Its an Agapanthus (African Lily) pretty one Ross.

cheers i have a similar one in white is that the same . this one only has one head 2 years running the white one had 4 last year and 16 this year

Although they are usually blue or purple you can get white and pink ones Ross

They need a good baking the year before to flower well and they like to be packed tight. Perhaps your white one has more "company" and could be in a sunnier spot?

the white one is in a pot the blue in the ground that could be why . thanks for the feedbck peeps apreciate it
