Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Evergreen hedge non-toxic for horses and goats in Muskogee, OK
Answered by: Barbara Medford

QUESTION:

I live in northeastern Oklahoma. I am trying to find an evergreen hedge, 6-8 ft in height, 4-6 ft spread that is not harmful to horses or goats. Everything that I have found is for Zone 8 or 9.

ANSWER:

We will begin by finding suitable plants for your purpose by going to our Recommended Species, selecting Oklahoma on the map, and Narrow Your Search to first shrubs and then trees. Then, whatever we find, we will check with these various poisonous plant databases to eliminate those you could not use.

It turns out our two favorite evergreen shrubs are still the winners. You are in Zone 7a (average minimum temperature 0 to 5 deg F); both these plants are native to Oklahoma, and will be hardy in your area.
