulents from a completely unrelated plant family (Euphorbiaceae) that have evolved similar spiny, water-storing forms through convergent evolution. The care difference is critical: Euphorbia are more sensitive to direct intense sun than true desert cactus, and all produce a milky white latex sap that is caustic and toxic — a health hazard that true cactus do not present.
How to tell: Squeeze or break a small piece of the plant. Cactus produce no sap; Euphorbia produce an instant flow of white latex. If white sap appears — it is a Euphorbia, not a cactus. Exercise caution: the latex causes skin irritation and severe eye damage. Wash hands immediately and keep away from eyes and children.
Moon Cactus — widely misunderstood
Gymnocalycium mihanovichii in its coloured grafted form (the vivid red, orange, or yellow ball on a green rootstock) is India’s most widely sold novelty cactus. It is routinely described as a single plant. In reality, it is two plants: the colourful top is a chlorophyll-free mutant that cannot survive independently, grafted onto a Hylocereus rootstock that provides photosynthesis for both. When the rootstock declines (typically after 2–5 years), the coloured top dies with it. This is normal — but buyers who don’t know this treat it as a plant failure.
Cereus — multiple species, one name
“Cereus” or “Column Cactus” in Indian markets covers at least three distinct species: Cereus peruvianus (the most common, ribbed blue-green column), Pilosocereus pachycladus (electric blue colour, distinctly different), and Cereus tetragonus “Fairy Castle” (small, multi-branching, does not flower). All are sold under “Cereus” or “Column Cactus” with identical care advice despite significantly different adult sizes and growth habits.
“Ferocactus” labels on Echinocactus
Golden Barrel Cactus (Echinocactus grusonii) is sometimes labelled “Ferocactus” in Indian markets — a different genus of barrel cactus with hook-tipped spines. The care is similar but not identical, and the adult appearance differs significantly. The identification is simple: E. grusonii has straight golden spines; true Ferocactus species have curved or hooked spines, often red or white.
20 Cactus Plant Names Available in India – The Complete Reference
Group 1 — Pad Cactus (Opuntia genus)
Opuntia ficus-indica — Indian Fig / Prickly Pear
Hindi name: Nagphani (नागफनी), Thoar (in some regions) Common names: Prickly Pear, Indian Fig, Barbary Fig, Cactus Pear Identification: Large, flat, oval pads up to 40 cm wide; areoles with small reddish-brown glochids and 1–4 white spines; edible fruit (the prickly pear / nagphani fruit) Adult size: 2–4 m tall in ground; manageable in large containers India availability: ★★★★★ — naturalised across Rajasthan, Maharashtra, Tamil Nadu; sold in virtually every physical nursery India significance: The most widespread cactus in India, introduced by colonial traders and now naturalised across multiple states. The fruit (prickly pear) is sold in Indian markets seasonally. The pads are edible after de-spining — used in some Rajasthani and rural cuisines.
Outdoor cactus plants India — Opuntia growing, monsoon management, and outdoor display guide
Opuntia microdasys — Bunny Ears Cactus
Hindi name: Khargosh kaan cactus (colloquial — rabbit ear cactus) Common names: Bunny Ears, Polka Dot Cactus, Angel Wings Identification: Small, oval pads in pairs; covered in fine yellow or white glochids but NO large spines (spineless variety); the paired pad shape resembles rabbit ears Adult size: 60–90 cm in containers India availability: ★★★★☆ — widely available online and in specialist nurseries Care note: The glochids (hair-like spines) are far more dangerous than they look — invisible, embed in skin instantly, intensely irritating. Handle only with thick gloves and tongs. Never allow children to touch.
