The diverse species mix originally planted at Lindberg Park in 2000 was lost due to the invasion of aggressive plant species such as Canada thistle, tall goldenrod and New England aster. The Park District’s Greening Advisory Committee worked with the Park District to oversee plans to restore the plantings in the Trial Gardens to recreate the desired plant diversity. The first phase of plantings wer completed in June 2012. Successive phasing continues yearly as well as specialized, ongoing maintenance of this unique area.
