What comes to your mind when you think of cacti? Well, many people view cacti as prickly plants with sharp spines. But did you know that not all cacti have spines? In fact, there are more than 1,500 species of cacti, and only a small percentage of them are armed with spines.
So, what are some of the common types of cacti that don’t have spines?
The most common spineless cactus is the Christmas cactus (Schlumbergera truncata). This tropical plant is native to Brazil and features segmented stems with colorful flowers. Another popular type of spineless cactus is the Easter cactus (Rhipsalidopsis gaertneri), which is closely related to the Christmas cactus. Other notable spineless cacti include the orchid cactus (Epiphyllum), queen of the night (Peniocereus greggii), and old man cactus (Cephalocereus senilis).
Read on to learn ten types of cacti that don’t have spines and their other characteristics.
1. Christmas cactus (Schlumbergera truncata)
Christmas cactus is the most popular type of spineless cactus. This tropical plant is native to Brazil and features segmented stems with colorful flowers. The plant gets its common name from the fact that it blooms around Christmas time.
Christmas cactus is relatively easy to care for and makes a great houseplant. When growing indoors, place the plant in a bright spot but out of direct sunlight.
The best time to water Christmas cactus is when the soil is dry to the touch. Christmas cactus is also relatively tolerant of drought and can go long periods without water.
Once the plant blooms, it will likely start to drop its flowers. This is normal and doesn’t mean that the plant is dying. To encourage more blooms, give the plant a cool period (50-60° F) for about four weeks in the fall.
2. Easter cactus (Rhipsalidopsis gaertneri)
The Easter cactus is another popular type of spineless cactus. This succulent is closely related to the Christmas cactus and shares many of the same features. The Easter cactus is native to Brazil and gets its common name from the fact that it blooms around Easter time.
The Easter cactus is relatively easy to care for. When growing indoors, place the plant in a bright spot but out of direct sunlight. Water the plant when the soil is dry to the touch. Easter cactus is also relatively tolerant of drought and can go long periods without water.

You also need to be careful with the amount of fertilizer you give Easter cactus. Too much fertilizer can damage the plant’s roots and prevent it from blooming.
3. Mammillaria lasiacantha

This cactus is easy to care for and makes a great houseplant. Place it in a bright spot but out of direct sunlight. Allow the soil to dry out completely between watering sessions. Water it less often during winter.
Mammillaria lasiacantha is not susceptible to many pests or diseases, but mealybugs can be a problem. The best way to protect your plant from mealybugs is to keep an eye out for them and treat them with insecticidal soap or neem oil as soon as you spot them.
4. Orchid cactus (Epiphyllum)
The orchid cactus is a type of spineless cactus that is native to Central and South America. This plant gets its common name from its showy flowers resembling orchids. Orchid cacti are also sometimes called epiphyllum cacti.

6. Queen of the night (Peniocereus greggii)
