  • Dogwood tree – Cornus kousa

    One of the most beautiful flowered trees in the park is our dogwood, located near the circle entrance to the park, off of Bruce Street. Every year in the late spring, it blooms profusely with its large white flowers. The flowers themselves are tightly clustered, lacking showy petals, but surrounded by four to six large, typically white petal-like bracts. Bracts are actually modified or specialized leaves.

    The unique fruits are raspberry-like and they persist into winter. They are edible and are sometimes used for making wine. More than 35 species of birds will eat the high-fat, fleshy and red fruit.

    How did the dogwood get its name? The name “dog-tree” entered the English vocabulary by 1548, and had been further transformed to “dogwood” by 1614. There are a couple of theories as to the origin of the name. One thought is that “dogwood” was derived from the Old English dagwood, from the use of the slender stems of its very hard wood for making “dags” (daggers, skewers, and arrows). Another earlier name of the dogwood in English is the whipple-tree. A whippletree is an element of the traction of a horse-drawn cart, linking the drawpole of the cart to the harnesses of the horses in file; these items still bear the name of the tree from which they are commonly carved.

    While there is a native Pacific dogwood, our dogwood is of Asian origin.

  • Giant Sequoia – Sequoiadendron giganteum

    Here in Pier Park there is a significant grouping of 29 giant sequoias and one coastal redwood located upon a knoll at the north end of the park. Giant sequoias are the world’s largest single trees by volume and given the right environment, they are known for their longevity, living up to 3,000 years.

    These sequoias are infants, being planted 60 years ago. From a distance you can see the gigantic pyramidal shaped trees. Crossing over the bridge from Chimney Park, bikers and walkers will be greeted by these gentle giants. From the bridge, the path winds through this grove of sequoias.

    Though sequoias trees themselves are large and strong, they have feeder roots that are fragile, tender and shallow. Because the health of the giant sequoias depend on these roots for hydration, it is important to take care when treading in the grove.

    The bark of the sequoia, which can grow to an impressive 3 feet in thickness, is fibrous and absorbs moisture somewhat like a sponge for the tree. This blanket of bark helps to protect these trees from lightening strikes and fire.

    A sequoia is not only a tree but a unique ecosystem unto itself providing food and shelter to insects such as beetles and butterflies as well as robins and chipmunks, squirrels and bats. Pause. Admire the height and girth of the trees. Pier Park is blessed to have this grove of giant sequoias within its family of trees.

    The National Park Service provides a wonderfully detailed description and history of the giant sequoia.

  • Douglas Fir – Pseudotsuga menziesii

    Walk through Pier Park and you find yourself walking under the high canopy of Oregon’s state tree  – the Douglas fir. Douglas firs definitely dominate the park’s landscape.  Coastal Douglas firs are the 2nd tallest trees in the world (2nd to the Redwood) and can live between 500 – 1000 years old.

    Douglas firs, named after the famous Scottish botanist, David Douglas, are not true firs. Unlike a true fir its cones grow downward. Seeds from the cones, easily identified by the 3-forked looking bracts, are a favorite food of the park’s squirrels, which eat them like corn on the cob. Watch for squirrel “middens” – piles of cone scales –and chewed cones on your next walk. Douglas fir needles are the sole diet of the Red Tree Vole.

    Coast Douglas fir is one of the world’s best timber producers. Its wood is widely used for dimensional lumber, flooring, railroad ties and plywood. Its sap is a source for glue and photo supplies from its sap. This is the nations most popular Christmas tree.

    Summer in Pier Park would not be the same without the shade of our Douglas firs.
