Clinton's Bickelhaupt Arboretum and its $1.8 million of financial assets were presented to Eastern Iowa Community Colleges (EICC), becoming a part of EICC's Clinton Community College (CCC).
The Bickelhaupt Arboretum sits on 14 acres of land and features select-labeled trees, shrubs, ground covers, perennials and annuals.
The $1.8 million in financial assets will be donated to the Paul B. Sharar Foundation, which will fund the arboretum.
Officials said talks of the donation began in March 2014. It will offer Clinton's Community College students greater opportunities when learning about horticulture.
"We are looking at adding some additional programs and we will look at some additional services," said Karen Vickers, president of Clinton Community College.
Francie Hill, the daughter of the arboretum's founders Bob and Francis Bickelhaupt, said she decided to donate the family heirloom because she believed the community college would use it to benefit the community.
"It is absolutely amazing to give something that was so very important to my parents," Hill said after the press conference on Tuesday.
"I know my mom and dad have passed on, but this is exactly what they would have wanted," Hill added.
The arboretum was developed in 1970 by Bob and Frances Bickelhaupt in response to the Dutch Elm Disease which killed the majority of large trees in Clinton.
Officials with the Quad Cities Visitors Bureau said the Bickelhaupt Arboretum is the closest arboretum to the Quad Cities.
