A gorgeous, very hardy perennial that deserves a spot in every garden. Forms a stunning clump of green heart-shaped leaves topped with tall steely blue stems (stunning in their own right!) of blue flowers. The flowers start off green and then slowly change to blue giving a lovely two-tone effect. Perfect as a cut or dried flower. Cut stems down after flowering. Most soils, sun, good drainage. Semi-evergreen. 1mx75cm approximately.
