There is a reason why you may be sneezing day in and day out lately and that is the onset of the allergy season. Runny nose, itchy eyes and the general, continual feeling of miserly afflicts everyone who is unlucky enough to have an immune system that can’t pass a dust of pollen without frowning and twitching a little. One of the most common triggers of allergies is plants, meaning that most people are allergic to the plant’s airborne pollen. There are certain plants that cause symptoms of allergy and you better keep them out of the house this season if you do not want to be in bed for the rest of the season.
All the grasses that exist on earth are allergenic in nature and some are more allergenic than the other. Grasses release pollen when they flower and the rye grass flowers during summertime. It is one of those grasses that are doubly allergenic on people with a compromised immune system. Often a common choice for lawns, it is found extensively in meadows, pastures, roadsides, etc.
Ragweed can be well certified as the most allergic plant out there. About 75 percent of the people struggling with pollen allergies are allergic to this plant. What makes matters even worse is that this plant is very common. This plant pollinates in summer and fall and is found along roadsides, riverbanks, in fields, rural areas, etc.
The pigweed comes from a family of weeds and has over 500 species. This weed is aggressive and reproduces by seed. It flowers during spring till fall and can be spotted in landscapes, pasture, on roadsides and other such places.
The pecan tree is one of the most allergenic tress that is native to North America. It is considered to be as allergenic as ragweed. Even though this tree’s pollen does not travel too far, it is large and is therefore allergenic. The pecan tree flowers in spring.
It is not just the plants with big flowers that trigger allergies but also plans with large pollen grains. The oak tree relies on airborne pollination and has small pollen grains that tend to aggravate allergies. The oak flower blooms in spring and can be often found in the woods and plains.
Mulberry trees can be spotted almost anywhere in the tropical regions of the Indian Subcontinent and they are commonly imported to the United States by China in an attempt to allow the silkworm industry to bloom. Mulberries are silkworm’s natural food source and these tress produce flowers as well as fruits. The flowers of the mulberry tree have windborne pollen that is highly allergenic. They flower in spring and can be easily found in woods, river valleys, etc.
The mountain cedar causes some of the most severe forms of allergy symptoms that one may have ever experienced. It blooms at its peak in the spring seasons and is often found in mountainous regions. The pollen grains of this tree are considered to make allergy symptoms worse.
The maple tree produces potent allergens for people with allergies. One of the worst offenders in the family of maple leaf is the ash leaf maple. Pollen allergen is produced only by the male trees and these trees favour rich moist soil and light. They flower and release pollen in early spring. They are most commonly found along streams as well as in the woods.
Elm trees are spread widely in the United States. Elm trees love moist areas and they can therefore, be found close to riverbeds where a lot of other trees would rather not want to be grown. The elm tree produces flower and fruit that release pollen into the air. They flower during the early phase of spring.
