If you are looking to put some colour into your borders, we can recommend two beautiful plants that will flourish year after year.

Lavatera Ruby Star is a semi evergreen shrub with vibrant pink flowers.  Lavatera works well at the back of borders as it can grow quite tall and reasonably wide.

And Astilbe has fern like foliage and produces elegant plumes of pink of cream feathery flowers and dependant on the  size  of the Astilbe, it can work well in the middle or back of a border.
