Love the agapanthus this time of year.. They are a very photogenic flower.. Agapanthus do very well in NZ climate to the point that they can become a bit of a nuisance and they are not allowed to be sold in plant nurseries any more.
One if the first things I remember about first coming to NZ was the abundance of the Agapanthus growing everywhere. I love them. Yours is almost about to pop in fact I bet it has already!
