Verbena 'Polaris'
A low spreading ground cover with masses of silvery-lilac flowers displayed for months. Ideal for smothering weeds, plant amongst perennials or allow to scramble under shrubs. Withstanding dry, sun scorched and windswept conditions, this vervain is as tough as it is beautiful, thriving in parched and tired soils.
How to grow
Withstands hot and dry conditions, poor soils and windswept or coastal positions. Water and fertilise only as required. Prune to the ground (basal rosette) after flowering finishes in autumn. Readily self seeds.
