Flowering

From Mid Summer TO Early Autumn

Tall spires of hooded blue flowers appear from mid Summer into Autumn

 

Planting

From Early Spring TO Mid Spring

Plant into rich and free-draining soil in a sunny or partially shady site. If the climate is hot the plant will need to be placed where there is shade from the mid-day sun.

 

Propagating by division

From Mid Autumn TO Late Autumn

Divide the rhizomes in Autumn. After approximately three years, once herbaceous perennial varieties have become established clumps they should be divided in order to retain vigour. The simplest method is to carefully dig around the clump and gently pull it apart into fist sized pieces and re-plant immediately. The middle of the original clump should be discarded as this will have lost vigour and become woody.
