Montana is home to many plants that can cause allergies, so it is vital to be aware of which ones you may be allergic to and their appearance to be able to avoid them as much as possible. Some of the most common allergens in Montana include:

Trees

Ash

The Ash tree is a tall, slender tree with smooth, grey bark and leaves arranged in pairs on the stem. The leaves of this tree are oval-shaped, with sharp points at the end, turning yellow or red in autumn before falling off. The flowers of the Ash tree are small and green and grow in clusters.

Cedar

The Cedar tree is a tall, evergreen tree that can grow up to 150 feet tall. It has a slender trunk and branches covered in small, dark green leaves.

Elm

Elm trees are large deciduous trees that can grow up to 100 feet tall. They have a broad, spreading canopy and their branches droop toward the ground. The leaves of an Elm tree are oblong in shape and have a serrated edge. The bark is dark brown or gray and is rough to the touch.

Maple

A Maple tree is typically a tall, deciduous tree that has smooth, gray bark and large leaves in a lobed shape. The leaves are usually red or yellow in the fall.

Oak

An Oak tree is a deciduous tree that can grow incredibly large, up to 100 feet tall. They have thick, sturdy trunks and branches; their leaves are dark green and lobed.

Grasses

Bermuda

The Bermuda grass is a type of turfgrass common in warm climates. It has a light green color and a dense, compact growth habit.

Johnson

The Johnson grass is a tall, slender plant that can grow up to 6 feet tall. It has long, narrow leaves that are green in color and have a white or light-colored stripe running down the center. The flowers of Johnson grass are small and yellow in color, and they grow in clusters at the top of the plant.

Orchard

The Orchid grass is a flowering plant native to many regions. This plant has long, slender leaves, often variegated with different colors. The flowers of Orchid grass are small and delicate, and they typically bloom in the summertime.

Ryegrass

Ryegrass looks like a grassy plant that is usually green in color. It is a common grass type found in many lawns and gardens.

Timothy

The Timothy grass has a short, thick stem and long, narrow leaves. The flowers are small and brown and grow in clusters at the top of the plant.

Weeds

Cocklebur

The Cocklebur weed looks like a small, round, green plant with prickly leaves. The flowers are small and white, turning into brown seed pods containing many seeds. This weed spreads quickly because the seeds cling to clothing and animals.

Dandelion

A Dandelion weed is a small, yellow flower that grows in the wild. The flower’s stem is thin and frail, and the leaves are long and jagged. The flower itself is small and delicate, with petals that are soft to the touch.

Lamb’s Quarters

The Lamb’s quarters weed is commonly found in many gardens and yards. It has a distinctive shape, with large leaves that are often lobed or serrated. The plant’s flowers are small and white and grow in clusters.

Plantain

The Plantain weed is a short, broad-leaved plant. It has small white flowers that grow in clusters, and its leaves are dark green and glossy.


All of these above plants release pollen to fertilize other plants of the same species. Pollen is carried by insects or by the wind from one plant to another, where it will eventually encounter the female reproductive organs of the plant. This process is essential for the survival and continuation of the species as it allows for genetic diversity and ensures that new generations of plants can grow and thrive. While pollen can be a nuisance for those who suffer from allergies, we can appreciate its importance in the natural world.

When Is Allergy Season In Montana?

Allergy season in Montana typically begins in early May and lasts through late June, sometimes until October. However, allergy season can start earlier or last longer, depending on the local weather conditions and different plants.

The most common allergens during this time are tree pollen, grass pollen, and weed pollen. In Montana, the pollen season for grasses typically begins in mid-May and ends in late June or early July. For weeds, the pollen season usually starts in early May and goes until late September.

As for trees, it depends on the species! The Ash tree releases pollen in early spring. The Birch tree releases pollen in late spring/early summer. The Cedar tree releases pollen in mid to late summer. The Elm tree releases pollen in early fall. The Maple tree releases pollen in mid-fall. The Oak tree releases pollen during September and October, and the Poplar tree releases its pollen in early to mid-spring.

