allergy patient questionnaire

The three most allergenic grasses in Jacksonville and North Florida are: Bahia, Bermuda and Johnson grass. Most folks have heard of the first two, but what the heck is Johnson grass???

According the the University of Florida, it is an invasive grass introduced from the Mediterranean. It tends to grow in clumps and can reach 8 feet in height! And yes..it’s very allergenic. Here’s a picture of Johnson grass below—more information an be found at http://plants.ifas.ufl.edu/node/429.

You’ll most likely spot Johnson grass growing as tall clumping grass along the edge of wooded areas and in fields. See if you can spot any Johnson on your next morning commute.
