Stachys officinalis rosea

This Stachys is nothing like lambs ears in appearance or habit. Deep green crinkled leaves and pink flowers held way above its foliage in early summer. This is a clumping perennial, while it makes large clumps it does not spread. I grow it in full sun but would be better growing in partial shade in lowland gardens.
The flowers are 25cm while foliage is around 15cm.
