I grew this from seed of the deciduous Agapanthus (more narrow leaves) obtained from the RHS Seed Programme. Mine are white and mid-blue varieties and I have had them for about 20 years in various parts of my Zone 4b garden. They are happier now in much more sun, even though they face the prevailing weather, and I do nothing more than give each clump a little mulch for the winter, pulling it off in the Spring.
