Double-Flowered Rose of Sharon

I've been quite keen on photographing examples of Rose of Sharon because it was my favorite flower when I was my daughter's age, living in Indianapolis in 1976, back when so many gents had apostolic hairdos and most everyone shared the guilt of poor fashion. Back then, I adored the single-flowered Rose of Sharon, the ones bearing white or purple blooms with red, satin centers. Alas, I have not yet gotten out to the local park where the classic varieties are close enough for a macro shot.
