Successful implementation requires considerable labor, facilities, and monetary resources for evaluation of large numbers of taxa over several years to ensure that plants are well adapted to the region of interest. Research and development funds, dedicated facilities, and cooperator commitment to trialing programs can be limiting during the early years of the programs. Involvement in plant trialing programs allows students to be exposed to plot layout planning, statistical design, plant maintenance, data collection and analysis, and professional communication of trial results. Construction of facilities for conducting plant trials, growing plants for use in trials, trial installation, and maintenance of plants all provide practical hands-on horticultural training. Replicated plant trials provide the latest information on regionally adapted taxa...

In 2000, over 20 theme gardens now occupy 18 acres. The garden is computer mapped and an accessioning system is in place. Theme garden developments include daylilies, herbs, a rock garden, a xeriscape, plants for shade, wetland, and bog conditions, a line of vines, an Asian Valley, conifers and hollies, and numerous gardens that trial and display herbaceous perennials. Recent developments include a children's garden and, the biggest project to date, an 8-acre SFA Ruby Mize Azalea garden, with a grand opening in Apr. 2000. Theme gardens are utilized to display collections. Significant assemblages include Rhododendron (400 cultivars and selections), Acer (168 cultivars), Camellia (210 cultivars), Loropetalum (18 taxa), Cephalotaxus (43 taxa), Magnolia (47 taxa), Abelia (37 taxa), Ilex (73 taxa), and others.

HISTORY OF THE PNPC The Pineywoods Native Plant Center (PNPC), formerly known locally as the Tucker property, is a 40-acre mix of uplands, mesic mid-slopes, and wet creek bottomland that lies on the northern edge of Stephen F. Austin State University (SFA) right in the center of Nacogdoches, the "oldest town in Texas." Drs. Dave Creech and James Kroll first met early one morning in April 1998 in the SFA Mast Arboretum, a meeting called by Dr. Kroll. After thirty minutes, a goal was in place. The deal was sealed with a handshake and the first steps were made to broach the subject with SF A's administration and receive a sanction. The SFA Board of Regents approved the idea in February 1999. Technically, the PNPC is a joint project of the SFA Mast Arboretum and SF A's Forest Resources Institute, a collaboration helping both organizations fulfill their conservation and educational missions. Drs. Kroll and Creech serve as founders and for the last decade have served as co-directors of this unique center for native plant education. The mission of the PNPC is to promote education about the conservation and use of native plants of the southern forest. The PNPC was dedicated at SFA in an outdoor gala event March 27, 1999. A grand opening followed on April 8, 2000, a very high publicity event that featured the dedication of the Lady Bird Johnson Wildflower Demonstration Garden (LBJWDG) by Lady Bird Johnson herself. With the generous help of Ellen Temple, the PNPC secured the services of Darrel Morrison, noted

