Ulmus americana, generally known as the American elm or, less commonly, as the white elm or water elm, [a] is a species of elm native to eastern North America. The trees can live for several hundred years.
The Ulmaceae (/ ʌ l ˈ m eɪ s i /) are a family of flowering plants that includes the elms (genus Ulmus), and the zelkovas (genus Zelkova). [3] Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia.
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.

A pollinator garden is a group of plants grown together with the intention of attracting wild pollinators. Pollination is the reproductive process that enables plants to produce seeds. [5] When pollen from the male part of one flower is moved to the female part of another flower of the same species, fertilization occurs.
