   CURRENT PROJECTS

Solutions to Invasive Ornamental Shrubs
Berberis thunbergii
(Japanese barberry) and Euonymus alata (burning bush) are two valuable landscape shrubs that represent millions of dollars annually through the sale of horticulturally useful cultivars. Unfortunately, both species can be invasive. We are evaluating the invasive potential of horticultural cultivars to ascertain if they pose a similar invasive threat to that posed by wild forms of each plant. We are also working to create sterile forms of each species and to determine the origin of invasive populations using genetic fingerprinting technology. We are also working with Buddleja. Our primary goal with this genus is to develop dwarf or compact forms that are sterile and maintain zone 5 cold hardiness.

Development of Horticultural Internet Resources
The World Wide Web has become an excellent educational tool, providing students and the public easy access to information presented in innovative and unique ways. I have created a web application called the "UConn Plant Database" that presents pictures and information about more than 500 trees, shrubs and vines that are grown in U.S.D.A hardiness zone 6 or colder. "Virtual Campus Plant Walks" accompany this collection of plant information, and allow students to review outdoor campus plant walks over the Internet. The "Plant Selector" provides users with a tool to choose plants that meet ornamental characteristics and landscape situations they specify in an internet browser form.

Ornamental Plant Breeding
I have introduced 11 cold hardy rhododendron cultivars that are well adapted to the climate of New England and similar regions. The rhododendron breeding program was started in 1960 by Dr. Gustav Mehlquist with the goal of developing durable, cold-hardy rhododendrons with new flower colors, improved growth habits and disease and insect resistance. Introduced in 1999, the "Raise the Roof" series of rhododendrons were all given basketball-related names to celebrate the women’s and men’s NCAA basketball championships. Although unusual, the names ‘Buzzer Beater’, ‘Hoopla’, ‘Huskymania’, ‘March Madness’, ‘Slam Dunk’, and ‘Tip Off’ have been well received and are proving to be popular. Other rhododendron introductions are ‘Carole Ray’, ‘Connecticut Yankee’, ‘Firestorm’, ‘White Peter’, and ‘Wojnar’s Purple’. Halesia tetraptera 'UConn Wedding Bells' is a multistemmed selection of Carolina silver bell that blooms prolifically, with flowers that open wider than is typical for the genus. Ruby Ribbons switch grass (Panicum virgatum 'RR1') is a recent patented and trademarked ornamental grass that I bred. It has blue-green base foliage that turns a deep wine-red color weeks earlier than other red switch grasses. It is being launched for wholesale production by Ball Horticultural Co.

Native Shrub Improvement Program
Shrub species native to the northeastern United States have been overlooked as ornamental landscape plants. There is growing interest in the use of native species as people look to replace invasive exotic species and cultivate landscapes that blend harmoniously with surrounding natural vegetation. My program is currently focused on the genera Aronia (Photinia), Myrica (Morella) and Physocarpus with the objective of evaluating, selecting and breeding superior genotypes for landscape use.
