Verbascum thapsus: A
biennial herb originating in the 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 they 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. |
