It produces rosettes in the first year, and bolts a stout, erect stem that is 1 to 4 feet tall, by mid -summer of the second year. Then it flowers and produces fruit. Flowers are reddish -purple (occasionally white) and droop slightly from densely clustered panicles. The five rounded petals are cupped by five sepals covered with long, soft white hairs. Flowering occurs May to July. The simple leaves are lance or oblong shaped, with a smooth edge and no teeth or lobes. Leaves are alternate, 1 to 12 inches long and 1 to 3 inches wide. The leaf tip is sharply pointed, like a hound's tongue, yer are covered with long -soft white hairs. Leaves often appear dusty and insect -ridden. A thick, dark, woody taproot can reach 3 to 4 feet deep. Y] eproduction is solely by seeds. JLN,Seeds are 4 prickly teardrop - shaped nutlets, which are packed in a pyramid -shaped receptacle. Most seeds fall close to the parent plant, but the seeds can travel great distances. The seeds have barbs like Velcro, with a hooked tip that clings to animals, clothing and machinery. A mature plant can produce 2,000 seeds. Seed viability is I to 3 years. Houndstongue is poisonous. Toxic pyrrolixidine alkaloids in Houndstongue stop liver cells from reproducing. Livestock and wildlife may live up to six months after ingesting a lethal dose. Though the plant has a distinctive odor that repels animals, it is more palatable when dried, Animals rarely eat it unless it is dried and mixed with hay. Houndstongue`s toxicity effects horses and cattle more severely, sheep seem more resistant. Burs will reduce the value of sheep wool if present. Habicacs for Houndstongue are open to shady, moist, disturbed areas, along trails, roadsides, fields, pasture, rangeland, along the edge of forests, sand dunes and ditch banks. Houndstongue prefers moist areas, but ofren grows on sandy or gravelly alkaline soil up to 9,000 feet elevation. Areas with more than 10% bare ground are particularly vulnerable to Houndstongue invasions. The key to effective control of Houndstongue is preventing establishment and to prevent seed dreduction. Planting com etin and esirable grasses and forbs can be effective. Helping with reestablishment of disturbed sites. An integrated weed management approach can also be successful. Chemical, mechanical, and biological controls can be effective when dealing with Houndstongue. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Houndstongue is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations. For more information visit www.colorado. v a csd and click on the Noxious cad Management Program.

Updated on: 08/09 Redstem filaree Identification and Management Identification and Impacts Redstem filaree (Erodium cicutarierm) is a winter annual or biennial forb that has a spreading or erect profile and is native to the Mediterranean or Asia. Part of the Geranium family, Redstem filaree grows generally from a rosette stage, and can grow from the 3 inches to 2 feet tall. The stems are hairy and red in color. The leaves are opposite and finely divided with toothed or lobed margins. They are pubescent, grow on short stems and have a reddish tint. The root system is a shallow taproot with fiberous secondary roots. The five petaled flowers are a purplish -pink in color and are in clusters of 2 or more. Each flower will produce five long lobed fruits. Each fruit will have an awn like tail which will dry and split with maturity. Redstem filaree primarily reproduces by seed and generally germinates in early spring. Habitats for Redstem filaree include: dry pasturelands, landscapes, turfgrass and it prefers sandy soils. It can easily outcompete desirable vegetation once established. Redstem filaree h drought tolerant and can withstand a heavy stocking rate. The plant is grazed by many different animals especially sheep. The key to effective control of Redstem filaree is preventing establishment of the plant and seed production. There are many options for control of Redstem filaree depending on site ecology. Both chemical and mechanical control options are effective. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Redstem filaree is designated as a "List C" sppecies in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.
