Wanted: Gooseneck loosestrife

I am looking for a few starts of this for postage if possible. I want to try to hide one of those ugly green electrical boxes in my yard and I think this will do the trick nicely :)

comprey works well also.....

but I do have Yellow Loosestrife or Variegated Yellow 'Alexander'....both reaches just over 2'
and a Variegated taller variety with purple flowers....reaches around 3 1/2- 4'

I would be interested in the purple flowering one if that's ok :) I'll have to look up comprey.
