Verbena Bonariensis perennial plant
When it comes to popular perennial plants this one has got to be in the running for first place.
This is one of the taller Verbena varieties and can grow as high as 1.5m with the flowers.
The flowers really are the star of the show and have a lovely purple colour to the late spring until the Autumn. As well as looking good in the garden it also grows well in a large pot which can be left outside all year round as this is nice and hardy.
