The Place to Grow

“The Place to Grow” is a community asset of beauty and inspiration. An ongoing project of the Master Gardeners of Benton and Franklin Counties, the garden was developed to demonstrate, test, and teach gardening in its many forms in our unique climate and soils. The garden is supported by Master Gardener volunteers and is funded entirely by donations from individuals, organizations, and local businesses.

Visitors to the Master Gardener Demonstration Garden at 1620 South Union St. in Kennewick, WA, can explore more than two dozen 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 2-acre site.

Have a peaceful stroll, take some pictures, bring a lunch, relax in the shade. Consult and 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.

Upcoming Projects

There are several ongoing projects to maintain and improve the garden for which donations are needed and most gratefully received.

Thank You!
