The plants we grow in our gardens are not always beautiful and harmless. The months from August until March can mean sneezing, itchy eyes, a runny nose and extreme fatigue in people who are sensitive to pollen. Others may suffer seasonal asthma, or find that their asthma becomes worse during these months.


The most significant step you can take in planning a low-allergen garden is to choose bird- or insect pollinated plants rather than wind-pollinated ones. Plants pollinated by birds and insects produce only small amounts of pollen. Many native trees and shrubs are pollinated by birds and insects.

 

What to avoid:

  • asteraceae family (daisies, chrysanthemums, calendulas, marigolds)
  • most introduced grasses
  • wattles
  • alder
  • ash
  • birch
  • plantains
  • coprosma
  • elm
  • liquidambar
  • maple
  • white cedar
  • oak
  • olive
  • pines
  • poplar
  • privet
  • walnut
