Verbascum thapsus: A biennial
herb originating in Meditteranean Coast, it has been naturalized in
various parts of Japan, growing in dry riverbeds, wastelands, or
roadsides, with stems extending 1-2m in height. Hairs on stems or
leaves branch in a verticillate way, which characterizes this
species. Leaves on the lower parts are about 30cm long and
oblanceolate, and the upper part's leaves become smaller as to go
upward. Stem tips emerge 20-50cm long racemes and densely set yellow
flowers, and 2-2.5 cm-in-length corollas are cleft in five, with
stellate hairs outside. Bloom time: August-September. |