Group 2 — Column Cactus
Cereus peruvianus — Peruvian Apple Cactus / Column Cactus
Hindi name: Khamb cactus (column cactus — colloquial), Stambh kaktus Common names: Peruvian Apple Cactus, Column Cactus, Night-Blooming Cereus (loosely applied) Identification: Multi-ribbed (typically 6–9 ribs), blue-green to grey-green column; areoles with brownish wool and 5–9 grey-brown spines; grows tall and straight, branching with age Adult size: 1–4 m+ in outdoor conditions; slower in containers India availability: ★★★★★ — the most widely available large cactus in India
Pilosocereus pachycladus — Blue Torch Cactus
Hindi name: Neela khamb cactus (blue column cactus — colloquial) Common names: Blue Torch Cactus, Blue Columnar Cactus Identification: The giveaway is colour — electric, vivid blue-grey stem with contrasting golden-yellow spines. If you have a distinctly blue columnar cactus, this is almost certainly the species. No other common Indian market cactus approaches this colour. Adult size: 3–6 m in ground; 60–120 cm in containers India availability: ★★★☆☆ — specialist sellers; increasingly available online
Cereus tetragonus — Fairy Castle Cactus
Hindi name: Pari ka mahal cactus (fairy castle — colloquial) Common names: Fairy Castle Cactus, Cereus hildmannianus Identification: Multiple short, branching arms growing in a clustered, castle-like silhouette; distinctly shorter and more branching than C. peruvianus; arms are 4-ribbed. Does not flower in cultivation. Adult size: 20–100 cm in containers — stays manageable India availability: ★★★★☆ — very common in Indian online markets; often the first “column cactus” Indian beginners encounter
Group 3 — Globe / Barrel Cactus
Echinocactus grusonii — Golden Barrel Cactus
Hindi name: Sona gola kaktus (golden barrel — colloquial) Common names: Golden Barrel Cactus, Mother-in-Law’s Cushion, Golden Ball Identification: Near-perfect sphere (slightly taller than wide in young plants, becoming more spherical with age); deeply ribbed; dense golden-yellow spines covering entire surface; no hooked spines (distinguishes from Ferocactus) Adult size: 40–80 cm diameter over many years — very slow India availability: ★★★★☆ — widely available; the most recognisable barrel cactus in India India significance: The most visually distinctive small to medium outdoor cactus for Indian terraces and gardens. The permanently golden colouration (from spines, not pigmentation) makes it identifiable from a distance.
Rare succulent plants India — Golden Barrel in the outdoor collection context
Ferocactus — Barrel Cactus (multiple species)
Hindi name: Kanta gola cactus (thorny ball cactus — colloquial) Common names: Barrel Cactus, Fish Hook Cactus, Devil’s Tongue Identification: Distinctly hooked or curved central spines — this is the defining identification feature. If the barrel cactus you are looking at has hook-tipped spines (curving back toward the plant), it is Ferocactus. If spines are straight, it is more likely Echinocactus grusonii. Adult size: 30–60 cm in Indian container conditions India availability: ★★★☆☆ — specialist sellers; less common than Golden Barrel
Gymnocalycium mihanovichii — Moon Cactus (grafted)
Hindi name: Rang-birange cactus (colourful cactus — colloquial), Chaand cactus Common names: Moon Cactus, Ruby Ball, Hibotan Cactus Identification: Colourful (red, orange, yellow, pink) globe on top of a green ribbed rootstock — unmistakable. The coloured portion is a chlorophyll-free mutant of G. mihanovichii; the green base is typically Hylocereus species. Adult size: 8–15 cm total — stays compact throughout its life India availability: ★★★★★ — the most widely available cactus in India; sold at roadside nurseries, supermarkets, Amazon, Flipkart
Gymnocalycium (ungrafted species)
Common names: Chin Cactus, Gymnocalycium Identification: Small, flattened globe; ribs divided into distinct “chin-like” protrusions beneath each areole — this chin feature is the genus identification marker. Flowers are funnel-shaped, typically pink, white, or purple, emerging from the crown. Adult size: 5–15 cm — excellent desk and windowsill cactus India availability: ★★★☆☆ — specialist sellers; growing availability
Mammillaria — Pincushion Cactus (multiple species)
Hindi name: Sui cactus (needle cactus — colloquial) Common names: Pincushion Cactus, Snowball Cactus (for woolly species), Fishhook Pincushion (hooked-spine species) Identification: Distinguished from all other Indian cactus genera by one key feature: the plant body is covered in spirally arranged tubercles (nipple-like projections), each bearing an areole at its tip. No other Indian market cactus shares this tuberculate (not ribbed) structure. Spines emerge from tubercle tips, not from ribs. Adult size: 3–20 cm depending on species; slow-growing India availability: ★★★★☆ — widely available; multiple species stocked by specialist sellers
Key India species:
- M. zeilmanniana — vivid magenta flowers, very reliable bloomer
- M. hahniana (Old Lady Cactus) — covered in white hair-like spines, pink-red flower ring
- M. elongata (Gold Lace Cactus) — elongated clustering form, cream-yellow flowers
- M. spinosissima — dense red-tipped spines, pink flower halo
Group 4 — Clustering and Sprawling Cactus
Echinopsis / Trichocereus — Torch Cactus
Common names: Torch Cactus, Easter Lily Cactus, Argentine Giant Identification: Ribbed, columnar to spherical form; large, showy flowers (the largest in proportion to plant size of any common Indian cactus); flowers emerge from lateral areoles on elongated tubes. The enormous flowers are the primary identification marker. Adult size: Variable — 30 cm to 1.5 m+ depending on species India availability: ★★★★☆ — widely available; often sold simply as “flowering cactus” Taxonomy note: Trichocereus was merged into Echinopsis in 2012 — both names appear in Indian markets; they refer to the same plants.
