Verbena – Rigida – 2 litre
Verbena rigida, or slender vervain, is a low-growing perennial species that produces an amazing non-stop show of strikingly bright purple flowers from summer and into autumn.
Its is not a tall plant – only growing to 30 cm and this means that this splendid little Verbena is great for planting in great swathes and softening the edges of borders. It will also self-seed, giving free seedlings and makes a great addition t0 sunny gravel gardens and wildlife gardens. From our point of view it is another generous perennial addition to feed the pollinators.
