A Summer Rose

Rock Rugosa Rose

The hardy rock rugosa rose* holds my heart since I was 8 years. Vacationing on Cape Cod, I saw them in a patch of neglected landscape. As I was weeding, I discovered there had been a circular garden there with a hand painted sign in the middle, Rexham Beach.

I look on the map to see if the garden is still there. Things changed so much, I can't tell where the cottage is with the garden across the street.
 

*A comment reveals the correct name is Rugosa Rose. Thank you Ivy

Crafting Signage

The sign is about a yard long by a foot high. A bunch of shells waiting for an idea, lines the top of the 3 glued and back braces nailed together boards, primed and painted with acrylics.

Strange that the rustic look, (hasn't been wear sanded yet), that I imagined now wants old weathered rope on the other 3 sides. 

There is an upholstery trim that will work called twisted lip cord. 

Light gray or blue? Sand looks ok, but white would be better.

Or should I paint and stress twigs or dowel trim to look like drift wood?

Opinions appreciated

Thank you
