This stuff is my kryptonite. I am so allergic to this stuff that I get contact dermatitis when I brush against the seed heads. It is like Poison Ivy except it shows up in about 10 minutes.
Because this is a tall grass, up to five feet tall, walking through it puts clouds of pollen right at face level.
The next ten days will have me mostly inside. If I go outside I will carry antihistamine eye-drops and will probably dose myself with diphenhydramine before walking around outside.