Since 1985 the Gardens have grown from a small 1/4 acre patch on the south side of the SFA Agriculture building to 128 acres of on-campus property. The gardens boast an amazing diversity of plant life that has been accumulated through a network of friends, plant enthusiasts, nurserymen, and horticulture and arboreta research colleagues in the USA. There are four main garden areas-the SFA Mast Arboretum, the Ruby M. Mize Azalea Garden, the Pineywoods Native Plant Center and the Gayla Mize Garden. What makes SFA Gardens special is plants, people and plans! The Mast Arboretum is a 10-acre garden along LaNana Creek at Stephen F. Austin State University, Nacogdoches, Texas. The Arboretum began in 1985 as a project of the first Landscape Plant Materials class taught by Dr. Dave Creech. Over the years, this garden has expanded into one of the most diverse collections of plants in the South. The Mast Arboretum is dedicated to acquiring, testing, introducing and promoting new plants for the landscape and nursery industry in the southern USA. The SFA Pineywoods Native Plant Center (PNPC) is a 42-acre garden on the north end of the SFA campus dedicated in 2000. It's a unique mixture of uplands, mesic mid-slopes, and wet creek bottoms. The Tucker House serves as the central feature of the property, which is surrounded by native forest and gardens that celebrate the wonderful diversity of native plants in the region. Since 1996, endangered plant research has been a core research practice. We are in a capital campaign to build a Conservation Education Center at the PNPC, which will support our environmental education programs on-site, in all weathers and in a building that exhibits green building practices and environmental conservation practices. The eight-acre Ruby M. Mize Azalea Garden is the result of a partnership of the SFA horticulture program and members of the Nacogdoches community, nurtured by several local families who believe beautiful gardens are an important part of community vitality and the education process. This garden was developed as a project of the SFA Mast Arboretum, and was begun in response to the wishes of Nacogdoches residents Mr. and Mrs. A. T. Mast, Jr. that the university beautifies its eastern entrance. It wasn't long until SFA alumna Dorothy Wisely lent a helping hand with an endowment for the garden. Construction began in an overgrown loblolly pine forest in the winter of 1997. Dedicated in April 2000, most of the plantings were completed 2 years later. Today, the garden contains 46 planting beds, 1.25 miles of universally accessible trails, and 50 benches. The garden features over 550 varieties of Rhododendron, 100 varieties of Camellia, two hundred plus Hydrangea varieties, and a wealth of other unique collections. After a decade in existence, the Ruby M. Mize Azalea Garden is a highlight of the annual Nacogdoches Azalea Trail. Special events each March include guided tours during azalea season, an annual Azalea Symposium, and a Little Princess Tea Party. The Gayla Mize Garden was initiated in 2011 as the result of an endowment by SFA alumnus Ray Mize to honor his late wife Gayla Mize, a long time supporter of Nacogdoches Beautiful, SFA Gardens, and many other civic adventures in Nacogdoches. This garden is a part of the 68-Eve's Necklace, Sophora affinis, is a great small native tree with good flower interest and black seed pods that hang well into the winter. Extremely drought resistant. Mexican buckeye, Ungnadia speciosa, sports redbud like flowers, good fall color and interesting buckeye-like seed. Basically a very large shrub, this drought tolerant species has performed admirably outside of its more western habitats. Texas mountain laurel, Sophora secundiflora, is almost a commodity in central and western portions of the state, but it does remarkably well elsewhere if given good soil drainage and full sun. Beautiful blue fragrant flowers are a key feature, but the evergreen glossy foliage is unusually crisp and clean. A white flowering form is rarely encountered but is quite striking. Possumhaw, Ilex decidua, is one of our favorites. A small multi-stemmed small tree with several varieties in the trade, possumhaws are underutilized in East Texas landscapes. Red or yellow berried. 'Warren's Red' is perhaps the most common variety in the trade, but there's a real need to introduce varieties that sucker less from the ground and from the basal portion of the plant. Yaupon, Ilex vomitoria, is a commodity known for durability, evergreen nature and its ability to tolerate heavy pruning and training. 'Scarlet Peak' is a new variety that is destined to replace 'Fleming's Upright' in the years ahead. Oakleaf Hydrangea, H. quercifolia, is not native to Texas but it's nearby in Louisiana and it's such a superior landscape plant we mention it here. It has surprising drought resistance in our area, but only if soil drainage is superior. It finds the steep banks of Sara's branch at the Pineywoods Native Plant Center so comfortable it's taken to naturalizing along this stream, perhaps a first in Texas? We are evaluating a great list of oakleaf varieties and seedlings. Viburnums are reliable and make great plants for the landscape. Rusty blackhaw, Viburnum rufidulum, and Arrowwood, Viburnum dentatum, are most well known. Viburnum nudum, Smooth withered Viburnum, is showy and durable. Paul Cox, formerly of the San Antonio Botanical Garden, has introduced two great plants that have performed well in landscapes-'Lord Byron' and 'Sir Robert', and both are crosses of V. obovatum and V. rufidulum. While V. obovatum, Walter's Viburnum, is certainly popular and several varieties are available, we've found their suckering nature to be quite frustrating. Cross vine, Bignonia capreolata, is one of our favorite native vines and we love Greg Grant's introduction, 'Helen Fredel'. With big flowers, glossy evergreen foliage and a tenacious habit, there's no better vine. 'Tangerine Beauty' is more readily available. Carolina Yellow Jessamine, Gelsemium sempervirens, sports bright yellow flowers and evergreen foliage. This is a another must have vine for the Texas landscape. Trumpetcreeper, Campsis radicans, is a tenacious vine that deserves respect for its ability to find its way any where it wants to go.

The conference is a unique mixture of plant enthusiasts, nurserymen, landscapers, botanists, academics, and horticulturists. The speakers address native plant concerns, research projects, conservation efforts and landscape use topics. It's a great conference. In fact, the annual July conference has been such a success that the 450 "slots" that the conference can support fill up in just a few days. That response prompted the creation of three satellite conferences representing their specific region. The regional conferences allow for nationally known speakers to address region-specific topics and for participants from near and afar to enjoy the local flora. The Pineywoods Native Plant Center is proud to host the third Cullowhee Lone Star Regional Native Plant Conference. Please thank the speakers for taking time to share with participants. The SF A Mast Arboretum Volunteers deserve a big round of applause for handling so much of the workload that goes into putting on a conference of this scale. Elyce Rodewald, the PNPC and Mast Arboretum's educational programs coordinator, did a masterful job handling registration and program details. Peter Loos, conference co-Director and PNPC volunteer, deserves special thanks for helping with speakers and other program details. Thanks to Martha Sullivan and Roger Hughes for all they have done to ma.ke registration go smoothly. Dawn Stover, Barbara Stump, and Jon Roach are part of what make this place tick, and thanks go out to graduate students Kim Benton, Amanda Camp, Lacey Stokes, LiJing Zhou and Heath Lowery. Michael Clanahan and Keri Blackburn worked tirelessly to keep the preparations running smooth. All the student assistants deserve thanks for pitching in to bring the plant sale to reality and for sprucing up the PNPC gardens. Finally, make sure you thank Greg Grant, the on-the-ground Research Associate for the Pineywoods Native Plant Center, and all the PNPC student workers, for going beyond the call of duty to handle all of the problems that arose in lodging, rooms, meals, tours, transportation, and a myriad of other details. I know they'll be glad to get back to gardening!

As an alternative to a lawn, a natural garden centering upon habitat for butterflies and dragonflies native to the Cajun Prairie is recommended. This gardening experience involves creating a natural garden for ten common, locaJ butterflies. Dragonflies are bonus features. Monitoring the garden is central to our concept.

Their structures were determined by extensive nuclear magnetic resonance and high-resolution electrospray ionization mass spectrometry analyses. High-performance liquid chromatography analytic method for simultaneous determination of the 17 compounds was established and validated. Eleven isolated flavonoids were first evaluated for their free radical scavenging activity using α,α-diphenyl-β-picrylhydrazyl scavenging assay and they showed activity with EC(50) 48.6-172.5 µg mL(-1).
