It's not a pleasant smell at all.
"It's not very appealing whatsoever," says Mike Perros, with Stifel, Nicolaus & Co.
"Almost like a sulphur type of smell. It's not a good smell," says Julie Nelson with Maple Tree Gallery.
However, it's what people are dealing with right now in downtown Danville, caused by these ginkgo trees.
"This time of year the female trees bear fruit and they drop to the ground and it has an odor which is not very pleasant," says Julie Nelson.
The only thing is, these trees are supposed to be male trees.
"Now all of a sudden this year they're bearing fruit when everyone thought they were male trees," says Mike Perros.
City manager Paul Stansbury says the trees have been in place since the early '90's'.
"They had a female root system with a male system graphted over it," says Paul Stansbury.
Which, Stansbury says, with stress over time can cause them to produce fruit.
"With the summers we've had, the drought and the ice storms we've had in the last few years, we've started to see some of these trees bloom out and produce the fruit," says Paul Stansbury.
That went from a couple trees a few years ago, to now eight, producing a smell and problem for some business owners on Main Street.
"It's a bit of a nuisance, yes," says Mike Perros.
In the meantime, the city manager says he's trying to get more manpower to the Main Street area while the trees are dropping fruit to help with this problem. The city manager says there is a chemical that they can apply to the trees in the spring that might prevent them from blooming or producing fruit. They are looking into that option and others so they won't have to remove these trees.
