A tall herbaceous perennial with erect, branching stems to 2m in height, bearing sparse, oblong leaves. Numerous branched clusters of small, lilac-purple flowers appear from summer to autumn; these are a good nectar source for pollinating insects.
Seeds can be sown directly in the ground in spring, or you can start them off under glass in late-winter, and plant them outside later. For best results grow Verbena bonariensis in full sun to partial shade, in moist but well-drained soil.
