Brick paver walks and patios are specialties. Retaining walls of boulders, treated timber and segmented concrete units are all within the company's scope of activities. Many trees are grown in our 1.5 acre nursery. Improved varieties of crabapple, maple, locust, linden, birch and hawthorn are used in designs. Trees, shrubs, perennials and ground covers arrive in fresh condition on a weekly basis from quality growers all over the Midwest. Plum Line keeps on top of what's hot and what's not in plant popularity. Plants go in and out of fashion much like clothes and furniture.
