This past July I was hiking along a huge cliff near Hole In The Wall on
Grand Manan Island of the coast of New Brunswick - this was the only
plant growing on - out of - the rock, I was amaized by its ability to
grow under such adverse conditions, but I can not find out what it is -

Any help identifying this plant would be welcome.

Thank you.