Pollen counts are usually highest in the morning and on warmer days with little wind. However, as we’ve seen, it depends on the specific type of plant as to when their peak season for releasing pollen is.

Allergy Symptoms In Montana

Allergies
Symptoms of hay fever include a runny nose, sneezing, itchy eyes, and congestion.

When pollen or other particles from plants enter our noses, they can trigger an allergic reaction. Our bodies produce histamines in response to these particles, which leads to symptoms like:

  • Sneezing
  • Watery eyes
  • Runny nose
  • Fatigue
  • Rash
  • Itchiness

These reactions are more common in the springtime when pollen levels are higher.

One of the most common allergy symptoms in Montana is sneezing. Various things can cause sneezing, but it is usually caused by pollen in the air. Another common symptom of allergies is itchiness. Finally, other common symptoms during allergy season are watery eyes and fatigue. Watery eyes can happen when your eyes encounter allergens like pollen and start to produce more tears than usual to wash the allergens away.

It’s important to note that everyone can react to allergens differently. Most people have mild symptoms, but for others, these symptoms can be more severe or even life-changing.

Best Allergy Treatments In Montana

If you suffer from allergies, there are a few things you can do to help ease your symptoms.

First, try to stay indoors as much as possible when pollen levels are high. If you must go outside, wear a dust mask, face covering, or sunglasses to protect your face from pollen.

You should also shower and change your clothes when you come back indoors to remove any pollen clinging to your skin or hair.

Purchasing and using over-the-counter antihistamines and steroid creams can also help reduce symptoms.

If your symptoms are severe or worsening instead of getting better, it is worth considering seeing an allergist or your doctor for further evaluation and treatment options. Allergists can provide you with medication to help relieve your symptoms and advise how to best manage your allergies during every allergy season.

It can be essential to seek treatment during allergy season, as allergies can interfere with your quality of life. Allergies can make breathing, sleeping, or even enjoying being outdoors harder. If your allergies are severe, they may even lead to further health problems if left untreated. For example, if you have seasonal allergies and don’t treat them, you may be at risk for developing sinus infections or bronchitis. These conditions can be much more severe than the allergies themselves, so it’s important to nip them in the bud by seeking treatment early on.

Treating your allergies during allergy season can also help prevent them from worsening over time. If you don’t treat your allergies now, they may become more severe in the future and more challenging to manage.

Why Humans Experience Allergies

When these plants release pollen into the air, this causes an allergic reaction in some people. The immune system mistakes the pollen for a harmful substance and releases chemicals called histamines to fight it off.

There are a few reasons why humans suffer from allergies. One reason is that our immune system may overreact to certain substances, such as pollen or pet dander. When we encounter these substances, our immune system releases something called histamines, which can cause known symptoms like sneezing, itching, rash, and watery eyes.

Another reason for allergies may be that we are exposed to more allergens than in the past. For example, more people are living in cities now than ever before. This means more traffic and air pollution, which can exacerbate allergies. Also, homes are better sealed against the outside world, so we are less likely to build up immunity to common allergens like dust mites.

Finally, some experts believe that the hygiene hypothesis may affect allergies. The hygiene hypothesis states that exposure to dirt and bacteria early in life helps to build immunity and prevent allergies later on. However, because we now live in much cleaner environments than in the past, we may not get this vital exposure early enough.

Another factor that can contribute to more allergies is climate change. Warmer weather means longer allergy seasons and more pollen in the air for more extended periods. All of these factors can contribute to the growing number of allergy sufferers in Montana.

Outlook For Allergies In Montana

Allergies can make the sufferer feel that their symptoms will never go away and ruin their quality of life. But fortunately, they are usually only temporary and will eventually go away on their own. For most allergy sufferers, symptoms are typically mild and can be treated at home or by your local doctor.

Allergy season will ultimately end, and you’ll be able to breathe easily and enjoy your time outdoors again as the weather cools down. In the meantime, there are many things that you can do to minimize your symptoms and make the best of the situation. So find the best options that work for you and your allergies.
