Who was Dr. Don Egolf? At the southern plant conference there was a discussion between Dr. Margaret Pooler of the National Arboretum and Dr. Mike Dirr of the University of Georgia about Dr. Don Egolf that lead to Mike saying the late Dr. Egolf was the greatest plant breeder of all time. I found this on page 540 in Dr.
Mike Dirr's Manual of Woody Landscape Plants 5th Edition; "Dr. Don Egolf was one of the greatest woody plant breeders that history will ever recognize. He was a scientist, breeder, horticulturist, plantsman, and gardener traits that allowed him to introduce only the best. His plants will withstand the test of time. Like masterpieces of great artists, writers, and musicians, Dr. Egolf's plants stand out from those of mere mortals. As a young assistant professor at Illinois, I met and shook his hand, was able to attend several lectures, and voraciously read his cultivar releases in Baileya and HortScience. All young scientists and aspiring plantsmen should read his detailed descriptions of the new introductions. They leapt from the page into the reader's garden. Don Shadow told me that Dr. Egolf was endowed with the [sic] great eye for quality plants. With Hibiscus, Lagerstroemia, Malus, Pyracantha, and Viburnum “ Dr. Egolf produced magic. Our gardens are richer due to one man's vision and persistence. His woody plant legacy is without parallel." When someone of Dr. Mike Dirr's statue and reputation describes a person like that the words are an understatement. Mike, thanks for reminding us in print, I hope I get to read this statement in the 6th edition.
Nursery Update #34 and #35 have been posted to the web since the last HortMemo. #34 Topics include unsightly eriophyid mites on burning bush, organic and traditional preemergence weed control for container crops, UK Horticulture Club study tour to Oregon, California, Washington, Canada, and Alaska, and the scouting report.

I recently read the Paul Cappiello and Don Shadow book Dogwoods and thanks to the Southern Plant Conference have both signatures in my copy. There is little debate that one of the most beautiful flowering trees in the world is Dogwood.
This book contains a large number of images of Cornus species and cultivars. The descriptions and information on cultivars is incredible but one of my favorites is that "Cornus florida 'Cherokee Princess' was selected by W. C. Higden of Mayfield, KY and introduced in 1959 by Ike Hawkersmith as 'Sno-white'. In 1963 it was registered as 'Cherokee Princess'". Cool! A Kentucky connection. The book is divided into six chapters: 1.) The Family Cornaceae; 2.) The Cornus canadensis Group; 3.) The Cornus alba Group; 4.) The Cornus alternifolia Group; 5.) The Cornus florida Group and
6.) The Cornus mas Group. I was born and raised on eastern Long Island so I enjoyed reading about Jim Cross and Bair Lustgarten, but the book is full of fun trivia; such as Mike Dirr preferring Snicker's Bars to the fruit of Cornus kousa var.
chinensis this discussion lead to numerous taste tests on the Cave Hill Cemetery tour of the 2005 Southern Plant Conference in Louisville. My favorite quote from Mike Dirr on edible fruit of ornamental species is on Cornus mas "although edible, one must be hungry". I started out reading this book in a precursory fashion to write a review, ie. not reading all; then I found myself reading large sections, addicted to the mention of the greats Ernest Wilson, Mike Dirr, Jim Cross, J. C. Raulston, Polly Hill, Gary Handy, Barry Yinger, Kentucky's Higden, Gary Lanham, the now-Illinois Resident John Wachter, as well as, the late Theodore Klein. The book is a hardcover of 224 pages with 261 color photos, 3 black and white illustrations and the USDA Hardiness Zone Map. It fits more to the hand for reading than most of this day and age at 7.38 x 10.38 inches. Timber Press, 2005. For addition book reviews see:

I received the following. “We are in need of a new tree to serve as the Commonwealth Holiday Tree hereon the Capitol grounds in Franfort. The Norway spruce that we have used in years past was struck by lightning and the top is no longer attached to the trunk! We would like to find a Colorado, Engelman, or Oriental spruce of approximately 25'. We believe that we have a contractor with a 90" tree spade to transport this tree but we have, as yet, been unsuccessful in finding a viable candidate.

