Plants provide us with food, fiber, shade from the sun and excite our senses of taste, smell, touch and sight.Pollen is essential for the reproduction of flowering plants.Unfortunately, many people suffer from allergies triggered by pollen.Not all flowering plants produce pollen that may cause allergies. Plants with showy flowers usually have pollen that is waxy or dense which is carried by insects for pollination.Plants that produce small wind-blown pollen grains are the usual culprits for allergies.In the spring, pollen from oak and pine trees are the most common allergens.In the late spring and summer, grasses like ryegrass and in the fall ragweed.Goldenrod was previously blamed for causing allergies, but studies show it was not an allergen. Goldenrod is now widely used in the floral industry.
