SMART LANDSCAPING WITH ALLERGY FREE PLANTS

Seasonal allergies or “allergic rhinitis” is most often due to pollen from the plants and trees gracing your property or neighborhood. 

Here are examples of allergenic plants from the least (1) to the most allergenic (10).  The information was obtained from Thomas Leo Ogren's book, The Allergy Fighting Garden.  I highly recommend purchasing a copy if you are interested in a more comprehensive listing.

 Acer rubrum 'Autumn Glory' is an allergy free shade tree with amazing fall color.  It's a native cultivar of the Northeast United States and extremely tolerant of many soil conditions.
