SOME plants were born to have a starring role in our borders, while others were destined to be part of the supporting cast, not necessarily standing out, but there to help create a beautiful whole.

One such variety is Verbena bonariensis, a popular hardy perennial and this week's free seed.

Clusters of purple flowers bend and sway in the wind on tall willowy stems, lasting from midsummer right through to the autumn.
