Native Plant of the Week

Each week throughout 2017 the Port is featuring one native plant that can be found along its properties. The Port uses these 52 featured native plants along with others as part of its sustainable landscape management program.

Look for these native plants along the Port's properties:


WEEK 12
Common Name:  Pacific Wax Myrtle
Scientific Name:  Myrica californica
Pacific Wax Myrtle
 
Wax Myrtle is a large evergreen shrub or small multi-stemmed tree that grows 2-10 meters tall. It has sturdy green leaves 4-13 cm long that give off a spicy scent on warm days. It has greenish flowers born on a spike about 3 cm long. The fruits are small wrinkled purple berries 4-6 mm wide. The fruit have a waxy coating hence the common name Wax Myrtle.

Birds eat the fruit. The wax extracted from the fruit can be used for candles or soap, but the Pacific Wax Myrtle produces less wax than other bayberries so it was rarely used for this purpose. This plant is called “monkey bush” in Stl’atl’imx probably because it was used for some purpose by sasquatches.

FIND IT AT THE PORT: Wax myrtle is an important nitrogen fixing species. It is generally found in wetlands or boggy swampy areas at low elevations. Here it can be found in front of the JKL dock bathroom facility at Swantown Marina.
WEEK 11
Common Name:  Pacific Ninebark
Scientific Name:  Physocarpus capitatus
Pacific Ninebark


Ninebark is a multi-stemmed deciduous shrub that grows to 4 meters tall with brownish bark that peels and shreds on the older stems. The shiny green leaves are alternately arranged, 3-5 lobed, sharply toothed, and deeply veined. The flowers are small and white with 5 petals, and are borne in dense round pom-pom clusters. The fruit are inconspicuous 1 cm reddish berries.

The Nun-chuh-nulth used the wood for children’s bows and other small items. The Cowichan made knitting needles from it. It was generally considered poisonous and a tea from the bark was used as an emetic or purgative. It provides cover, nesting sites and food for birds and small mammals. Deer and elk browse the foliage and bears eat the berries.

FIND IT AT THE PORT:  Ninebark likes moist to wet sites and is frequently found next to water. It has excellent soil binding qualities. At the Port it is found along the shoreline at Swantown Marina between the BC and DEF dock areas and behind the boat launch pay station.
WEEK 10
Common Name:  Roemer’s fescue
Scientific Name:  Festuca idahoensis ssp. roemeri
Roemer's Fescue



Roemer’s fescue is a short, fine textured, native, cool season, perennial bunchgrass. The fine textured leaves are about 10 cm long and come in a wide spectrum of greens and blues. The seed heads are open and found on a stiff stem 35 to 100 cm long. The stem color varies from light green to purple and reds.

Roermeri is a sub-species of Idaho fescue that is native exclusively to the west of the Cascades from Vancouver Island to northern California. It prefers full sun and well-drained soil. It is a good forage plant. It is an important native grass for upland prairie restoration in Western Washington. Bundles of rye grass roots are used by the Makah to rub the body after bathing. The Quinault layer the leaves under Salal berries while they are drying.

FIND IT AT THE PORT: Roemer’s Fescue can be found in the Port’s native prairie garden at the corner of Olympia Ave and Marine Dr.
WEEK 9
Common Name:  Douglas Fir
Scientific Name:  Pseudotsuga menziesii ssp. menziesii
Douglas Fir

Douglas fir is a large pyramidal evergreen conifer with a stiffly erect leader and long spreading to drooping branches. Its dark brown bark is thick and corky and becomes deeply furrowed in older trees. The yellowish green needles are 2 to 3 cm long and have 2 white bands of stomata on their under side. They are spirally arranged around the branches. Its distinctive cones are 8 to 12 cm long with brown scales and are easily recognized by their protruding, papery, three pointed seed bracts.

Douglas fir is the state tree of Oregon. First described by Dr. Menzies, it was named for explorer-botanist David Douglas. The native populations used the plant for various things besides fuel. It was made into spear handles, harpoon shafts, dip-net poles, fish hooks, salmon weirs, and utensils. The pitch was used as a medicinal salve for wounds and skin problems. The pitch was also used as caulk for boats and buckets and as fuel for torches. The cones were thought to have magic powers and were warmed by the fire by the Chehalis and Cowlitz to stop the rain.

FIND IT AT THE PORT: Douglas fir is found throughout the northwest except in the wettest or driest places. It grows best in deep sandy loam soils and full sun. It is a very important timber tree and is often grown as a Christmas tree. It can be found on almost all the Port properties in Lacey, Tumwater and Olympia.
