Topic: Poisonous Plants, Shrubs
Title: Shrubs not toxic to cattle in NJ
Answered by: Anne Bossart

QUESTION:

I am working to rejuvenate the hedgerows on a farm in New Jersey by removing invasive plants and planting native shrubs. How do I find out which native shrubs are toxic to cattle and should not be planted in the hedgerows?

ANSWER:

We applaud your efforts.  By removing inavsive plants and planting native shrubs you are providing important (and at times scarce) habitat food and shelter for many native species of birds, insects and small mammals.

The Cornell University Department of Animal Science has a published an extensive list of plants that are poisonous to livestock.  Click here for the list of plants poisonous to cattle.  When you examine it closely you will see that most of them are herbaceous plants but many of them are native to your area that could get established within your hedgerow

Allium canadense (Meadow garlic)

Asclepias syriaca (Common milkweed)

Phytolacca americana (American pokeweed)

There are actually not many shrubs on the list that you would be considering but there are a  few you should avoid, such as:

Aesculus parviflora (Bottlebrush buckeye) whose fruits are poisonous

Prunus serotina (Black cherry) and the other wild cherries native to your area such as pin cherry and choke cherry whose seeds and leaves are poisonous, and

Sambucus nigra ssp. canadensis (Common elderberry) whose leaves, twigs, roots and unripe fruit are poisonous (but cooked elderberry fruit in jellies and pies is harmless and tasty!)

That being said, there are plenty of good plants to choose from.  If you visit out Native Plant Database and perform a Combination Search, selecting New Jersey/Shrub and the sizes 3-6 ft, 6-12 ft and even 12-36ft,  it will generate a large list to select from.  You can also narrow it further according to specific light and soil conditions as you wish.

What you ultimately plant will be dependant on what is available in the trade and the size of your budget but here are a few of my favorites.

Amelanchier arborea (Common serviceberry) which blooms early in the spring, produces berries that birds (and people) love and has great fall color

Ceanothus herbaceus (Redroot) whose flowers and berries are great for butterflies and birds, but doesn't really color up in the fall

Cornus sericea (Redosier dogwood) whose red twigs bring color to the drab winter landscape, berries support many tupes of fowl and spreading habit will help fill in the hedgerow

Morella pensylvanica (Northern bayberry) whose waxy berries are eaten by many winter birds and used by humans for making traditional candles

Physocarpus opulifolius (Atlantic ninebark) which is tough but attractive with yellow fall colour and red fruit that the birds like, and

Rhus glabra (Smooth sumac) which many people detest because of its suckering habit (maybe just what you need?) but has awesome fall colour and fruit that is not only ornamental but beneficial and high in Vitamin C.  The Chickadees enjoy mine all winter long.

And now for the bad news ... these plants won't harm your cattle, provide wildlife benefits and are ornamental ... but the deer will browse on most of them.
