Myrtillocactus Geometrizans Forma Cristata, commonly known as the Dinosaur Back Plant, is a rare and striking cactus native to the arid regions of central and northern Mexico. In its natural habitat, this plant thrives on rocky hillsides and scrublands, where it enjoys plenty of sunlight and well-draining soil. These environments have minimal rainfall. They are typically dry with high temperatures, perfect conditions for this hardy succulent., so this plant has adapted to drought and harsh conditions.
One of the standout features of the Dinosaur Back Plant is its beautiful blue-green color and solid, wax-like texture. Unlike the standard Myrtillocactus Geometrizans, which grows upright with cylindrical branches, Dinosaur Back cactus has crested growth form. The crested form develops a fascinating fan-like structure due to a genetic mutation. This mutation gives the plant a unique, intertwined appearance that looks a lot like a dinosaur's back, which is how it got its name. In the wild, these plants can grow up to 15 feet tall with a crown spreading up to 16 feet wide, forming a striking tree-like trunk that clusters together.
Dinosaur Back cactus isn't just any plant. It's a fascinating and beautiful addition to any home or garden. Its unique appearance, rarity, and ease of care make it a favorite among those who appreciate the diverse beauty of the plant world.
Toxicity
Myrtillocactus Geometrizans Forma Cristata, or Dinosaur Back Plant, is not considered toxic to humans or pets. This makes it a perfect pet-friendly houseplant and a great choice for households with children or animals. However, as with all plants, it's a good idea to keep an eye on pets or young kids to ensure they don't chew on the plant. Even non-toxic plants can sometimes cause mild digestive upset if ingested. Always wash hands after handling plants, especially if you've been pruning or propagating, to avoid any potential skin irritation from the plant's sap.
General Care
1. Lighting
Place it near a south or east-facing window where it can receive plenty of natural light. However, be cautious of direct sunlight, which can be too intense and may scorch the plant. If direct sunlight is unavoidable, try to use sheer curtains to filter the light. In cases where natural light is limited, supplement with a grow light to mimic the conditions it would get outdoors. A grow light should ideally be placed about 6-12 inches above the plant and left on for about 12-14 hours a day to ensure it receives adequate light.
When grown outside, Dinosaur Back cactus should be positioned in a location with bright, indirect sunlight. It can handle some direct sunlight, especially in the morning, but prolonged exposure to intense afternoon sun might lead to sunburn. A spot with filtered sunlight or partial shade is ideal. If you're in a particularly hot climate, it’s best to provide some protection from the harshest sun to prevent damage.
2. Watering
Dinosaur Back Plant prefers a dry environment. Water it thoroughly but infrequently. Allow the top 2-3 inches of soil to dry out before watering again. In general, this may mean watering every 2-4 weeks, but adjust based on the humidity levels in your home. During the winter months, when light levels are lower and the plant's growth slows down, reduce the frequency of watering even further. Be careful not to overwater, as this can lead to root rot. Ensure that the pot has good drainage to help excess water escape and prevent waterlogging.
For outdoor cacti, watering needs can vary significantly based on the climate. In regions with hot, dry climates, Dinosaur Back Plant will need more frequent watering compared to indoor settings. Water deeply but allow the soil to dry out between waterings. It’s essential to adjust the watering frequency based on rainfall and ensure the soil has good drainage to prevent water from accumulating around the roots. In both indoor and outdoor settings, always check the soil moisture before watering.
3. Soil And Fertilizer
Dinosaur Back Plant thrives in well-draining soil. A mix specifically designed for cacti and succulents is ideal, as it ensures proper drainage and prevents water from accumulating around the roots. You can create your own mix by combining regular potting soil with perlite, sand, or pumice to improve aeration and drainage. A ratio of 1 part potting soil to 1 part perlite and 1 part sand or pumice works well. For outdoor plants, choose a location with sandy or gravelly soil that drains well. If your soil is heavy or clayey, consider amending it with coarse sand or gravel to enhance drainage. In containers, always use pots with drainage holes to prevent waterlogging and root rot.
As a cactus, this plant does not need frequent or heavy fertilizing. However, if you want to boost its growth, you can feed your Dinosaur Back Plant with a balanced, diluted cactus or succulent fertilizer during the growing season (spring-summer). Use a general-purpose fertilizer with a ratio like 10-10-10, or a specialized cactus formula. Apply the fertilizer every 4-6 weeks. In the fall and winter, when the plant's growth slows down, stop fertilization, as the plant needs less nutrition during this dormant period.
