Purple Loosestrife Lythrum Salicaria L
Weed of the Week Purple Loosestrife Lythrum salicaria L. Native Origin: Eurasia- Great Britain, central and southern Europe, central Russia, Japan, Manchuria China, Southeast Asia, and northern India Description: Purple loosestrife is an erect perennial herb in the loosestrife family (Lythraceae), growing to a height of 3-10 feet. Mature plants can have 1 to 50 4-sided stems that are green to purple and often branching making the plant bushy and woody in appearance. Opposite or whorled leaves are lance-shaped, stalk-less, and heart-shaped or rounded at the base. Plants are usually covered by a downy pubescence. Flowers are magenta-colored with five to seven petals and bloom from June to September. Seeds are borne in capsules that burst at maturity in late July or August. Single stems can produce an estimated two to three million seeds per year from a single rootstock. The root system consists of a large, woody taproot with fibrous rhizomes. Rhizomes spread rapidly to form dense mats that aid in plant production. Habitat: Purple loosestrife is capable of invading wetlands such as freshwater wet meadows, tidal and non-tidal marshes, river and stream banks, pond edges, reservoirs, and ditches. Distribution: This species is reported from states shaded on Plants Database map. It is reported invasive in CT, DC, DE, ID, IN, KY, MA, MD, ME, MI, MN, MO, NC, NE, NH, NJ, NY, OH, OR, PA, RI, TN, UT, VA, VT, WA, and WI. Ecological Impacts: It spreads through the vast number of seeds dispersed by wind and water, and vegetatively through underground stems at a rate of about one foot per year. -

F a C T S H E E T Purple Loosestrife
JEFFERSON COUNTY NOXIOUS WEED CONTROL BOARD F A C T S H E E T PURPLE LOOSESTRIFE (Lythrum salicaria) Purple loosestrife can be ten feet tall at maturity. The multiple stems are squarish with four to six sides. The leaves are up to four inches long, usually lance- shaped, with smooth edges. The magenta-colored flowers, which bloom from July to October, appear tightly clustered on tall spikes. Loosestrife family. LOOK ALIKES: Fireweed, (Epilobium angustifolium— native), commonly grows in drier ground than purple loosestrife, and does not have a square stem. Cooley’s hedgenettle, (Stachys cooleyae—native) seldom grows taller than four feet, and the plants are not branched or bushy. The leaves are nettle-like, with toothed edges. Butterfly bush, (Buddleja spp.), is a WHY BE CONCERNED? garden ornamental which invades riparian areas. It has a round stem, and Purple loosestrife invades wetlands and the bright purple flowers grow in a tightly displaces native vegetation. packed flower head. It supplies little food or habitat to wildlife. Purple loosestrife is a Class B Noxious Weed. Control is required in Jefferson County. Hardhack, (Spiraea douglasii— native), has a round stem and fluffy, pinkish flowers arranged in tight clusters. 380 Jefferson Street, Port Townsend WA 98368 360 379-5610 Ext. 205 [email protected] http://www.co.jefferson.wa.us/WeedBoard DISTRIBUTION: Purple loosestrife has been found in at least 8 locations in Jefferson County. Most are small, have been hand-pulled and will be monitored closely. One large infestation responded very well to bio-control. ECOLOGY: Purple loosestrife grows in wet sites, especially ones that have been disturbed by human activity. -

Screen Stars by Janet Davis
Screen Stars Use plants that have open, see-through flowers and stems as scrims and screens to bring drama to the garden. BY JANET DAVIS EYOND THE basics of designing a border with appropriate plants Bchosen for their color, height and shape, there is another more ethe- real quality common to a small roster of plants that makes them ideal for adding movement, light, and a sense of enigma to a planting scheme. These are the “see- through” or “scrim” plants. In theater parlance, a scrim is a gauzy, transparent curtain that allows the audience to see through it to a scene being played out in the background. In garden design, such plants fulfill their own roles while encouraging viewers to look through them to other plants or distant corners of the garden. They can also be used as seasonal exclamation points and to par- tially screen views—around a patio or pool, for instance—without obscuring the view completely. The best see-through plants feature tall, wiry stems topped by small or very airy, loose flowers or inflorescences that sway easily in the wind, in delicate con- trast to their more stolid neighbors. The flowers might be slender spikes that create vertical brushstrokes against background plants, bouncing balls that lend a kinetic quality to a planting scheme, or flowers Native to South Africa, wandflower or angel’s fishing rod (Dierama pulcherrimum) is a grassy- that create a hazy effect that invites a look DOREEN WYNJA looking perennial growing to six feet tall that bears drooping stems of pink flowers in summer.
