You picked up a cute succulent at the store, but what genus is it? Most succulents are sold with vague labels like "assorted succulent" or just a color name. Knowing the genus tells you whether it can survive frost, whether it is safe around pets, and what care routine it actually needs. The chart below compares 11 common succulent genera side by side so you can identify yours by the features you can see from across the room.
Match your plant against the columns below. Leaf shape and growth habit narrow it down fastest; the lookalikes column helps rule out close relatives.
| Genus | Common Name | Leaf Shape | Growth Habit | Key Colors | Closest Lookalike | Frost Hardy | Pet Safe |
|---|---|---|---|---|---|---|---|
| Echeveria | Mexican Snowball, Hen & Chicks* | Thick, spoon-shaped; often farina-coated | Symmetrical rosette, 2-12" wide | Blue-green, pink, lavender, purple | Sempervivum, Graptoveria | No | Yes |
| Sempervivum | Hens and Chicks, Houseleek | Thin, pointed; some varieties webbed with "cobweb" hairs | Tight ground rosette; spreads by stolons | Green, red, bronze, purple with colored tips | Echeveria | Yes (to -30 F) | Yes |
| Haworthia | Zebra Plant, Pearl Plant | Short, pointed; translucent windows or white tubercles | Compact clump, 2-5" | Dark green with white bands or dots | Aloe (small), Gasteria | No | Yes |
| Sedum | Stonecrop, Burro's Tail, Jelly Bean | Bean-shaped, cylindrical, or flat depending on species | Trailing, creeping, or upright | Green, blue-green, red-tipped (S. rubrotinctum) | Crassula, Graptosedum | Varies by species | Mostly yes* |
| Crassula | Jade Plant, String of Buttons | Oval (Jade) or stacked triangular pairs along stem | Branching tree-like (Jade) or stacked column | Bright green, red-edged under full sun | Portulacaria, some Sedums | No | Toxic |
| Aloe | Aloe vera, Tiger Aloe | Long, lance-shaped with soft teeth; gel-filled | Rosette, clumping; can grow 1-3 ft tall | Gray-green to blue-green, spotted in some species | Haworthia (small), Agave, Gasteria | Some species | Toxic |
| Agave | Century Plant, American Aloe | Stiff, fibrous, with a sharp terminal spine and serrated edges | Large rosette, 1-10 ft; monocarpic | Blue-green, gray-green, variegated | Aloe (large), Yucca | Often yes (to 0 F or below) | Generally yes |
| Kalanchoe | Flaming Katy, Panda Plant | Flat, oval, scalloped (Flaming Katy) or fuzzy-felt (Panda) | Upright, branching; 6-18" tall | Green, often red-margined; gray-fuzzy (Panda Plant) | Crassula, Bryophyllum | No | Toxic |
| Gasteria | Ox Tongue, Lawyer's Tongue | Tongue-shaped, thick, often white-spotted | Fan-shaped or rosette; compact, 4-12" | Dark green with white spots or raised bumps | Haworthia, Aloe | No | Yes |
| Euphorbia | Crown of Thorns, African Milk Tree | Highly variable; milky sap when cut is the key identifier | Columnar, branching, or spreading | Green, gray-green, ribbed stems | Cacti, columnar Aloe | Varies | Toxic (all) |
| Portulacaria | Elephant Bush, Dwarf Jade | Tiny, round, fleshy on reddish-brown stems | Branching shrub; resembles a miniature Jade Plant | Bright green on burgundy or red stems | Jade Plant (Crassula ovata) | No | Yes |
* "Hen and Chicks" is used for both Echeveria and Sempervivum. Sempervivum is the frost-hardy outdoor species. Sedum toxicity varies by species; check ASPCA for the exact species before placing it near pets.

Identify Your Succulent →The quintessential succulent rosette. Echeverias are probably what you picture when someone says "succulent."
Popular species: E. elegans (Mexican Snowball), E. 'Lola', E. 'Perle von Nurnberg' (purple), E. agavoides (Lipstick Echeveria).
Often confused with Echeveria, but Sempervivums are cold-hardy outdoor succulents.
