OLATHE, Kan. — The hottest, newest plants will be on view and classes in air-conditioned comfort will be available at the K-State Olathe Horticulture Research and Extension Center’s Field Day, Saturday, July 25, from 8 a.m. – 2 p.m. It's a chance to peek behind the scenes, talk with the experts and learn about the latest varieties and methods for achieving growing success. Herb recipes and high-tunnel strawberry research will be showcased at this year’s event.

Admission is $5 per person, which includes cold bottled water, seminars, classes and demonstrations. K-State specialists develop their lists of recommended grasses, flowers and vegetable varieties through research conducted in Olathe to determine what grows best in our Kansas City landscapes. 

What you'll see

The Center conducts research in flowers and vegetables. Visitors can speak with university professors heading up the research and Johnson County Extension Master Gardener volunteers.

Flower Highlights

  • Annual flower trials - Companies from around the world submit their newest developments. The trials show which flowers withstand the Kansas City climate. Not all varieties are created equal. Check out the container plantings as some flowers are only meant for use in pots.

  • New annual introductions – ‘Monarch Promise’ Milkweed is an ornamental with variegated foliage that enhances butterfly habitat. New to the market is Echibeckias, a cross between Echinacea (Coneflower) and Rudbeckia (Black-Eyed Susan) — two prairie natives which make it appealing for Kansas gardeners.

  • Cut your own flower bouquet area – a cutting garden is a fun way to bring the garden inside. Learn which plants work for providing summer enjoyment.

  • Impatiens Downy Mildew – this disease is continuing its spread into Kansas City. See what’s new in impatiens to help fight this disease.

  • Year of the Coleus – come see 21 varieties, including three  terra-cotta colored cultivars, and the Under the Sea® varieties with wildly serrated leaves. Foliage is hot.

A soil test determines the nutrients in the soil. It is important to know the nutrient levels to grow healthy plants. Go to Soil Testing in Johnson County, Kansas to learn how to take a soil sample.  At least 2 cups of dry soil are needed for a proper test.
