*Allergy causing plants. Alder pollen is the the worst. Only the (m) male plants of dioecious trees and shrubs are of concern. The highly visible yellow pollen from Douglas Fir, hemlock, pine, true firs, and spruce, rarely triggers allergies. Plants with showy flowers (most fruit-bearing trees) because they depend on insects for pollination, not the wind, rarely create an allergic response.
