Why Is It a Noxious Weed?
Wand loosestrife is difficult to distinguish from purple loosestrife and it too has the potential to invade and spread within wetlands. It is listed on the Washington State Department of Agriculture’s prohibited plants list (quarantine list).
How would I identify it?
Wand loosestrife is similar to purple purple loosestrife but is smaller, hairless and smooth (glabrous) with narrower leaves and flowers are mostly paired or clustered in leafy, open flower clusters (racemes).
Flower clusters 5.1 to 9.8 inches long, at stem ends (terminal). Flowers in 1-3 (up to 7) flowered sub-groups (axillary cymes) that are single or in sparse whorls. Narrow bracts are throughout flower cluster. Flower petals purple to pink.
Leaves are hairless, oppositely arranged (sometimes alternately), narrowly lance-shape to linear lance-shape with tapered bases. Leaf length: 1.2 to 5.1 inches; leaf width: by .1 to 1.6 inches.
Stems are upright and 4-angled, growing up to 3.25 feet tall.
