Verbena stricta (Hoary Vervain)
Available beginning May 19th…
Verbena stricta, commonly called hoary vervain, is a vigorous, clump-forming perennial that gets its common name from the white pubescence on its gray-green leaves and stems. It is a native Ontario plant occurring in prairies, glades, thickets, fields, waste ground and along railroads and roadsides. It grows in a narrow clump to 2-4’ tall and features blue-purple flowers (to 1/2” long) in narrow, upright, pencil-like, terminal panicles. Flowers are densely packed on the panicles, but bloom only a few at a time from bottom to top. Flowers appear from May to September, but primarily in summer. Ovate, coarsely-toothed, usually stalk-less leaves (to 4” long) are covered with whitish hairs. Foliage has a gray-green appearance.
