Must be an unusual variety of aggie.

If the original poster is asking what an agapanthus is . we can safely presume they aren't also aware of the official terminology of flower head arrangement can we.

Was the OP asking what an agapanthus is? I don't think so.
I didn't read it that way.
What I understood was that the OP was asking for an ID on a big plant either blue or white. grows like a weed, has a long stem and long leaves,with a spiked flower.
Read the whole thread & analyse where the aggie thing came in.
Not worth getting tetchy about, is it?

I'll go with Agapanthus too. Clincher being the bit about after the flower has finished the seeds are Black.
