Veronica chamaedrys (germander speedwell, bird's-eye speedwell, cat's eyes<ref>Template:Cite web</ref><ref>Template:Cite web</ref>) is a herbaceous perennial species of flowering plant in the plantain family Plantaginaceae.
It can grow to 50 cm tall, but is frequently shorter, with stems that are hairy only along 2 opposite sides. The leaves are in opposite pairs, triangular and crenate, sessile or with short petioles. The flowers are deep blue with a zygomorphic (bilaterally-symmetrical) four-lobed corolla, 8 to 12 mm wide. The capsules are wider than they are long.<ref name=Stace>Template:Cite book</ref>Template:Rp
The blossoms of this plant wilt very quickly upon picking, which has given it the ironic name "Männertreu", or "men's faithfulness" in German.<ref>Friedhelm Sauerhoff, Pflanzennamen im Vergleich: Benennungstheorie und Etymologie [Plant names compared: theory of naming and etymology] (Stuttgart, Germany: Franz Steiner, 2001), page 206: Das bestätigt auch E. Mießner, wenn er zum Gamander-Ehrenpreis feststellt: "Da die Blüten leicht abfallen, auch deutscher Spottname 'Männertreu'..." (E. Mießner also confirms that, when he observes about Veronica chamaedrys: "Since the blossoms easily fall off, [it is] also [known by] the derisive German nickname, 'men's faithfulness'...")</ref>
Germander Speedwell is a common, hardy turf weed when it invades turf and lawns. It creeps along the ground, spreading by sending down roots at the stem nodes. It is propagated both by seed and stem fragments. Leaves may defoliate in the summer and winter but the stems will grow again next season. Unlike at least five other common speedwell turf weeds such as corn speedwell<ref>other Turf Weeds at Virginia Tech: corn speedwell, Veronica arvensis http://turfweeds.contentsrvr.net/category_detail.pg_24.vesh</ref> (Veronica arvensis), the leaves are opposite both on the upper and lower parts of the plant.<ref>Turf Weeds at Virginia Tech; germander speedwell, Veronica chamaedrys: http://turfweeds.contentsrvr.net/category_detail.pg_17.vesh</ref><ref>Weed ID & info; Department of Crop and Soil Sciences, Michigan State University and Ronald Calhoun: http://www.msuturfweeds.net/details/_/germander_speedwell_13/</ref> See the Veronica for special weed control considerations.
It is native to Europe and Asia west of the Ural Mountains.<ref>http://linnaeus.nrm.se/flora/di/scrophularia/veron/verochav.jpg</ref> It is found on other continents as an introduced species.
Veronica chamaedrys herb has been used in the traditional Austrian medicine internally (as tea) for treatment of disorders of the nervous system, respiratory tract, cardiovascular system, and metabolism.<ref>Template:Cite journal</ref> In 18th century Britain, the plant had the reputation of being a cure for gout as well as being popular for making tea, the latter being so prevalent that the plant was nearly eradicated from London during the 18th century.<ref>Template:Cite book</ref>