Rebutia — Crown Cactus
Common names: Crown Cactus, Red Crown Cactus Identification: Small, compact globe or clustering form; flowers emerge from the base or lower sides of the plant body — not from the crown (which distinguishes it from Mammillaria and Gymnocalycium). Vivid orange, red, or yellow flowers. Adult size: 5–12 cm — one of the smallest common Indian cactus India availability: ★★★☆☆ — specialist sellers
Group 5 — Epiphytic Cactus (Jungle / Forest Types)
Epiphyllum oxypetalum — Queen of the Night
Hindi name: Brahma Kamalam (ब्रह्म कमल), Nishagandhi (Kerala/South India), Dutchman’s Pipe Sanskrit name: Brahma Kamalam — Lotus of Brahma Common names: Queen of the Night, Orchid Cactus (loosely) Identification: Flat, leaf-like stems with scalloped edges — completely unlike any desert cactus. No true spines. Large white night-blooming flowers (15–20 cm) with intense fragrance. The flat stems are unmistakable. India availability: ★★★★★ — grown in homes across India; culturally embedded
Schlumbergera — Christmas Cactus / Holiday Cactus
Common names: Christmas Cactus, Thanksgiving Cactus, Holiday Cactus Identification: Flat, segmented stems with leaf-like pads that have serrated or pointed edges; pendulous tubular flowers in pink, red, white, or orange emerge from stem tips. The segmented, flat-stemmed form is distinctive. Adult size: 30–50 cm spreading — pendulous habit India availability: ★★★★☆ Care note: Epiphytic — requires more water and less direct sun than desert cactus. Treat as a tropical houseplant, not a desert plant.
Group 6 — Euphorbia Succulents Commonly Sold as Cactus in India
These are NOT true cactus but are widely sold as such in India. Included here specifically because Indian buyers frequently encounter them under cactus labels.
Euphorbia trigona — African Milk Tree
Hindi name: Thohar (in some regions), Teen kona cactus (three-corner cactus — colloquial) Common names: African Milk Tree, Cathedral Cactus, Friendship Cactus Why it’s confused with cactus: Three-winged columnar form with small spines looks very similar to a cactus to the untrained eye. Sold as “Column Cactus” or “Cactus” in many Indian nurseries. How to identify it’s NOT a cactus: White latex sap immediately on any damage; three distinct wings (not ribs); small oval leaves on the stem (cactus never have leaves). Safety: The latex sap is caustic. Causes skin irritation; severe eye damage if contacted. Wear gloves when handling. Keep away from children and pets.
Euphorbia neriifolia — Indian Spurge / Sehund
Hindi name: Sehund (सेहुंड), Thohar Sanskrit name: Snuhi Common names: Indian Spurge, Common Indian Spurge, Hedge Euphorbia Why it’s confused with cactus: Thick, spiny, leafless stems in the dry season look virtually identical to columnar cactus. One of the few plants with genuine ancient Indian names — it has been used in Ayurvedic medicine for centuries. Found growing wild in Indian scrubland. Cultural significance: Listed in Ayurvedic pharmacopoeias as Snuhi — used as a purgative in traditional medicine under strict dosing. External sap contact causes severe skin and eye irritation. Is it native to India? Yes — Euphorbia neriifolia is native to India and Southeast Asia, making it one of the very few “cactus-like” plants with genuine Indian origins.
