Founder of the UGA Trial Gardens, Dr Alan Armitage has teamed up with the UGA Center for Continuing Education to offer his first online course, Armitage’s Herbaceous Perennials for the Sun.
Horticulturalists nationwide consider Armitage a leading expert on perennials, and his recommendations for plants in Georgia’s warm, moist climate are taken as gospel by Southern gardeners.
The self-paced course concentrates on Armitage’s selection of 20 perennials for sunny gardens. He will offer insight on how to plant, propagate and care for his favorite perennials. He will also describe each plant’s origin, characteristics, bloom time, flower structure and optimum growing conditions.
“It will be challenging, but we will have fun,” Armitage said.
The course will include audio clips, interactive exercises and end-of-lesson quizzes that provide instant feedback.
It will serve as a crash course on perennials for landscapers and nursery employees, but is also perfect for home gardeners who want to be better informed. Students will learn how to identify the different growing conditions in their landscape, understand which perennials perform best in those conditions and gain the confidence to try new plants.
“This course will appeal to gardeners at all levels, from first-time homeowners to experienced garden center employees,” said Pamela Bracken, department head of special projects and curriculum development at the Georgia Center. “Dr. A. is opinionated and does not pull any punches, and he delivers quality information in a unique and entertaining style.”
Students are given three months to complete the course, and those who do will receive 2.4 hours of continuing education credit.

Taken from the Publication Turfgrass Diseases in Georgia
Symptoms: Large numbers of pinhead-sized fruiting bodies may suddenly appear on grass blades and stems in circular to irregular patches 1 - 30 inches in diameter.
Affected patches of grass do not normally die or turn yellow and signs of the fungi usually disappear within 1 to 2 weeks. These fungi normally reproduce in the same location each year. The fungi are not parasitic, but they may shade the individual grass leaves to the extent that leaves may be weakened by inefficient photosynthesis.
Conditions Favoring Disease: Slime molds are favored by cool temperatures and continuous high humidity. An abundance of thatch favors slime molds by providing food directly in the form of organic matter.
- Remove slime mold by mowing.
- Remove using gardening tool or high pressure stream of water.
