Demonstration Gardens

The Horticulture Program, with assistance from Master Gardeners, maintains three demonstration gardens in Harvard Gulch Park.  These gardens serve as a means of education and outreach for the local community, while also functioning as a testing ground to see how well plants perform.

Plant Select® Garden

Plant SelectThis demonstration garden was designed and installed in front of the CSU Extension office in 2007.  The design was created by Superior Landscape Design, Inc.  Plant Select® is a plant selection program that is a collaboration among CSU, Denver Botanic Gardens, and the regional horticulture industry.  The mission of Plant Select® is to seek out, identify, and distribute the best plants for landscapes and gardens from the intermountain region to the high plains.  For more information, visit:

Vegetable Garden

Vegetable GardenLocated at the corner of Iliff Avenue and Emerson Street, the Vegetable Garden was established in 2011 in response to the growing local food movement.  Each year, plants are started from seed in the Denver City Greenhouses, and then transplanted at the end of May.  This garden has been a successful partnership with Denver Parks & Recreation and Grow Local Colorado.  In total, over 2,000 pounds of fresh produce from this garden has been donated to the St. Francis Homeless Shelter in Denver.  For more information, visit:

Native Plant Garden & CO State Children’s Home Memorial

This demonstration and memorial garden was designed and installed in front of the CSU Extension office in 2013.  The design was created by Alexis Alvey, Denver Horticulture Extension Agent.  The garden is a tribute to the unique cultural and natural history of the area.  All featured plants are indigenous to the state of Colorado and are adapted to its harsh climate.   The garden also serves as a memorial to the 17,000 children who lived and thrived at the CO State Children’s Home which operated in Harvard Gulch Park between 1895 and 1971.
