Salvia patens ''Dwarf Patio Deep Blue''
This is a truly beautiful perennial with gorgeous electric blue flowers as per Salvia patens ''Blue Angel''. 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. Perfect in containers too. 30x30cm approximately.
