Salvia patens ''Blue Angel''
This is a truly beautiful perennial with the most stunning electric-blue flowers I have ever seen! I read a description once that the lower lip of the flower is ''a bee's landing pad'' which is just delightful! This treasure is very easy to grow, thriving in most soils in full sun or semi-shade. It's winter dormant and if you get harsh frosts it would be worth mulching the crown to protect it. 60-70x60cm approximately.
