As you walk towards the Pavilions from the fountain end of the Broadwalk you cannot fail to notice on the left, Salvia uliginosa or ‘Bog sage’ with its electric clear sky-blue flowers. 

This is a robust, clump forming herbaceous perennial, preferring a south facing sheltered and sunny site with a reasonably rich moist soil, of which it would have traditionally been said, should not dry out in summer, however, it has survived this summer very well.
