Salvia nemorosa 'Sky Blue Marvel'

Extremely large (for a salvia), and long lasting sky blue spires of long lasting flowers over a very well branched plant make this bee and butterfly friendly perennial a garden must have.  

Preferring well drained but moist soil in decent sunlight, this hardy perennial makes a very striking addition to the herbaceous border, especially when planted en masse. 

Aromatic foliage 0.4m high by 0.3m spread
