The Rose of Sharon is a good name. This one by Charlotte Raynor
is in the Shelburne Museum's collection.
Democrat Rose from Marie Webster's 1915 book.
The pattern is one of the most popular appliques in the 1840-1880 period.
There are many example in my Encyclopedia of Applique, filed as 4+4 blocks
(Four motifs north/south axis---Four different repeats on the diagonal.)
One of the elements is a comb, a spiky shape.
The Encyclopedia of Applique number is 18
Spice Pink from Ruth Finley's 1929 book
Rebecca said No, and pointed out the center floral---“Conjoined cock’s combs." She wrote:
"I’ve been contemplating the differences. It almost seems as though this maker combined the 'rooster combs' of the Democratic rose into one blossom. Most of the Whig roses don’t have spiky but the more common rounded flower petal shapes."
She's right. I did a little digital altering of Charlotte Raynor's block
to show it with a circle of spiky points rather than 4 separate combs.
It took me a while to find other vintage quilts with the same construction, mainly because I was looking the 4+4 files. With one circular spiky shape in the center it's more like a #12.8xx
Center floral plus 4 identical arms.

There are not a lot of these spiky centers with the rotating arms.

Sometimes the difference is subtle between 4 combs or 1 circle.
Late 19th-century variation.
Guess based on the way the green has faded to tan.
Here's a real beauty. Source?
Rebecca wanted to know because she is working with a decorator at the Carlisle Inn in Sarasota Florida to name each floor after a quilt block pattern.
