Cottonwood trees produce male and female parts on separate trees. In spring, female trees produce tiny, red blooms that are followed by masses of seeds with a cottony covering. The cotton-covered seeds create a significant litter problem. (2)
It was this litter and despite their shade giving qualities that the City Council in 1864 declared cottonwood trees to be a nuisance. This led to a citywide effort to remove them from the city. (3)
