Just as you would want to avoid or reduce seasonal allergens within your home, you should take similar precautions in your garden. If you have a sensitive nose, you may sneeze in response to roses and other strong-fraganced plants such as narcissus, gardenia, daffodil, lilly of the valley, citrus and eucalyptus trees, star jasmine, rosemary and gardenia shrubs.
Wind-pollinated plants such as walnut catkins, scatter their pollens in the air. The plants usually grow in clusters and are more likely to cause allergies, because you cannot help but breath in their pollens. By contrast, more colorful plants and flowers, such as pansies, are less likely to cause allergies because they are pollinated by insects. These flowers and plants produce heavy, sticky pollens that stay with the insect so they do not add the amount of pollen in the air. However their fragrances may act as irritants and trigger reactions in allergic people who have sensitive airways.
Avoid: Amaranthus, ceanothus flowers, juniper, elderberry, rhamnus, roses, star jasmine, gardenias, birch trees, elm and sycamore trees.
