Pronunciation guide: (phonetic spelling) al-ee-AR-ee-uh pet-ee-oh-LAH-tuh Flower name (common): Garlic Mustard Family name (common): Mustard Family name (scientific): Brassicaceae Scientific name origin: Genus: Allium - garlic; Medieval (11th-15th centuries). Specific epithet: From petiole, which in Botany, is the stalk that attaches the leaf blade to the plant stem. Common name origin: The garlic-like odor from the crushed plant and the similarity with other mustard plants lead to the common name. Flower description: Size: 0.4 to 0.5 inches (10 to 13 mm) Petal count: 4 Color: White Other: flower arrangement, Cluster-spherical. Plant description: Erect Size: Typically 12 to 36 inches (30 - 91 cm), can reach up to 1.3 m (51 inches). Stem hairy: Glabrous or softly hairy in the basal region. Other: Smell of garlic. Leaf description: attachment is alternate, type is simple. Size: Leaves are approximately 5 to 8 cm long and a similar size wide. Color: Light to medium green. Hairy: Leaf surfaces can be glabrous or pilose. Other: Shape: leaf, (basal) reniform or cordate, (cauline) reniform or cordate (FNA). Origin (native, introduced, invasive): Introduced, ecologically invasive. On the resticted plant list for Wisconsin. Status (common, uncommon, threatened, rare): Very common in Putnam Park. Bloom time (typical): April to June Cycle (annual, biennial, perennial): Biennial. Habitat: Woodlands, roadsides, waste areas, streambanks, shade or part shade, moist to slightly dry. Fruit: A pod about 3 to 7 cm long and about 1 to 3 mm wide. Seed: Dark brown or black colored, about 2 to 5 mm long. Importance to wildlife: Similar species (if any): Some Cardamine species resemble Alliaria petiolata when it is in bloom. The latter species can be distinguished from the former species by crushing the leaves and detecting a garlic odor from A. petiolata and nothing from the Cardamine species. Also, the leaves of the Cardamine species are usually lobed, whereas the leaves of A. petiolata are not lobed. Ethnobotany: No Native American uses for Alliaria petiolata are recorded by (Moerman, 1998). This might be explained by the relatively late introduction of this species into the US in the mid nineteenth century.
