A walking tour of PLU. Look at our cool plants!
From left to right: Golden-tipped Kryptimanria, Swiss Stone Pine, and Camillia Winterblooming. These plants, which were relocated to other parts of campus, are edible upon full bloom.
Here is an initial tree tour for your lunch time walks...
Along the sidewalk: Allee of Maidenhair trees (Gingko biloba). Are a brilliant yellow during the fall season. They drop all of their leaves practically overnight. Only a few of these trees exhibit the regular growth habit. There is another Maidenhair on campus. Make sure to plant only the male trees--the female trees produce a fleshy fruit that is ill smelling. This is one of earth’s oldest trees. It has been growing for 150 million years and was indigenous to North America. (See Vantage WA, Petrified Forest). Now it is grown in China.
The Quince (Cydonia oblonga) has been under cultivation since very remote times. It is a native of Persia and Anatolia and perhaps also of Greece and the Crimea. It produces a soft, juicy fruit after it blooms.
Far West: One lone pear tree (Pyrus). It produces a lot of bosc-like pears in the fall. Help yourself!
East: Three beech trees (Fagus sylvatica). They have a nice fall color and an interesting horizontal branch habit. Note the smooth muscled bark indicative of the genus Fagus.
Red Square: The tree which forms the allees along the campus walks are honey locusts (Gleditsia triacanthos). They are members of the pea family. These trees were planted around 1965 to help organize the upper campus landscape. Much of the upper campus landscape was designed in the office of Richard Haag—the father of Northwest Landscape Architecture. Mr. Haag still teaches a few classes at the University of Washington. He is known for the landscape architecture of Gas Works Park in Seattle, Victor Steinbrueck Park, the Seattle Center, and the Seattle Federal Building. Currently he is working on a central design for the University of California, Berkeley. PLU has a special heritage in this landscape.
South: A grove of European Birch (Betula pendula). Several of the trees were replaced with new trees after the ice storm damage. An Estonian family--displaced as a result of World War II and sponsored by President Eastvold--donated the original grove to thank PLU for its kindness to them when they began life in the United States.
Southwest: A small grove of tulip trees (Liriodendron tulipifera). In late spring there are tulip-shaped greenish, yellow flowers. These are native to eastern US.
West: Three poplars (Populus nigra ‘Italica’).
Hauge Administration Building
Entryway: Two paperbark maples (Acer griseum). The bark is interesting in its copper color and peeling, curling nature.
West parking lot : The large trees are the London plane tree (Platanus acerifolia).
West: California Bay Laurel (Umbellularia californica). Crush the leaves for the bay leaf smell. This tree is evergreen.
North Square (north of the fountain): 4 disease resistant trees (Malus ‘Prairiefire’). They bloom pink flowers like the former trees.
South: The trees are flowering pear (Pyrus calleryana). Look for white spring blossoms and good fall color.
Base of the hill below: Two river birch trees (Betula nigra). Look closely, (but do not strip) at the soft pink bark underneath the peeling white bark.
Stairway: Wildlife Recruitment Tree. Look for nesting birds and small mammals in this area; this tree is for bird nesting. PLU had the top cut off a damaged tree to create a snag.
West (on path through woods): Big Oak Tree, possibly 300 years old.
Alongside the building: Three southern Magnolias (Magnolia grandiflora). They have very fragrant blooms.
Entryway: Three Spanish Firs (Abies pinsapo ‘glauca’). These firs had some trouble with disease in the last few years. We hope to have corrected water problems and insect problems. They are presently under study. We replaced one, which died. They are slow growing, native to Spain.
North end: Two Giant Sequoia (Sequoiadendron giganteum) dominate this area. This is the Redwood found in the California Mountains. See the upper campus for the Coast Redwood.West end : A new flowering apricot (Prunus mume) planted last year. Look for small fragrant bloom in early spring.
Southeast (near the parking lot): There is an ash tree (Sorbus intermedia ) reportedly from the original Stuen property donated to the University. This ash is native to Norway.
Entry: 4 new Japanese Snowdrop trees (Styrax japonicus). They have small white flowers that dangle along each branch.
Parking Lot (About 60 feet from the corner of Park and 125th): A Frasier Fir (Abies fraseri). It is native to the southern Appalachians.
Entry: Two Giant Sequoia (Sequoiadendron giganteum) dominate this area. This is the Redwood found in the California Mountains. See the upper campus for the Coast Redwood.
Around Various Campus Areas
Hillside Climbs: These nice stair climbs give you a chance to see a lot of native and nonnative species. The Douglas fir, White Oregon oak, the cherry and many shrubs provide food and shelter for birds and small animals. The English holly, laurel, ivy and scotch broom are invasive species. A lot of Himalayan Black berry crops up in sunny paces too.Upper Campus Malls: Douglas fir trees (Pseudotsuga menziesii) give our campus a nice arching structure. These trees and others are under study to determine which are hazardous trees and need to be replaced. The tree tags help us get our records built.
Main Mall: One coast redwood (Sequoia sempervirens).
Nurse logs: One log--cut in two--was brought off the Cascade slopes during this area’s creation. The nurse logs support all sorts of plant and animal life. Take a close look.
Wild Area: The small groups of trees and shrubs are clustered in associations, with some interlopers and invasive species springing up.
