  • Shiny Geranium (Geranium Lucidum)
    KING COUNTY NOXIOUS WEED ALERT Shiny Geranium Class B Noxious Weed: Control Required Geranium lucidum Geranium Family Identification Tips • Low-growing annual with tiny, pink, 5-petaled flowers that grow in pairs on short stems • Leaves shiny, round to kidney-shaped with 5-7 lobes • Sepals keeled • Stems reddish, smooth (hairless), up to 20 inches tall • Seeds form in capsules with a long, pointy “crane's bill” Biology Reproduces by seed. Seeds are forcefully ejected when ripe, helping it spread up as well as out from parent plants. This is probably why this plant can be found in crevices of tree trunks or spreading up hillsides. Usually grows as an annual but some plants live for two years. Flowering is from April to July and seeds mature and spread usually from late June Ben Legler by Photo to early July. Seeds germinate mostly in late summer to early fall, but can Look for pairs of tiny pink flowers, germinate several times a year. winged sepals with “keels”, and shiny, rounded, lobed leaves. Impacts Can invade and overwhelm high quality native habitat in forests and grasslands. Spreads quickly by seed and forms dense carpets, excluding other vegetation. Contaminates nursery stock and can be accidentally introduced to landscaped areas and restoration sites. Distribution Introduced from Europe and Asia. In the Pacific Northwest, most abundant in Oregon in the Willamette Valley and the Portland area. Also increasingly found in many counties of western Washington. In King County, it is found in both urban and rural areas in yards, woodlands, roadsides and spreading from landscaped areas.

  • Spurge Laurel Other Common Names: Daphne, Daphne- USDA Symbol: DALA11 Daphne Laureola Spurge, Daphne-Laurel ODA Rating: B
    Spurge laurel Other common names: daphne, daphne- USDA symbol: DALA11 Daphne laureola spurge, daphne-laurel ODA rating: B Introduction: The Daphne family consists of 500 species mostly small shrubs or occasional herbs. Most members of the group produce stem fibers and a few are used for papermaking in Asia. Spurge laurel was planted throughout the Pacific Northwest for decades. It is a native in much of Western Europe and the southern countries of Eastern Europe. Southern British Columbia, especially southern Vancouver island and in the Vancouver area, have well-established populations of spurge laurel. In Washington State, many west-side counties have escaped populations near urban areas. The hard seeds are consumed by birds and transported off-site Distribution: Oregon spurge laurel infestations are increasing. The largest infestations are located in Yamhill, Douglas and Benton counties. The Columbia River Gorge also contains outbreaks of the weed. Deciduous forests are the perfect habitat providing partial shade for the shrubs though conifer forests are equally suitable especially along the edges. Description: Spurge laurel is an attractive ornamental plant known for its spiraling evergreen leaves and greenish-yellow, bitter-fragrant flowers. Larger patches emit an unpleasant odor. Flowering occurs in late winter-early spring, producing clusters of blue berries during the spring. The one-seeded drupes are eaten and dispersed widely by birds and small mammals. Shrubs reach a height of 0.5-1.5 meters. This weed tolerates low light levels from partial to deep shade. It prefers better-drained clay loams and forest loams with neutral to acidic soils. Escaped populations form dense stands mostly under tree canopies.

