Any sites that will give you all the different pollen types and times of year when they bloom in your area of the country,
I live near Columbia SC?

Consider other pollen sources rather than blooming foliage like residual pollen on the ground or dried flowers. There are plenty of cold weather garden plants like broccoli & my sugar snap peas are still blooming for a fall crop.
