Maple (Tree)
Description
Maple trees (Acer species) are deciduous trees known for their distinctive palmate lobed leaves and brilliant autumn colors — yellows, oranges, and deep reds. With over 125 species, maples are native to Europe, Asia, North Africa, and North America. Common species include sugar maple (Acer saccharum), which gives us maple syrup, red maple (Acer rubrum), and silver maple (Acer saccharinum). Maples are popular as ornamental shade trees in cities and suburbs for their attractive foliage.
Allergy Symptoms
Maple pollen causes:
- Sneezing and runny or congested nose
- Itchy, watery, red eyes
- Coughing and throat irritation
- Asthma flare-ups and wheezing
Some people with maple allergies experience Oral Allergy Syndrome (OAS), though it’s less common than with birch family trees. Cross-reactivity may occur with other tree pollens.
Typical Pollination Period
Maple trees have a long pollination period because different species bloom at different times:
- Early pollinators: Red maple and silver maple can start releasing pollen in late winter (January or February)
- Peak season: March and April are the most intense months for most species
- Late pollinators: Some species continue into early summer
This staggered timing can mean prolonged exposure for allergy sufferers.
Geographic Distribution
Maple trees grow widely in temperate regions:
- North America: Common throughout the United States and Canada — in forests, along roads, and in urban landscapes
- Europe and Asia: Various native species, often cultivated for their beauty
- Worldwide: Planted as ornamentals, adapting well to diverse climates
Tips for Allergy Sufferers
- Check pollen forecasts and limit time outdoors during high-count days
- Keep windows closed and use HEPA air purifiers
- Shower and change clothes after being outside
- Antihistamines or nasal corticosteroids can help — ask your doctor
- Note that maple season extends over several months due to different species
- For persistent symptoms, consider allergy testing or immunotherapy