  • HERB ROBERT (Geranium Robertianum) of the Geraniaceae Family Also Known by the Names of - Herb Robertianum, St
    HERB ROBERT (Geranium Robertianum) of the Geraniaceae family Also known by the names of - Herb Robertianum, St. Robert, Storkbill, Cranesbill, Red Robin, Fox geranium, St. Robert’s Wort, Bloodwort, Felonwort, Dragon’s blood. This list of common names gives a rather vivid description, of a small plant that I have come to revere, and it is always welcome, in my garden. Description Annual, to 30-40cm, stems branch in many directions, and these stems may turn red, in colour. Green leaves, 6cm long, form opposite, at knotted joints in the stem; leaves are palmate in shape, deeply cut, and often tinged with colours of pink, red or bronze. Stems and leaves are covered with very fine hairs. Very dainty, bright-pink, ‘joy giving’ flowers, 15mm across, have five, rounded petals. Each petal has 3 streaks of white, starting at the centre and phasing out along the petal. Flowers develop, in groups of 2 or 4, at leaf axils. The base of the blossom quickly fills out, develops into the oval seed receptacle, 17mm long, and when mature, looks like a bird’s beak, which is why the plant has been given the common names: ‘storkbill’ and ‘cranesbill’. As the seeds dry off, nature has a way of dispersing: by opening the ‘beak’ and ejecting with a sudden spring action, flinging the 5 small, oval seeds in five directions, ensuring that there will be future generations of the plant, for mankind’s use. I believe this plant should be in every garden, ready for service. Propagation is by seed. Plants thrive in shady, damp places, growing very quickly, flowering profusely, and self-seeding readily: if the seed is not picked, before it is dry.

  • Weed Risk Assessment: Centaurea Calcitrapa
    Weed Risk Assessment: Centaurea calcitrapa 1. Plant Details Taxonomy: Centaurea calcitrapa L. Family Asteraceae. Common names: star thistle, purple star thistle, red star thistle.

Naturalised Distribution: Naturalised in New Zealand, South Africa, Central America, South America, the United States of America (eg. naturalised in 14 states, mostly in northwest including California, Idaho, Washington, Wyoming, New Mexico, Oregon, Arizona) (USDA plants database), and Australia (GRIN database). Description: C. calcitrapa is an erect, bushy and spiny biannual herb that is sometimes behaves as an annual or short-lived perennial. It grows to 1 m tall. Young stems and leaves have fine, cobweb-like hairs that fall off over time. Older stems are much-branched, straggly, woody, sparsely hairy, without wings or spines and whitish to pale green. Lower leaves are deeply divided while upper leaves are generally narrow and undivided. Rosette leaves are deeply divided and older rosettes have a circle of spines in the centre. This is the initial, infertile, flower head. Numerous flowers are produced on the true flowering stem and vary from lavender to a deep purple colour. Bracts end in a sharp, rigid white to yellow spines. Seed is straw coloured and blotched with dark brown spots. The pappus is reduced or absent. Bristles are absent. Seeds are 3-4mm long, smooth and ovoid. The root is a fleshy taproot (Parsons and Cuthbertson, 2001) (Moser, L.

  • Spurge Laurel Management
    Control Options for Spurge Laurel General Information Spurge laurel (Daphne laureola), a shrub native to Western Europe and the Mediterranean, was introduced into North America as a garden ornamental. It has escaped cultivation, invading roadsides, parks and wooded areas. Spurge laurel reproduces both by seed and vegetatively, by sprouting from lateral roots. The berries are eaten by birds, which aids in seed dispersal. All parts of the plant are poisonous to humans, as well as to dogs and cats. Manual/Mechanical Techniques Small infestations of spurge laurel can be hand dug or pulled using a weed-pulling tool, such as a Weed Wrench™. Weed Wrenches and Extractigators™ are available for loan from the Whatcom County Noxious Weed Program. Please call (360)778-6232 or (360)778-6234 for more information. Young plants (3 yrs. or less) will often die after being cut close to the ground. For older plants, control may also be possible by cutting the plant off, but make sure the cut is below the ground surface. The sap of spurge laurel contains irritating toxins. Care should be taken to prevent the sap from coming into contact with the skin or eyes. Respiratory irritation has also been reported from inhaled droplets of sap. Chemical Recommendations Spurge laurel can be managed using specific herbicides. When using herbicides, always read and follow label directions for rates, spraying conditions, personal protective equipment and grazing intervals. If spraying is the chosen option, spray late in the evening to reduce the direct impact on pollinating insects. Do not spray when it is windy or raining, or when rain is forecast.

Fruits: The carpels are pubescent with tiny hairs and noticeably 5-ridged lengthwise. Each mericarp is longitudinally rugose-reticulate (wrinkly with a networked appearance) and along the sutures are glandular- uncinate (hooked at the tip).
