Many dog owners, especially those new to succulent gardening, often confuse the dog tail cactus ( Epiphyllum anguliger) with the dragon fruit plant (Hylocereus undatus). While both are captivating plants with unique appearances and belong to the cactus family, they are distinct species with differing care needs. Understanding these differences is crucial, especially if you have curious canine companions who might be tempted to nibble on these intriguing plants.
Distinguishing Features: Dog Tail Cactus vs. Dragon Fruit
So, how can you tell these two apart? The most obvious difference lies in their stems. The dog tail cactus, true to its name, has flattened, zig-zagging stems resembling a dog’s tail. These stems are spineless and have a deep green hue. The dragon fruit, on the other hand, features triangular, climbing stems with pronounced spines. These stems are often a lighter green and can grow much longer and more aggressively than the dog tail cactus.
Another key differentiator is the flower. Both plants produce stunning blooms, but they vary significantly in appearance. The dog tail cactus boasts large, fragrant, white or cream-colored flowers that bloom at night. Dragon fruit flowers are also large and impressive, typically white with yellowish centers, and also bloom nocturnally. However, the dragon fruit flower is more elongated and pointed compared to the broader, more open flower of the dog tail cactus.
Toxicity and Pet Safety
Are these plants safe for our furry friends? While the dog tail cactus is generally considered non-toxic to dogs, the sap can cause mild skin irritation or gastrointestinal upset if ingested in large quantities. The dragon fruit is also non-toxic to dogs, and in fact, the fruit itself is a safe and healthy treat in moderation. However, the spines on the dragon fruit plant can pose a physical hazard, causing injuries if your dog gets too close.
It’s always best to keep these plants out of your dog’s reach, especially if your dog is prone to chewing on plants. Supervise your dog closely when they are around these plants, and consider using pet-friendly deterrents to discourage nibbling.
Care Requirements: Tailoring Your Approach
Both the dog tail cactus and the dragon fruit thrive in warm, sunny conditions. However, the dragon fruit requires more space and support for its climbing stems, often needing a trellis or other structure to climb on. The dog tail cactus, being smaller and less vigorous, can be happily grown in hanging baskets or pots.
Watering needs also differ. The dog tail cactus prefers a slightly drier environment, while the dragon fruit requires more frequent watering, especially during the growing season. Both plants benefit from well-draining soil to prevent root rot.

Is dog tail cactus poisonous to dogs?
