Gardens of the Minnesota Arboretum:

Annual Garden

This formal garden is centered around an elegant English Fountain and each year is planted with different colors and textures. Each spring, the gardeners at the Arboretum plant between 25,000 and 30,000 annuals in this exhibit.

Dahlia Trial Garden

Every year the Minnesota Dahlia Society brings new varieties of dahlias to the Arboretum trial garden, where they can be planted and monitored for various traits and guidelines such as growth rate, disease resistance, and quality of the flower. This garden truly shines during the late summer months when the dahlias are in full bloom.

Daylily & Chrysanthemum Walk

Late blooming Chrysanthemums are an excellent addition to any garden as these perennials are available in a wide range of flowers and colors, and they are still blooming when very few other plants are. Guests to this walk in the Arboretum will see over 81 different varieties of chrysanthemums on display.

Dwarf Conifer Collection & Waterfall Garden

Gardeners in the Upper Midwest region of the country will find dwarf conifers to be among the most exotic plants in their garden. This collection covers a wide variety of plants ranging from the creeping juniper that is only a couple of inches high, to the larger fifteen foot high dwarf spruce.

This collection of wildflowers and hardy ferns extends from the Azalea Garden, all the way into the woods to the hidden pond. Those who venture along the walk will see approximately 20 different fern varieties and 9 different types of wildflowers along the path.

Hedge Collection

Hedge gardens are a very versatile and practical way of using plants, and a great many homes across the country use hedges for various reasons.
