Anything more than 120 particles per cubic foot is considered extremely high!!!
One article I read said the combination of heavy rains, colder than average winter and the quick warmup ....
"It's a reproduction explosion right now with pollen everywhere!"
So the net result in the mainland garden is a whole lot of blooming things....like these two apple trees, one of the trees blooms with just a hint of pink, the other stark white.
These iris have a special place in my heart as they were dug from my Mother's garden at the time of her death back in 2002. They have been divided and replanted in my NJ garden (in NJ they bloomed in May at Mother's Day), then down south. They like the woodland clay better than the sand. I am happy to see them each year- a reminder of the green thumb I inherited from another GardenGoddess. :)
