Veronica chamaedrys, the germander speedwell, bird's-eye speedwell, or cat's eyes, [1] [2] is a herbaceous perennial species of flowering plant in the plantain family Plantaginaceae.
Veronica chamaedrys can grow to 20 cm (7.9 in) tall, [3] but is frequently shorter, with stems that are hairy only along two 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, 8–12 mm (0.3–0.5 in) wide. The capsules are wider than they are long. [4] : 591
The blossoms of this plant wilt very quickly upon picking, which has given it the ironic name "Männertreu", or "men's faithfulness" in German. [5]
Veronica chamaedrys is a common, hardy turf so-called 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 species, such as corn speedwell (Veronica arvensis), [6] the leaves are opposite on both the upper and lower parts of the plant. [7] [8] See Veronica for special weed control considerations.
The specific name chamaedrys is a combining form meaning "low" or "on the ground" derived from ancient Greek. [9]
This species is native to Europe. [10] It is found on other continents as an introduced species.
Veronica chamaedrys has been used in traditional Austrian herbal medicine internally (as tea) for disorders of the nervous system, respiratory tract, cardiovascular system, and metabolism. [11] 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.

Glechoma hederacea is an aromatic, perennial, evergreen creeper of the mint family Lamiaceae. It is commonly known as ground-ivy, gill-over-the-ground, creeping charlie, alehoof, tunhoof, catsfoot, field balm, and run-away-robin. It is also sometimes known as creeping jenny, but that name more commonly refers to Lysimachia nummularia. It is used as a salad green in many countries. European settlers carried it around the world, and it has become a well-established introduced and naturalized plant in a wide variety of localities. It is also considered an aggressive invasive weed of woodlands and lawns in some parts of North America. In the absence of any biological control, research conducted by the USDA herbicides are relied upon particularly for woodland ecosystems. The plant's extensive root system makes it difficult to eradicate by hand-pulling.
Matricaria chamomilla, commonly known as chamomile, German chamomile, Hungarian chamomile (kamilla), wild chamomile, blue chamomile, or scented mayweed, is an annual plant of the composite family Asteraceae. Commonly, the name M. recutita is applied to the herbal product chamomile, although other species are also used as chamomile. The plant is commonly used to make a tea.
In biology, stolons, also known as runners, are horizontal connections between parts of an organism. They may be part of the organism, or of its skeleton. Typically, animal stolons are exoskeletons.
Sambucus ebulus, also known as danewort, dane weed, danesblood, dwarf elder or European dwarf elder, walewort, dwarf elderberry, elderwort and blood hilder, is a herbaceous species of elder, native to southern and central Europe and southwest Asia. The species is a well-established archaeophyte in much of the UK, and is also reportedly naturalized in parts of North America.
Veronica officinalis, the heath speedwell, common gypsyweed, common speedwell, or Paul's betony, is a species of flowering plant in the plantain family Plantaginaceae. It is native to Europe and western Asia. It has been introduced to North America and is widely naturalised there.
Veronica is the largest genus in the flowering plant family Plantaginaceae, with about 500 species. It was formerly classified in the family Scrophulariaceae. Common names include speedwell, bird's eye, and gypsyweed.
Spergula arvensis, the corn spurry, stickwort, starwort or spurrey, is a species of plant in the genus Spergula.
Thunbergia laurifolia, the laurel clockvine or blue trumpet vine, is native to India and Thailand and the Indomalayan realm, the species occurs from Indochina to Malaysia.
Scutellaria lateriflora, is a hardy perennial herb of the mint family, Lamiaceae, native to North America.
Veronica arvensis, common names: wall speedwell, corn speedwell, common speedwell, rock speedwell, field speedwell, is an annual flowering plant in the plantain family Plantaginaceae. The species is native to Europe and a common weed in gardens, pastures, waste places, and cultivated land.
Veronica serpyllifolia, the thyme-leaved speedwell or thymeleaf speedwell, is a perennial flowering plant in the plantain family. It is native to Europe, but can be found elsewhere on most continents as an introduced species.
Arvensis, a Latin adjective meaning in the fields, is the specific epithet of the following:
V. arvensis may refer to:
Veronica anagallis-aquatica is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, blue water-speedwell,brook pimpernel.
Veronica filiformis is a species of flowering plant in the family Plantaginaceae. It is known by many common names, including slender speedwell, creeping speedwell, threadstalk speedwell and Whetzel weed. It is native to eastern Europe and western Asia, and it is known in many other regions as an introduced species.
Veronica peregrina is a species of flowering plant in the plantain family known by several common names including neckweed, American speedwell, purslane speedwell and hairy purslane speedwell. It is native to the Americas, and is known on other continents as an introduced species and a common weed. It can be weedy in its native range as well, growing on roadsides, on fields, and in other disturbed habitat. It is an annual herb growing from a taproot. The two subspecies are defined generally on the basis of hairiness: ssp. xalapensis is coated in glandular hairs and ssp. peregrina is a hairless variety. The plant produces erect stems up to about 30 centimeters tall. The leaves vary in shape from linear to lance-shaped to spoon-shaped with smooth or serrated edges; the lower leaves are borne on petioles. The inflorescence is a loose terminal raceme of flowers and lance-shaped bracts. The flowers are generally white and 2 or 3 millimeters wide.
British NVC community OV15 is one of the open habitat communities in the British National Vegetation Classification system. It is one of two arable weed communities of light lime-rich soils.
Alnus alnobetula is a common tree widespread across much of Europe, Asia, and North America. Many sources refer to it as Alnus viridis, the green alder, but botanically this is considered an illegitimate name synonymous with Alnus alnobetula subsp. fruticosa.
Teucrium canadense, commonly known as Canada germander, American germander, or wood sage, is a perennial herb in the family Lamiaceae. It is native to North America where it is found across the contiguous states of the United States and in much of Canada.
