Agapanthus 'Underway'

A not often encountered deciduous Agapanthus which we have from the UK.  Flowers are a good mid-blue in bud, opening to a softer blue and impossible to overlook on stems 3'-4' tall.  Once this comes into flower, you know summer is well underway and time to get the garden parties started!  In colder zones, a good mulch over the crown to keep frost from reaching the crown is a good idea.
