About Portland

Portland is the “City of Roses,” and there is frankly no better place to stop and smell them. Roses grow everywhere, as do tulips, camellias, and rhododendrons, blossoming for blocks on end. Emerald-forested hills create a natural amphitheater that cradles this urban village, with fingers of green reaching into it, making the mere act of walking down a street a refreshing and invigorating experience.

Venue and Accommodationssmith-mem-stud-union-2

The Symposium has made arrangements for dorm rooms on campus at the Broadway Residence Hall at Portland State University.  The Broadway Residence Hall is about 1 block from the conference meeting room.  The Broadway Residence Hall is an eleven-story student residence located at the corner of SW Broadway and Jackson Street with its northern-wing extending to SW College Street and its eastern-wing to SW 6th Ave. The housing portion of the building consists of studio apartments which include two twin beds in each. There is no obligation to book rooms at the dorm and attendees are welcome to make accommodations as you desire in the city.

The Portland State University dorms are modern, comfortable, and very affordable.  However, they do not come equipped with air conditioning.  The climate in Portland throughout August typically does not warrant air conditioning due to mild temperatures and arid climate, although weather is unpredictable and uncomfortably hot temperatures do occur sometimes. Most hotels in Portland provide air conditioning if you are more comfortable with that feature.  Please consider this before you decide to book rooms at the Portland State University dorms.

Disabilities Act

The symposium will make all reasonable efforts to accommodate persons with disabilities at the meeting. The university is in compliance with the Americans with Disabilities Act. Please indicate your special needs when making your reservations at the dorms.


The exhibit hall will be open from Monday, August 21, through Thursday, August 24. There will be approximately 50 exhibit booths allowing registrants the opportunity to examine state-of-the-art products and services. An exhibit prospectus can be obtained by contacting meeting director/secretariat Marietta W. Ellis at (910) 755-5431, fax (910) 755-5432, or email:

Sunday Scientific Tours

Sunday, August 20 will be a half day tour of venues of interest to meeting attendees. Here is a list of some of the places you will get to visit:

monrovia-logoMonrovia  utilizes an aerated static pile compost system with feedstock comprised disease free plants that do not meet quality standards. This high quality compost is recycled into the custom soil blends. Monrovia has a reputation as an industry leader in developing and implementing systems to reduce the use of pesticides and hazardous chemicals, improve water recycling and establishing reuse/recycle programs throughout the company. Their compost system is part of their ongoing efforts in innovation and conservation. Since their founding by Harry E. Rosedale in 1926, the name Monrovia has been synonymous with plants that Grow Beautifully. Harry Rosedale was one of the early pioneers to grow plants in containers. It was a revolutionary idea, but he saw that plants would endure less trauma and transplant better if they remained in their containers until they were ready to be planted in the landscape. The challenge was to create an environment of soil that allowed the plants to flourish. They have continually improved our soil mixes, developed better irrigation systems and led the way with a series of horticultural breakthroughs resulting in extraordinarily healthy plants that will not only survive, but thrive, in home gardens. Today, they grow more than 4,000 varieties and 22 million plants annually, but each one is nurtured by hand with care to assure it is truly will Grow Beautifully.

carlton-plantsCarlton Plants LLC manages active windrowed, irrigated compost piles comprised of unsold or culled, disease-free trees, horse manure, and other disease-free Willamette Valley specialty crop byproducts. Temperature and moisture content are monitored throughout the composting process. Chemical and biological properties are determined prior to use as a soil amendment for shade tree production. Their compost is one of the many facets that show the companies dedication is conservation, resource management and sustainable land use.Carlton Nursery began growing prune trees for the commercial orchard industry in 1890 in the town of Carlton. As the company grew it moved to different and larger pieces of property to accommodate its need for land. In 1971, the nursery finally settled in Dayton, Oregon on 600 acres at the site of the historic Alderman Farms. The farm was originally one of Oregon’s largest fruit and vegetable growers in the late 1800’s and until the early 1940’s. After purchasing the property, we retained and renovated many Alderman barns and shops, including the granary, which is now our main office facility. Since 1971, the nursery has acquired additional ground and now operates on approximately 1,850 acres. Today Carlton Plants continues to provide quality bareroot trees (shade, ornamental and fruit), ornamental shrubs and rootstocks to growers, landscapers, retail garden centers, landscape contractors, and others engaged in the nursery industry.
