Friday's roof garden plant additions

I received a few more plants on Friday and added them to the roof garden, in the hope of filling things in a little.  I put in a couple of gooseneck loosestrife:

Summersweet (Clethra alnifolia) "Sixteen Candles":

Siberian iris "Snow Queen":

More campanulas, this time Campanula glomerata alba:

and the groundcover Mazus reptans alba, currently looking very wilted in the red brick building's garden:

I also ordered three cold-hardy camellias, but they haven't shipped yet.  Curious to see whether they'll be okay up there.
