Plant Identification: How to Spot Allergy Triggers

Each year, hundreds of plants produce pollen. Pollen is primarily associated with allergies among Americans. But of the hundreds of plants that produce pollen, only a handful cause allergic reactions. Spring and fall are typically the worst seasons for allergies. However, pollen can survive through the winter! If you’re trying to pinpoint the cause of your Las Vegas allergies, knowing the top allergy-producing plants helps.

What Plants Cause Allergies?

  • Ragweed
  • Castor Bean
  • Chamomile
  • Daisy
  • Jasmine

 If there is one plant associated with seasonal allergies, it is Ragweed. Ragweed allergies affect one out of five Americans. Ragweed allergies present with itchy eyes, sneezing, and a runny nose. An allergic reaction to Ragweed is attributed to histamines, which the human body releases when it encounters Ragweed.

 Castor bean is another common allergen. Castor bean is quickly-growing and showy, which makes it a popular option for ornamental landscaping. It is a native of the tropics and is, therefore, a commonly used plant in southern regions of the US. Castor bean is an annual, which means it blooms for one season before dying. Although Castor bean is beautiful to look at, it is also toxic. All parts can cause an allergic reaction. An equally attractive plant that’s less likely to cause allergies is Hibiscus. Consider planting this plant instead.

 It surprises many people to learn that Chamomile is a top allergen. And for a good reason! This herb is often associated with its calming and healing properties. However, Chamomile has highly allergenic pollen that can cause congestion and even skin reactions. What most people don’t know is that Chamomile is a close relative of Ragweed. Woolly thyme is an excellent alternative for an attractive and prolific groundcover.

 Daisies are colorful flowers commonly linked to allergies. They are also related to Ragweed and can, therefore, cause allergic reactions in people who suffer from a Ragweed allergy. The leaves, flowers, and pollen of this plant can all trigger allergies.

 Jasmine is perhaps most famous for its intoxicating scent. But for those who suffer from Las Vegas allergies, it is also unfortunately known for its allergy-producing properties. Jasmine’s colorful and fragrant flowers, which are tremendously appealing to many, can also produce allergies in susceptible individuals.
