Agapanthus campanulatus 'Albus' (White African or White Nile Lily)
Michael's Opinion
This is a wonderful bulb, where I have seen it growing en masse naturalized in the dunes on Tresco Island off the coast of Cornwall, England. It is now harvested on Tresco as a cut-flower and shipped to markets in London on the same day. Although it is not supposed to be hardy in our zone 5 (USDA) garden we have had it flower (white form) for the past four years near a corner of the house under heavy mulch. For those not so fortunate an attempt at growing it in large pots is worth the effort.
