The Place to Grow

“The place to grow” is a community asset of beauty and inspiration…it is an ongoing project of the Master Gardener Foundation of Benton and Franklin counties. Developed to demonstrate, test, learn and enjoy gardening in its many forms in our unique climate and soils, it is supported by Master Gardener volunteers and is funded entirely by donations from individuals, organizations, and local businesses.

The Demonstration Garden is free and open to the public daily from dawn to dusk. Its paved pathways are disabled-accessible. We invite you to explore the more than 25 distinctive and ever-changing theme gardens. The gardens currently feature over 50 trees, 800 roses, 100 shrubs and even a children’s garden at the serene two acre site. Have a peaceful stroll, take some pictures, bring a lunch, relax in the shade…visit with the Master Gardeners!

The Goals of the Demonstration Garden

  • Demonstrate various types of locally suitable trees, shrubs, and other plants and their uses in home landscapes and gardens.
  • Raise public awareness of sound gardening practices through teaching, testing and demonstration.
  • Provide a place of beauty and tranquility for garden visitors of all ages.

Thank You!

The Demonstration Garden is the effort of volunteers and the WSU Master Gardeners Foundation Steering Committee. Since breaking ground on August 6, 1999, the Demonstration Garden has enjoyed donations of about 64,000 volunteer hours and the financial donations of citizens, foundations, and the business community.

If you would like to memorialize a loved one, celebrate a special event in your life or make a gratefully appreciated donation to support the garden, please see our Donate to the Demo Garden brochure.
