Tourists cover their noses because of the "vomit" smell coming from a pair of 75-year-old trees in the park.

(Dan Tri) - Every year, in October and November, the ginkgo tree haunts many people in the US because it emits a characteristic unpleasant smell.

At the California State Capitol Park (Sacramento, USA) there are two ginkgo trees that make people hold their noses every time they pass by.

According to local media, these two 75-year-old ginkgo trees are emitting a strong, vomit-like stench that permeates the park, causing many residents and visitors to frown.

Not only that, the ripe fruits falling from these two trees also make the walkway slippery, posing a potential danger to passersby.

Ned Friedman, Director of the Arnold Arboretum at Harvard University, wrote an article titled “Stop and smell the ginkgoes,” which states that the outer layer of the ginkgo fruit contains butyric acid, a compound that produces the characteristic smell of “stale butter and vomit.”

Ms. Jennifer Iida - Representative of the Sacramento City Department of General Services - shared: "Ginkgo fruit easily sticks to the soles of shoes, leaving slippery flesh on sidewalks and grass, causing an unpleasant odor and posing a risk of falling."

She also warned that the fruit of this plant contains toxins, and people should wear gloves if they have to come into contact with it.

One of the two “smelly” ginkgo trees is located in a public area, the other is in a construction area. Both are believed to be part of a group of three ginkgo trees planted in 1950 by Governor Goodwin Knight and several state officials.

This year, the stench from the two trees was so bad that authorities had to erect metal fences around them and post warning signs, asking people to stay away from the area.

This phenomenon occurs periodically in the fall, when ginkgo trees bear fruit, usually after they reach maturity between 20 and 30 years of age.

Ms. Iida also added that it is not uncommon to erect fences around ginkgo trees, as the odor and amount of fruit the trees drop varies from year to year.

“We used to have to fence off ginkgo trees in the past, depending on the fruit yield of each season. When the trees bear a lot of fruit, the smell becomes stronger, and more fruit falls, making the surrounding area quickly slippery and difficult to clean,” she shared.
