Verbena brasiliensis,
a perennial herb native to South America, grows wild in sunny
grasslands, bare areas, or gravelly soil. 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 the upper halves. Stem tips produce 2-3cm-long
pikes that branch and set many flowers, including corollas that are
3 mm across and light blue-purple. During fruiting, the spikes
elongate into cylindrical structures. Bloom time: June-September. |
