The Q&A Archives: Potato Vine

Question: I am considering using potato vine to cover a fence. Is it a problem for those of us with allergies?

Answer: Potato vine is a member of the Solanaceae family, cousin to tomatoes and potatoes. The foliage is similar so if you have a reaction to touching the leaves of tomato and potato plants, you'll have the same reaction if you come in contact with the foliage of the potato vine. The flowers produced will have pollen, but not in any great volume. The flowers are pollinated by insects so the pollen doesn't travel too far from the flowers, but it will drop when it is mature. If the vine flowers profusely, you may find a light dusting of pollen on the soil or sidewalk beneath the potato vine.

Hope this information helps you decide whether or not you want to plant potato vine along your fence.