Nursery Update #32 has been posted to the website below. Topics include More on Asian Ambrosia Beetle, Welcome to Bill Holleran, Tips for Managing Substrate pH, and the Scouting Report. http://www.ca.uky.edu/HLA/Dunwell/KHC/NurseryUpdate32_2005.html
The pruning workshop by Brent Wearren and company was an amazing educational opportunity. Every one of the 60 that attended were handsomely rewarded for their effort to get to Wearren’s rural nursery with hands-on pruning of nursery trees and information on a variety of nursery production related issues. Brent shared his process for getting quality liners to start with that make training the young trees easier and more efficient (more bucks to the grower) . Dividing those attending into groups of 12 and providing an English-Spanish speaking Wearren Nursery employee to train the Spanish speaking in attendance helped each attendee receive direct instruction in pruning techniques. Special thanks to Amy Fulcher, Extension Associate for Nursery Crops for organizing the event and to Brent Wearren for the effort to make it a true learning experience that will lead to quality nursery stock being shipped to landscapers and retailers resulting in more income to those producers that take advantage of what they learned and ultimately a positive impact on their employees and Kentucky’s economy. To Brent the Gene Ryan Award for taking time to share information that benefits the nursery/landscape industry as a whole (the late Gene Ryan readily shared with one and all and assisted me when I first came to the state as a “specialist”).
Kentucky Native Plant Evaluation report: For the first time we have observed a significant population of Spigelia marilandica, Indian Pink, seedlings in one of the UKREC flower beds that have Spigelia. We are pretty excited. The explosive dehiscence manner of seed dispersal had me anticipating we would have lots of seedlings but after almost 10 years these are the first in-the-bed seedlings we have noticed (we may have tilled them out with the winter weeds in the past). It continues to be one of my special favorites of the native plants we are evaluating and more Spigelia plants is always better. On the other hand the spreading nature of Monarda fistulosa, Bergamot, and Pycnanthemum pycnanthemoides, Hoary Mountain-Mint, is starting to cause some concern and certainly more work on controlling their spread. Monarda fistulosa’s susceptibility to powdery mildew and it’s aggressive spreading nature would have resulted in it being eliminated from evaluation and the display bed it is trying to take over if not for it’s wonderful ability to attract butterflies, honey bees, and bumble bees in large numbers. I have moved Cunila origanoides, Dittany, from the full sun field evaluation bed to the full sun display bed this year, it continues to impress me with it’s small rounded habit and long-lasting blue flowers. Our newest planting of Cunila origanoides is in partial shade and is leggy and not as dense as those in full sun.
At the KNLA West Kentucky Chapter meeting we talked about Sudden Oak Death, Emerald Ash Borer, Boring insects in general, Calico scale and pests on the horizon. In the May NMPro e-mail Todd Davis, NMPro editor reported this: New York’s Cornell Univ. identified a single specimen of Sirex noctilio, an Old World woodwasp, in a trap in Fulton, N.Y. This species has devastated up to 80% of pine forests in New Zealand, Australia, South America and South Africa. Federal and state agencies are setting traps trying to find evidence of establishment, according to Cornell. A beneficial nematode has been an effective biocontrol in the Southern Hemisphere.

I went looking for maps of TVA’s Lake Barkley, Kentucky Lake and Land Between the Lakes (LBL) and found the “Native Plant Selector: More than 140 plants native to the Tennessee Valley are featured on this site. It includes photographs and details about height, light preference, bloom time, and more. This list will expand as more native plants become available through commercial markets.” The “guide to plants suitable for landscaping in the Tennessee Valley Region” is there for shoreline owners wanting to plant a native plant landscape as riparian restoration. http://www.tva.gov/river/landandshore/stabilization/plantsearch.htm
Our wildflower garden is small but continues to show that Polemonium reptans, Jacob’s Ladder and Trillium recurvatum, recurved trillium, are great Spring flowering plants with long flowering seasons. We are beginning to find that Phlox divaricata, Blue Phlox, is also a good garden flower. Our wildflower garden is in shade with a moist severely compacted clay soil that is slowly being modified by mixing the hardwood mulch in to the soil.

Dava Hayden checked the pine fines media we are using for a research project and found it to have a pH of 4.2; much below the optimum range of 5.5 - 6.2 we find best for nutrient availability. To correct the low pH Dava plans to add dolomitic limestone. In the process of investigating the pH range needed for most woody plants and how to manage media that have an acid pH Dava compiled information that can be found at http://www.ca.uky.edu/HLA/Dunwell/SoillessSubstratemgt.html
John Hartman included a nice article on Lichens Infesting Tree Trunks and Branches in the Kentucky Pest News #1048, March 7, 2005.

It seems the Theodore Klein Plant Committee knew what they were doing when they named Quecus bicolor, Swamp White Oak as a Theodore Klein Plant Award winner for 2005 . Apparently even President Bush was impressed and signed a bill naming oak as the official U.S. national tree.

I was visiting Bernheim Arboretum and noticed the Magnolia virginiana ‘Henry Hicks’ has brown edges approximately ½ inch on the leaf margins while the Magnolia viginiana var australis looks clean and green. See images at http://www.ca.uky.edu/HLA/Dunwell/Magvirg.html
Thanks to Wallitsch Garden Center and Nursery, 2608 Hikes Lane, Louisville, KY 40218 and Plant Kingdom, 101 Westport Road, Louisville, KY 40207 we now have a good collection of Magnolias including several of the yellows. Keeping in mind they were just planted after overwintering in a greenhouse; ‘Gold Finch’ looks great and is a lemony yellow. We’ll keep an eye on them as they open, see how they perform here in west Kentucky and keep you apprised of our evaluations on-line.
