genera Derwentia, Detzneria, Chionohebe, Heliohebe, Leonohebe and Parahebe included by many botanists. Common names include speedwell, bird's eye, and gypsyweed.
It is a species of Veronica, native to Europe and northern Asia. It is found on other continents as an introduced species. It is a herbaceous perennial plant with hairy stems and leaves. It can grow to 25 cm tall, but is normally about 12 cm tall. The flowers are blue, with a four-lobed corolla. The form of the leaves are similar to white deadnettle.
The 2 to 4 mm wide blossoms of this plant wilt very quickly upon picking, which has given it the ironic name "Männertreu", or "men's faithfulness" in German.
Germander Speedwell is also 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 (Veronica arvensis), the leaves are opposite both on the upper and lower parts of the plant. See the Veronica plant for special weed control considerations.
Uses: Veronica americana is edible and nutritious and is reported to have a flavor similar to watercress. Native Americans used Veronica species as an expectorant tea to alleviate bronchial congestion associated with asthma and allergies. The plant can be confused with skullcap and other members of the mint family. Members of the mint family have square sided stems, and Veronica species have rounded stems, and are easily distinguished from skullcap.