Echeveria vs. Sempervivum: Echeveria has thicker, smoother leaves and is not frost-hardy. Sempervivum has thinner, pointier leaves, produces offsets on stolons, and survives extreme cold.
Small, compact succulents perfect for windowsills and desks.
Popular species: H. fasciata (Zebra Plant), H. cooperi (transparent tips), H. retusa.
A huge genus with species ranging from tiny ground covers to tall upright plants.
Popular species: S. morganianum (Burro's Tail), S. rubrotinctum (Jelly Bean Plant), S. adolphii (Golden Sedum).
A diverse genus best known for the Jade Plant.
Popular species: C. ovata (Jade Plant), C. perforata (String of Buttons), C. 'Buddha's Temple'.
Many popular succulents are hybrids between genera: Graptoveria (Graptopetalum x Echeveria), Pachyveria (Pachyphytum x Echeveria), and Graptosedum (Graptopetalum x Sedum). These can be the hardest to identify precisely because they blend features of both parents.
Agaves are large, architectural succulents most often seen in xeriscape gardens and warm climates. They are monocarpic, meaning the mother plant flowers once and dies, though it usually produces offsets (pups) beforehand.
Kalanchoe is one of the most common flowering succulents sold at grocery stores and garden centers, best known as Flaming Katy. The genus also includes fuzzy, velvety-leaved species like the Panda Plant.
Gasterias are slow-growing, shade-tolerant succulents that are often overlooked but make excellent low-light houseplants. They are closely related to Aloe and Haworthia and are sometimes sold mislabeled as one or the other.
Euphorbia is one of the largest plant genera on Earth and includes both succulent and non-succulent species. Succulent Euphorbias are often mistaken for cacti because some grow in columnar, ribbed, spine-covered forms.
Portulacaria afra is frequently sold as "Dwarf Jade" and is one of the most common succulent mix-ups for new plant owners. It is not a Jade Plant (Crassula ovata), though it resembles one, and it is actually pet-safe where Crassula is toxic.
Not sure which genus fits your plant?

Once you have identified your succulent genus, care is generally similar across most species:
Not sure how often to water your succulent? Use our plant watering schedule calculator, select "Succulent/Cactus" as the plant type and it will factor in your pot type, climate, and season.
For more detailed plant care, see our beginner's houseplant care guide.
Getting the soil and pot right is the biggest factor in succulent success. Most succulent deaths come from too much water sitting in dense, slow-draining soil; these products fix that.
Examine the leaf shape, rosette pattern, color, and texture. The fastest method is to use the identification chart above to compare genera side by side, or to snap a photo with our plant identifier for an instant AI-powered identification.
Echeveria has thicker, smoother leaves and is not frost-hardy. Sempervivum has thinner, pointed leaves, produces offsets on stolons, and survives extreme cold (to -30 F).
Some are safe (Haworthia, Echeveria, Sempervivum, Gasteria, Portulacaria) while others are toxic (Jade Plant/Crassula, Aloe, Kalanchoe, Euphorbia). Always identify your species and check toxicity. See our guides on plants safe for cats and dogs. The Pet Safe column in the chart above gives a quick overview across all 11 genera.
Haworthia is the genus best known for this feature, called leaf windows or fenestrations. H. cooperi and H. truncata show them most clearly; the windows look like tiny glass panels set into the leaf tip. This is the most distinctive visual cue in the genus and is not seen in Aloe, Gasteria, or Echeveria.
All cacti are succulents, but not all succulents are cacti. The distinguishing feature is the areole: a small woolly or bristly bump found only on cacti, from which spines, flowers, and new branches grow. If your plant has areoles, it is a cactus. If spines grow directly from the stem with no areole (as in Euphorbia or Agave), it is not a cactus. Aloe, Haworthia, Agave, and Euphorbia are often mistaken for cacti but belong to entirely different families.
Several genera develop red or orange tips under stress from high light, temperature swings, or drought. The most reliably red-tipped is Sedum rubrotinctum (Jelly Bean Plant), whose plump bean-shaped leaves stay red at the tips year-round. Echeveria agavoides (Lipstick Echeveria) has a distinct red leaf margin. Crassula ovata develops red edges in full sun. In most genera the red color is an anthocyanin stress response that fades when the plant returns to lower light or more consistent watering.
