Many flowers, shrubs, trees, and grasses make very little or even no pollen. And some species produce it only in certain plants. For those, all you need to do is to make sure you have female plants -- the ones that don't make the sneezy, yellow stuff.
This list will help you know what garden plants and flowers to avoid and which are fine, despite your allergies.
