Hello lower mainland BC gardeners, A visiting researcher is looking for a large quantity of Lythrum salicaria, purple loosestrife. (Well, a kilo of dried leaf sounds like a lot to me.) I have asked around the garden and everyone knows of a few small patches in the local ditches, but no one seems to remember seeing a large patch. It's not in bloom yet, so not so easy to find right now. I would like to know if anyone remembers seeing a large quantity in bloom somewhere in the lower mainland (the closer to UBC the better). Thanks for any help on this.
