Verbena brasiliensis, a
perennial herb in South America, grows wild in sunny grassland, bare
lands, or gravelly soil areas. With four ridges, stems stand erect
and branch well, nodding to approximately 1.5m height. On-stem
leaves, with no petioles, are opposite, broadly linear, with sharp
serrations on upper halves. Stem tips give 2-3cm-long pikes that
branch and set many flowers in them: corollas, 3mm-across, light
blue-purple. In fruiting time, the spikes grow long to become
cylindrical. Bloom time: June-September. |
