Mt. Cuba Announces Ragweed Trial

(Hockessin, Delaware—April 1, 2024)— Mt. Cuba Center in Hockessin, Delaware is pleased to announce its latest trial garden evaluation on Ambrosia, commonly known as ragweed. Special focus will be given to Ambrosia artemisiifolia, or common ragweed, which is distributed throughout North America and considered by many as the bane of hay fever season.

Rather than counting pollinator visits, our Trial Garden staff and volunteers will be taking a different approach for this wind-pollinated plant. Instead, they will measure the distance the pollen can travel to trigger sneezing. We are currently seeking volunteers to help with this important research, please check our website to apply.

Ambrosia, also known as ragweed, is an underutilized genus that is surprisingly absent from the world of horticulture. Ragweeds possess an understated beauty and are unique in their ability to stimulate the senses and leave gardeners breathless. We hope that through our three-year evaluation we can elevate the genus Ambrosia and inspire others to add a ragweed to their home landscapes.”

Guests visiting the garden during peak pollen production will be encouraged to visit the ragweed planting for a truly interactive experience. Tissues and allergy medications will be available for purchase at the front desk.


Happy April Fool’s Day! It seems that perhaps Linnaeus also had a sense of humor naming ragweed Ambrosia (the food of the gods), or maybe he just didn’t have allergies! Check out our real Trial Garden Research here.
