What Is the Devil’s Backbone Plant?
The devil’s backbone plant is a member of the Crassulaceae family, which includes other popular succulents like jade plants and echeverias. It’s a perennial succulent that can grow up to 3 feet tall, though it typically stays smaller when grown indoors. The plant’s most distinctive feature is its fleshy, gray-green leaves edged with tiny plantlets—miniature versions of the parent plant that drop off and root wherever they land. This natural propagation method makes it incredibly easy to grow new plants, even for beginners.
While the devil’s backbone is often grown as a houseplant, it can also thrive in outdoor gardens in warm climates (USDA zones 9–11). It prefers warm temperatures and doesn’t tolerate frost, so if you live in a cooler region, it’s best kept indoors or brought inside during winter. The plant is also known by other names, including mother of thousands, alligator plant, and Mexican hat plant—each reflecting a different aspect of its appearance or behavior.
One of the most fascinating traits of this plant is its reproductive strategy. Unlike most plants that rely on seeds, the devil’s backbone produces new plants directly from its leaves. These tiny plantlets develop along the leaf margins and can fall off at the slightest touch, quickly colonizing nearby soil. While this makes propagation a breeze, it also means the plant can become invasive in the wild—so be mindful if planting outdoors.
Devil’s Backbone Plant Flower: What to Expect
Now, let’s talk about the main event: the devil’s backbone plant flower. While this succulent is primarily admired for its foliage, it does produce flowers under the right conditions—though blooming is relatively rare, especially indoors. When it does flower, the plant sends up a tall, upright stalk that can reach 12 to 18 inches in height. From this stalk, clusters of small, bell-shaped flowers emerge, usually in shades of pink, purple, or white.
The flowering process typically occurs in late winter or early spring, after the plant has reached maturity—usually around 2 to 3 years of age. However, indoor conditions often lack the specific light and temperature cues needed to trigger blooming. To encourage flowering, you’ll need to mimic the plant’s natural environment as closely as possible. This includes providing long periods of darkness (14 hours per day) for several weeks, followed by increased daylight. This mimics the shorter days of winter and longer days of spring, signaling the plant to bloom.
It’s important to note that once the devil’s backbone plant flowers, it often begins to decline. This is because the plant puts a tremendous amount of energy into producing the bloom, and after flowering, it may not recover fully. However, don’t despair—by this time, you’ve likely already propagated several new plants from the leaf margins, ensuring the legacy of your original plant continues.
Ideal Growing Conditions
To keep your devil’s backbone plant happy and healthy, it’s essential to provide the right growing conditions. Fortunately, this succulent is quite adaptable and forgiving, making it ideal for both novice and experienced gardeners.
Light Requirements
The devil’s backbone plant thrives in bright, indirect sunlight. A south- or west-facing window is ideal, as it provides plenty of light without the harsh midday sun that can scorch the leaves. If you notice the leaves becoming pale or stretched out, it’s a sign the plant isn’t getting enough light. On the other hand, if the leaves start to turn red or brown at the edges, it may be getting too much direct sunlight.
For outdoor growers, partial shade is best—especially in hotter climates. Morning sun with afternoon shade will help prevent leaf burn while still providing enough light for healthy growth.
Soil and Potting
Like all succulents, the devil’s backbone plant hates soggy roots. It needs well-draining soil to prevent root rot, a common issue with overwatering. A commercial cactus or succulent mix works perfectly, or you can make your own by combining regular potting soil with perlite, pumice, or coarse sand (aim for a 50/50 ratio).
When choosing a pot, make sure it has drainage holes. Terra cotta pots are a great option because they’re porous and help wick away excess moisture. Avoid oversized pots—succulents prefer to be slightly root-bound, and too much soil can retain water longer than necessary.
Watering Tips
Watering is where many plant owners go wrong. The key is to water deeply but infrequently. Allow the soil to dry out completely between waterings—stick your finger about an inch into the soil; if it feels dry, it’s time to water. During the growing season (spring and summer), you may need to water every 2–3 weeks. In fall and winter, reduce watering to once a month or less, as the plant enters a dormant phase.
Overwatering is the number one cause of death for succulents. Yellowing or mushy leaves are clear signs of too much water. If you suspect root rot, remove the plant from its pot, trim away any black or soft roots, and repot in fresh, dry soil.
Temperature and Humidity Preferences
The devil’s backbone plant prefers warm, dry conditions—much like its native Madagascar. Ideal temperatures range from 65°F to 80°F (18°C to 27°C). It can tolerate brief dips down to 50°F (10°C), but prolonged exposure to cold can damage or kill the plant. Avoid placing it near drafty windows, air conditioners, or heaters, as sudden temperature changes can stress the plant.
Humidity isn’t a major concern for this succulent. In fact, it prefers lower humidity levels, typical of most indoor environments. If you live in a very humid climate, ensure good air circulation around the plant to prevent fungal issues.
Fertilizing and Maintenance
While the devil’s backbone plant isn’t a heavy feeder, a little fertilizer during the growing season can encourage stronger growth and potentially better flowering. Use a balanced, water-soluble fertilizer diluted to half strength, applied once a month from spring through early fall. Avoid fertilizing in winter when the plant is dormant.
Regular maintenance includes removing dead or damaged leaves and keeping an eye out for pests. Common pests include mealybugs and spider mites, which can be treated with insecticidal soap or neem oil. Wipe the leaves occasionally with a damp cloth to keep them dust-free and allow for better photosynthesis.
Propagation: Growing New Plants
One of the most exciting aspects of the devil’s backbone plant is how easy it is to propagate. As mentioned earlier, tiny plantlets form along the edges of the leaves. These can be gently snapped off and placed on top of moist soil. Within a few weeks, they’ll develop roots and begin growing into new plants.
Alternatively, you can propagate from stem cuttings. Simply cut a healthy stem about 3–4 inches long, let it callous over for a day or two, then plant it in well-draining soil. Keep the soil lightly moist until roots form, then treat it like a mature plant.
This natural propagation method means you can quickly build a small collection of devil’s backbone plants—or share them with friends and family. Just remember: because the plantlets can spread easily, it’s best to grow this succulent in containers to prevent unintended spreading in gardens.
Common Problems and Solutions
Even with the best care, issues can arise. Here are a few common problems and how to fix them:
- Leaf drop: Often caused by overwatering or sudden temperature changes. Check soil moisture and adjust watering habits.
- Pests: Mealybugs and spider mites love succulents. Inspect regularly and treat with neem oil if needed.
- Leggy growth: Indicates insufficient light. Move the plant to a brighter location.
- No flowering: Usually due to lack of light or improper light cycles. Try providing longer dark periods in winter.
- Root rot: Caused by poor drainage or overwatering. Repot in fresh, dry soil and reduce watering.
Is the Devil’s Backbone Plant Safe?
While beautiful, the devil’s backbone plant is toxic to pets and humans if ingested. It contains compounds called bufadienolides, which can cause vomiting, diarrhea, and heart irregularities in cats and dogs. Keep the plant out of reach of curious pets and small children. If ingestion is suspected, contact a veterinarian or poison control immediately.
