Description |
Hounds Tongue 1962 Cynoglossum officinale Invasive Species Houndstongue is a biennial forb that forms a deep tap root and basal rosette the first year. It forms a flowering stem in its second year. The rosette leaves are broad, oblong, petioled and resemble a dogs tongue in shape. Leaves are alternate, up to one foot in length and up to three inches wide. They have smooth margins and are soft and velvety to touch. In the second year, stems form and often branch at the top of the plant. Plants can grow up to four feet in height. Flowers are five petaled, reddish-purple in color and produce four triangular, rounded seeds. They typically bloom in June and July. Seeds are small brown nutlets about 1/3 inch in length that easily attach to animals, vehicles, and humans. The entire plant has soft white hairs on it. The single tap root of houndstongue is thick, black and woody. Houndstoungue reproduces from seed only and each plant can produce up to 2,000 seeds. The plant dies after its second year. Scanned |
