Pines (Pinus sp.) create the Arboretum's second largest woody collection with 200 specimens. We have a small selection of the species that grow world-wide. Our natives, red pine (Pinus resinosa) which is our state tree, and white pine (Pinus strobus) which is one of the most beautiful specimen trees that grow in Minnesota. Pines, even with a variety of disease and insect problems are some of our most versatile evergreens and can be kept at hedge height or in other forms. The many weeping forms of P. strobus are extremely exotic and can be seen in the weeping tree collection. The Scot's pine allee (P. sylvestris) creates the backdrop for the Maze Garden and the shelter for much of our azalea breeding program.
