Goodmark Nurseries is a family-owned quality provider of trees, shrubs, evergreens, perennials and grasses. Established in 1985, Goodmark started with 160 acres and has since expanded to 500 acres in two locations: Wonder Lake, IL and Union, IL. Wonder Lake specializes in evergreens, shade trees, and ornamentals. In the summer, they use a 20 acre holding yard to provide plants even when the dig window is closed. South Branch Nurseries consists of 100 acres and specializes in smaller caliper shade trees, evergreens, shrubs, roses, and perennials.
