Russ O'Harra Hosta Society
The Russ O’Harra Hosta Society is an educational society, based in central Iowa, open to all those interested in the genus Hosta. Its purpose is to promote the growing and enjoyment of hostas, including their use in landscape design and the cultivation and development of new cultivars. The goals of the Society are in keeping with those of the American Hosta Society. Our society is named for Russ O'Harra, who was one of the most prominent hosta enthusiasts and hybridizers in the Midwest.

Hercules ​​ by James Goffery and Alex Summers (NR)
​
Building another retaining wall on our hill (to provide space for more hostas, of course!), but the concrete blocks seem heavier than they were last year! And, the legendary Greek strongman Hercules hasn't shown up to help carry them. So, we'll just have to gain inspiration from the H. 'Hercules' that is planted nearby, to complete the task...
H. "Hercules' has broadly ovate, slightly wavy, and slightly corrugated blue-geen leaves with thick substance. It is a 'Sagae' hybrid. Near white flowers appear in midsummer. M. Zilis notes that 'Hercules' and the similar 'Herkules' (by Heinz Klose of Germany) have been mixed in the trade and may often not be distinguished. H 35 W 70

Glenn Herold showed the differences in hosta flowers of various cultivars throughout the season, and Rob Mortko explained the intricacies of hosta tissue culture. Bob Solberg showed variegation trends in hostas produced over the last several decades. Don Rawson tantalized everyone with what's new in the world of hostas. Noah Schwartz described issues in large wholesale grower hosta production, an area unknown to most gardeners, and Mark Zilis provided an informative summary of historical figures in the hosta community.
