Taming the Wild Stewartia©
1 Boland-Tim-2019B-Taming-Stewartia Taming the Wild Stewartia© Timothy M. Boland and Todd J. Rounsaville Polly Hill Arboretum, 809 State Road, West Tisbury, Massachusetts 02575, USA [email protected] Keywords: Asexual propagation, native trees, plant collections, seeds, Stewartia SUMMARY The Polly Hill Arboretum (PHA) began working with native stewartia in 1967. Our founder, Polly Hill, was devoted to growing trees from seed. In 2006, the Polly Hill Arboretum was recognized as the Nationally Accredited Collection holder for stewartia. This status has guided our collection development, particularly on focused seed expeditions, which began in 2007. The PHA has been successful growing both species from seed, however, overwintering survival and transplanting of juvenile plants has proved more challenging. New insights into winter storage of seedlings is beginning to shed light on this problem. Experimentation with overwintering rooted cuttings has revealed that plants have preferred temperature and chilling requirements. These new overwintering protocols have thus far yielded positive results. Recent work with tissue culture has also shown promising results with both species. Future work includes grafting superior clones of our native stewartia onto Asiatic species in an effort to overcome the problematic issues of overwintering, transplantability, and better resistance to soil borne pathogens. Our Plant Collections Network (PCN) development plan outlines our next phase work with stewartia over the upcoming several years. The results of this work will be shared in future years as we continue to bring these exceptional small flowering trees into commercial production. 2 INTRODUCTION The commitment to building Polly Hill Arboretum’s (PHA) stewartia collection is based on our founder Polly Hill’s history with the genus and our own desire to encourage the cultivation of these superb small-flowering trees in home gardens. -

Designing Hardwood Tree Plantings for Wildlife Brian J
FNR-213 Hardwood Tree Improvement and Regeneration Center North Central Research Station USDA Forest Service Department of Forestry and Natural Resources Purdue University Designing Hardwood Tree Plantings for Wildlife Brian J. MacGowan, Department of Forestry and Natural Resources, Purdue University Woody plants can be of value to many wildlife species. The species of tree or shrub, or the location, size, and shape of planting can all have an impact on wildlife. The purpose of this paper is to discuss the benefits of trees and shrubs for wildlife and how to design tree and shrub plantings for wildlife. Some of the practices may conflict with other management goals and may have to be modified for individual priorities. Trees and Shrubs for Wildlife The species you select for a tree planting should depend on the growing conditions of the site and the wildlife species that you want to manage. Talk to a professional forester to help you select the tree species best suited for your growing conditions. A professional biologist, such as a Department of Natural Resources District Biologist (www.in.gov/ food source for wildlife (Table 2). Shrubs can be dnr/fishwild/huntguide1/wbiolo.htm), can assist you particularly important because several species of with planning a tree planting for wildlife. wildlife, especially songbirds, prefer to feed or nest There is no specific formula for developing wild- on or near the ground.

Quercus Imbricaria.Indd
Quercus imbricaria (Shingle Oak) Beech Family (Fagaceae) Introduction: Shingle oak is a member of the red oak group with willow-like leaves. It is one of the most handsome of the oaks. Shingle oak has an attractive branching habit and ridged bark, and it casts medium shade in summer. Although fall color may not be outstanding, the shiny, willow-shaped leaves are nonetheless quite attractive through all four seasons. Culture: Shingle oak is an easy oak to grow and adapts to various sites. While it prefers rich, moist, acidic soil and full sun, it is tolerant of drought, urban conditions and slightly alkaline soil. Shingle oak is easy to trans- plant. Because of its very strong wood, this oak is not Botanical Characteristics: subject to storm damage.

IDENTIFYING OAKS: the HYBRID PROBLEM by Richard J
. IDENTIFYING OAKS: THE HYBRID PROBLEM by Richard J. Jensen I Anyone who has spent time trying to identify oaks (Quercus spp.), especially in the for ests of eastern North America, has encountered trees that defy classification into any of the recognized species. Such trees commonly are treated as putative hybrids and often are taken as evidence that species of oaks are not as discrete as species in other groups. On the other hand, some (e.g., Muller, 1941) have argued that many, if not most, putative hybrids are nothing more than stump sprouts or aberrant individuals of a species. Muller (1941) did not deny the existence of hybrids; he was cautioning against an inflated view of the frequency of hybridization as a result of cavalier claims. As he put it (Muller, 1951), 'The freedom of hybridization ascribed to oaks is immensely overrated." While I don't disagree with these sentiments, I do believe that hybrids are a common component of forests throughout North America. Virtually all oak species in North America have been claimed to produce hybrids with one or more related species. Hardin (1975j presented a diagram illustrating hybrid combina tions for the common white oak (Quercus alba L.) and Fig. 1 provides a similar view for northern red oak (Quercus rubra L.). Because these two species have very broad geo graphical ranges and come in contact with a large number of related taxa, there is ample opportunity for hybrid combina- RUB tions to arise naturally. These two examples also reflect the fact that MAR coc instances of hybridization are re stricted to taxa within a section: Quercus section Quercus (the white and chestnut oaks) and ELL IU Quercus section Lobatae (the red and black oaks), respectively. -

Plants with * in column D are thought to be resistant to deer browse. Please note that as the deer population increases and natural food supplies decrease deer may begin to feed off of plants included in this list. Column W ranks the water needs for each species from 1 to 3 with 3 being the highest moisture requirement. Newly installed plants require more water than usual. All plants have specific site requirements so please consult a reliable text for more detailed information about cultural requirements.
