The Knox Creek Farm arboretum is WISCONSIN’S MOST NORTHERLY ARBORETUM, dedicated to increasing the love and knowledge of trees, history and the natural world. It is a place for the scientific study and public display of various species of trees and shrubs.

The KCF Arboretum is a living museum located in the heart of northern Wisconsin’s coldest area, zone 3, which makes acquiring and growing new species a very challenging activity. The Arboretum has many rare and unusual trees and shrubs for the area. The Arboretum features over 265 species and

cultivars of trees and shrubs native to North America, as well as horticultural varieties native to other parts of the world. The Arboretum is particularly known for its dwarf conifer collection.

The Rhododendron Collection encompasses a grouping of rhododendrons, azaleas and related plants under a canopy of mature Norway pines. While the bulk of flowering occurs in May and June, the sheltering tree canopy makes this area a favorite destination for peaceful walks throughout the summer and fall.

The Arboretum acquires plants and places them into gardens and themed plant collections. We collect and display a diversity of plants for evaluation, enjoyment and educational purposes, in order to convey sustainable plant choices recommended for our region. By sustainable, we mean plants that are: adapted to our soils and climatic, extremes, e.g. are winter hardy, free from chronic diseases and significant pests and are non-invasive of natural areas.
