Is the Russian Arborvitae Poisonous?

Toxic or Not?

• Also known as the Siberian cypress, the Russian arborvitae is not classified as being toxic. Still, that doesn't mean it won't pose a danger to curious pets, who may be tempted to nibble on the branches and foliage. And just because a plant is not poisonous doesn't mean it won't hurt your furry friend: Non-toxic plants still can cause stomachaches and vomiting in dogs and cats, according to Morris Veterinary Center. If you find Fido chewing on your Russian arborvitae, and he seems ill afterward, contact your veterinarian immediately.

Attractive Arborvitae

• The fact that the Russian arborvitae is not poisonous is a definite plus, but the plant has other positive qualities as well. The stacked, arching branches, which droop slightly at the tips, give the plant a graceful appearance. One Russian arborvitae can grow to a maximum height of around 2 feet and a maximum spread of about 12 feet. In the winter, the muted green branches change to bronze or burgundy. Because of this, the plant may appear as if it has died, but this is normal for a Russian arborvitae. It will green up again in the spring in most cases.

Climate and Culture

• The Russian arborvitae is a cool-climate plant. It thrives in U.S. Department of Agriculture plant hardiness zones 2 through 8, according to the North Carolina State University Cooperative Extension Service. The plant grows equally well in sun or part-shade but needs consistently moist soil that drains well to look its best. It does not tolerate hot, dry locations very well.

Amazingly Adaptable

• Although it does not enjoy overly wet or dry conditions, the Russian arborvitae adapts to all types of soil, is very cold hardy and is an excellent choice for shady areas, according to the University of Rhode Island Cooperative Extension. Other than as a specimen plant or attractive ground cover, Russian arborvitae can also be used to stifle weed growth or stabilize soil.
