Poisonous Plants to Avoid on Pet-Friendly Properties

Aloe Vera

This beautiful medicinal plant is a staple of many landscapes thanks to its unique appearance and multi-use pulp. Where Aloe Vera can help heal humans, it is actually dangerous for dogs to consume. From vomiting to central nervous system issues, the issues that may occur when pups eat this otherwise lovely plant are extensive and best avoided–don’t include these for a pet-friendly landscape.


With gorgeous vibrant blooms, it is clear why these ornamental plants are popular as both indoor and outdoor décor. However, the bulbs contain alkaloid lycorine. When consumed by pets, the effects can be serious—sometimes even fatal. As such, it is best to save these admittedly beautiful flowers for properties without pets. This is not a good choice for a pet-friendly landscape.


With the ability to provide striking contrast and color year-round, Begonias are a common sight on well-appointed properties. Despite the pizazz they can add to a landscape, you should seek the attention of a vet immediately if they are consumed by your pet. This is due to the raphides, a type of calcium oxalate, that are contained within the plant. Consider these a no-no for a pet-friendly landscape.

Baby’s Breath

With unmistakable white blooms that would look at home at any wedding, Baby’s Breath is a lovely addition to any landscape that is not home to pets. They may look ethereal and harmless, but they can cause serious digestive issues that can make your pet extremely sick. So, please don’t include these in your pet-friendly landscape.


Popular thanks to their vivid blooms, Daffodils, unfortunately, suffer from the same pet-related issue as Amaryllis. The bulbs contain chemicals that severely impact the health of your pet, leading to potentially deadly conditions. As stunning as these Spring flowers are, they should be avoided at all costs if your property is shared with a furry friend.

Peace Lily

Deep green foliage complements bright white petals when these timeless flowers bloom. Peace Lilies are magnificent and are a wonderful inclusion in any landscape not frequented by canine or feline companions. They contain calcium oxalate crystals, similar to Begonias, that can cause dangerous adverse reactions in pets that consume them.

Sago Palm

Perfect for accenting other palms or creating visual texture along walkways, Sago Palms are renowned for their rich green coloring and bush-like tropical appearance. While they can harm humans with their relatively sharp needles, all parts of Sago Palms are toxic to pets. If consumed, liver failure and death can occur, making these iconic Florida plants a must-avoid for pet owners.
