Shrubs for Kansas: Viburnum Primary Investigators: Dr. Cheryl Boyer, Mr. Joshua Pool, Dr. Jason Griffin The climates in Kansas can be quite variable and each has their own unique set of challenges. As we work to develop lists of tried and true landscape plants it is also helpful to evaluate new (or new to many) plants across the state. In this, the first of many shrub trials, we have chosen the genus Viburnum to kick off the project. We hope that species survival and detailed stress analysis will help us determine which characteristics of ornamental plants can predict survivability and growth across the state. This study, installed in 7 trial sites across the state, was planted in the Fall of 2012 with evaluation continuing for at least 2 years. Some counties will have demonstration plots made available to the public. Replicated trial sites can be found here:
  • John C. Pair Horticultural Research Station, Haysville
  • K-State Research and Extension Center for Horticultural Crops, Olathe
  • Parsons Arboretum, Parsons
  • Tuttle Forestry Research Center, Manhattan
  • North West Agricultural Research Center, Colby
  • Prairie Wind Aquatics, Garden City
  • Central Kansas District Extension Master Gardener Display Garden, Salina
Demonstration trial sites can be found here:
  • Agricultural Research Center, Hays
  • Sedgwick County Extension Office, Wichita
  • Douglas County Extension Office, Lawrence
  • Kansas State University Gardens, Manhattan

We will gather data on the following plant characteristics:
  • Survivability
  • Growth
  • Date of first spring flower
  • Date of last flower
  • Flower fragrance
  • Flower and fruit abundance
  • Fruit color and prevalence
  • Color of new leaves and timing of bud break
  • Evergreen, semi-evergreen, deciduous status
  • Fall color description
  • Date of first fall color
  • Date of dormancy
  • Photographs
  • Diseases/Pests
