Corolla scarcely two-lipped, pinkish white, 1.5 - 2 cm long, tubular, five-lobed (upper lip four-lobed, divided nearly to base; lower lip a single lobe), hairless outside, hairy inside.

Flowering: May to June

Habitat and ecology: Introduced from Eurasia. Escaped from cultivation. Occasional in waste ground, thickets, and along fencerows and woodland edges.

Occurence in the Chicago region: non-native

Etymology: Lonicera is named after Adam Lonicer (1528-1586), a German botanist and author. Tatarica means "of or from the Tatar Mountains," which are in Russia.