4. Temperature And Humidity
This cactus enjoys warmth and should be kept in temperatures between 60-80°F. It can tolerate a slight drop in temperature but should not be exposed to temperatures below 50°F for extended periods. During the winter, avoid placing the plant near drafts, heaters, or cold windows, as sudden temperature fluctuations can stress this plant. If grown outdoors, Dinosaur Back Plant prefers a warm, dry climate. In regions with colder winters, it’s best to bring the plant indoors or provide some form of protection from frost.
Dinosaur Back Plant is adapted to low humidity environments and prefers dry air. Maintaining humidity levels around 30-50% is ideal. High humidity can lead to problems like fungal infections and root rot. To keep humidity in check, ensure good air circulation around the plant and avoid overwatering.
Extra Care
1. Potting And Repotting

When potting or repotting Dinosaur Back Plant, it's important to use a well-draining soil mix, typically a cactus or succulent blend, to prevent waterlogging and root rot. Choose a pot with drainage holes to ensure excess water can escape. When repotting, select a container slightly larger than the current one to accommodate growth but avoid going too large, as excess soil can retain too much moisture. Gently remove the plant from its old pot, shake off any excess soil from the roots, and place it in the new pot, filling in with fresh soil. After repotting, allow the plant to settle for a few days before resuming its regular watering schedule to give the roots time to adjust.
2. Pruning
Most cacti and succulents are slow growers and do not need frequent pruning. However, pruning still helps to remove dead or damaged growth, encourage a compact and attractive shape, and manage the plant's size. It can also help improve air circulation and prevent the development of pests and diseases. The best time to prune your Dinosaur Back Plant is during the growing season, typically from spring to early summer. Pruning during this period allows the plant to recover and grow back more vigorously. Avoid heavy pruning and stop pruning during the winter months when the plant is in its dormant phase. Always use clean, sharp tools to make precise cuts and reduce the risk of introducing diseases. Sterilize your pruning tools with rubbing alcohol before and after use to maintain cleanliness.
3. Propagation
Propagation of the Dinosaur Back Plant can be done through offsets or cuttings. To propagate from offsets, first, identify small, mature growths at the base of the main plant. Use sterilized tools to separate the offsets from the main plant, then let the cut ends dry and form a callus for a few days to prevent rot. Once callused, plant the offsets in a well-draining cactus mix, water lightly, and place in a warm, bright location with indirect sunlight. Alternatively, you can propagate from cuttings by taking a healthy section of the plant, allowing it to dry and callus, then planting it in a suitable soil mix. Care for both offsets and cuttings involves watering sparingly, providing bright indirect light, and maintaining a warm temperature. Ensure tools are sterilized and be patient, as propagation can take time.
4. Blooming
In the summer, Dinosaur Back Plant bursts into bloom with cream-colored flowers, followed by tiny, sweet, plum-like fruit. To encourage flowering, ensure the plant receives plenty of bright, indirect light and is kept in a stable environment with appropriate watering and care. However, flowering is not a primary attraction for this plant; its striking, crest-like growth and unusual shape are what make it truly special.
Common Problems
Dinosaur Back Plant can face a few common issues, despite being relatively hardy. One major problem is overwatering, which can lead to root rot. This is often indicated by yellowing or mushy leaves and a generally unhealthy appearance. It’s crucial to let the soil dry completely before watering again. On the other hand, if the plant isn’t watered enough, it can become dehydrated, showing up as shriveled or wrinkled stems. Adjusting the watering schedule according to the plant's needs and the environmental conditions can help prevent this.
Another issue to watch for is insufficient light. If the plant doesn’t receive enough light, it may become leggy and lose its vibrant look. Ensure it gets bright, indirect light or direct sunlight to stay healthy. Pest infestations, such as spider mites and mealybugs, can also occur. Signs include webbing, white cotton-like clusters, or damage to the plant. Prompt treatment with insecticidal soap or neem oil can help manage these pests.
Temperature stress is another concern; the plant can suffer from extreme temperatures. It should be kept in a range that avoids freezing conditions and excessive heat. In colder climates, protect it from frost, and in hot climates, provide some shade to prevent sunburn.
