Is pollen from flowers the leading cause of allergies?
Ironically, some of the most feared plants—the brightly flowering varieties—are the least likely to trigger allergic symptoms. Pollen from roses and many other fragrant, colorful flowers tends to be heavy, waxy and sticky, making it less likely to become airborne. These pollens are not spread by the wind. Instead, insects transport pollen from flower to flower. Allergies to these plants are very uncommon (even among florists and gardeners who are exposed to them frequently).