Which Cactus Are Native to India?
A common and interesting question — and the answer surprises most buyers.
True cactus (family Cactaceae) are native only to the Americas. Not a single species in the Cactaceae family is indigenous to India, Asia, Africa, or Europe. Every cactus growing in India — from the Opuntia naturalised across Rajasthan to the Golden Barrel on your balcony — arrived from the Americas, directly or via colonial trade routes.
Opuntia in India: The most widely naturalised introduced cactus in India. Opuntia ficus-indica was introduced by Portuguese and British colonists from the 16th–18th centuries and has naturalised extensively across dry and semi-arid regions. It is so widespread in parts of Rajasthan, Maharashtra, and Tamil Nadu that many people assume it is native.
The plant that IS native and looks like cactus: Euphorbia neriifolia (Sehund) is native to India and has such a convincing cactus-like appearance that it was initially classified as one by early European botanists. It is listed in ancient Indian texts precisely because it is an indigenous plant with a long history of use — unlike true cactus, which have only been in India for 400–500 years.
How to Identify an Unlabelled Cactus from an Indian Nursery
This is the most practical section for most Indian buyers. You bought a cactus, it has no label, and you want to know what you have. Here is the systematic approach:
Step 1 — Establish that it is actually a cactus
Press or lightly damage a small inconspicuous part. If white latex sap appears — it is a Euphorbia, not a cactus. If clear to slightly green sap or no sap — proceed.
Look for areoles — the small, round or oval structures from which spines emerge. All true cactus have areoles; Euphorbia do not. If you can identify distinct areoles at the spine base, it is a cactus.
Step 2 — Identify the growth form
- Flat pads: Opuntia genus (Prickly Pear, Bunny Ears)
- Tall column, straight: Cereus, Pilosocereus, Echinopsis tall forms
- Short column, multi-branching: Cereus tetragonus (Fairy Castle), compact Echinopsis
- Globe or barrel: Echinocactus, Ferocactus, Gymnocalycium, Mammillaria, Parodia
- Flat leaf-like stems (no spines): Epiphyllum, Schlumbergera (epiphytic — not desert types)
- Densely tuberculate (nipple-covered, not ribbed): Mammillaria genus specifically
Step 3 — Check the spine character
- Straight spines from ribs: Cereus, Echinocactus, most columnar types
- Hooked or curved central spine: Ferocactus (hook-spine barrel cactus)
- Spines from areoles on tubercle tips (not ribs): Mammillaria
- Golden/yellow, dense, all straight: Echinocactus grusonii (Golden Barrel) — very distinctive
- No visible spines, only glochids (hair-like): Opuntia microdasys (Bunny Ears)
- Red or coloured spine tips: Mammillaria spinosissima or Ferocactus latispinus
Step 4 — Use identification apps
PlantNet (free, works in India): Upload a clear photo of the plant — different angles give better results. Works reasonably well for common Indian market cactus genera.
iNaturalist (free): Submit a photo with your location — the community of botanists identifies within hours. More accurate than automated apps for uncommon species. Works very well for Indian market cactus.
Google Lens: Useful for identifying common cactus but poor accuracy for species-level ID. Good enough to confirm genus (Mammillaria vs. Cereus vs. Opuntia); not reliable enough for species.
Step 5 — Match to care requirements
Once genus is established, apply the appropriate care:
- Opuntia, Cereus, Echinocactus, Ferocactus, Echinopsis: full outdoor direct sun, dry desert care
- Mammillaria, Gymnocalycium: bright sun but tolerate partial shade; compact size
- Epiphyllum, Schlumbergera: bright indirect light, more water, epiphytic care
- Any plant producing white latex sap: Euphorbia care (more sensitive, caustic sap safety protocol)

Frequently Asked Questions
Q1. What are the names of cactus plants in India?
