Since each of our immune systems has its own way of reacting to intruders like pollen, experts can’t list every plant that will give people the sniffles and sneezes–or tout others as always safe.
Many plants, though, are a common enough source of misery to compile them into a warning list, and other plants are generally regarded as safe enough to recommend to the public.

Carolina cherry laurel (Prunus caroliniana)
Cherry, plum, and peach (Prunus spp.)
Crab apple (Malus spp.)
Crape myrtle (Lagerstroemia indica)
Dogwood (Cornus spp.)
