I was looking in my Field Guide to North American Wildflowers and there is one in there that the flower looks like it, however the picture in the book does not show the leaves. The name they gave for it was : Labrador Tea
(Ledum groenlandicum)Could this be the same?
Azalea: Some anise hyssop have white blooms and do not turn purple. However, this plant doesn't look exactly like anise hyssop to me, but is similar in some respects, particularly the anise scent to the leaves. Here a closeup of the white anise hyssop for you to compare: http://plantsdatabase.com/showpicture/9343/