The most common cactus plants in India include: Opuntia ficus-indica (Nagphani — Prickly Pear), Cereus peruvianus (Column Cactus), Gymnocalycium mihanovichii grafted (Moon Cactus), Echinocactus grusonii (Golden Barrel), Mammillaria species (Pincushion Cactus), Echinopsis (Torch Cactus), and Epiphyllum oxypetalum (Queen of the Night / Brahma Kamalam). Each has distinct care requirements — the botanical name is the most reliable way to find accurate care information.
Q2. What is the Indian name for cactus?
The word Kaktus (कैक्टस) is the most widely used term across all Indian languages — a direct transliteration used in Hindi, Marathi, Bengali, Telugu, Tamil, and others. The most culturally rooted Indian cactus name is Nagphani (नागफनी) — specifically for Opuntia pad cactus, and widely used in Hindi-speaking regions. Brahma Kamalam (ब्रह्म कमल) is the culturally significant name for Epiphyllum oxypetalum (Queen of the Night). Euphorbia plants sold as cactus in India are often called Sehund (सेहुंड) or Thohar in Hindi.
Q3. What is the most common cactus in India?
Opuntia ficus-indica (Prickly Pear / Nagphani) is arguably the most widespread cactus in India — it naturalised from colonial introductions and now grows semi-wild across Rajasthan, Maharashtra, and Tamil Nadu. In urban markets, Gymnocalycium mihanovichii in its grafted Moon Cactus form is the most widely sold cactus in India — available from roadside nurseries to supermarkets. Cereus peruvianus (Column Cactus) is the most common large cactus in Indian terrace gardens.
Q4. How do I identify my cactus in India?
The four-step approach: (1) confirm it is a cactus — press gently; white sap means it is a Euphorbia, not a cactus; (2) identify the growth form — flat pads (Opuntia), tall column (Cereus, Pilosocereus), globe/barrel (Echinocactus, Mammillaria, Gymnocalycium), or flat-stemmed (Epiphyllum, Schlumbergera); (3) check spines — straight vs. hooked, areoles from ribs vs. from tubercles; (4) use PlantNet or iNaturalist apps for photo-based confirmation.
Q5. What is cactus called in Hindi?
Kaktus (कैक्टस) is the standard Hindi term, used across India. Nagphani (नागफनी) specifically refers to Opuntia pad cactus. Brahma Kamalam (ब्रह्म कमल) is the culturally significant name for Queen of the Night (Epiphyllum oxypetalum). Sehund (सेहुंड) refers to Euphorbia neriifolia — a common Indian succulent plant that resembles cactus but is not botanically a cactus.
Q6. Which cactus is found naturally in India?
No true cactus (family Cactaceae) is native to India — all are introduced from the Americas. Opuntia ficus-indica is the most widely naturalised, established across semi-arid Indian regions over 400+ years. The plant that IS native to India and resembles a cactus is Euphorbia neriifolia (Sehund) — an indigenous Indian plant with ancient Sanskrit names and Ayurvedic uses. It is a succulent Euphorbia, not a true cactus, but its spiny, leafless form convincingly mimics one.
Q7. Why does my “cactus” produce white sap?
White latex sap means it is a Euphorbia plant — commonly sold as cactus in India but belonging to a completely different plant family. Common Indian Euphorbia sold as cactus include: Euphorbia trigona (African Milk Tree), Euphorbia neriifolia (Indian Spurge / Sehund), and Euphorbia tirucalli (Pencil Cactus). The care is broadly similar to true cactus, but the latex sap is caustic — causes skin irritation and severe eye damage. Always wear gloves when handling, wash hands thoroughly after contact, and keep away from children and pets.
Q8. What is the difference between cactus and succulent?
All cactus are succulents — they store water in their bodies. But not all succulents are cactus. The defining feature of true cactus is areoles — specialised structures from which spines, flowers, and new growth emerge. No other succulent plant has areoles. Aloe vera, Jade Plant, Haworthia, and Euphorbia are all succulents but are not cactus. In Indian plant markets, “cactus” and “succulent” are often used interchangeably — botanically they are a subset relationship, not synonyms.
