Organic in The Garden – Low Allergy Annuals

Low Allergy Annuals

Annuals are mainly grown for their flowers as garden color or cut flowers. Pollen from flowers is a major allergen so if you suffer from an allergy like hay fever it is wise to consider looking for low or no allergen flowering plants for your garden.

I have suffered from hay fever since I was a kid. As a country boy I was introduced to the allergy while carting hay on my uncles property. Over the years I have come to know the types of plants that cause the allergy to flare up as well as those that have no effect on it at all. I have also noticed some heavily pollinated flowers that for one reason or another do not affect my hay fever while others that I would expect to be low allergen have made the condition worse.

Despite my hay fever I established a career in the Horticultural industry working around both high and low allergen flowers.

Some of the flowers I have found to be low allergen include:

Opium Poppy (Papaver somniferum)

Poppies like a soil that is highly fertile and free draining with a full sun aspect. Organic mulches can be added to the soil with compost, vermicast and animal manures to increase soil fertility. Poppies are traditionally Summer flowering though will still flower into Autumn. The foliage is a bluey-green colour with flowers in shades of red, pink purple and white. Single or double flowered varieties can be solid or variegated. Poppies often grow to greater than 1 metre in height.

Begonias work well as border plants, in beds or in pots. Begonias are well adapted to growing indoors, their low allergen grouping makes them ideal for this environment. The season of interest for Begonias is Summer.
