The block is a different symmetry than the usual
Rose of Sharon patterns. Rather than 4-way
mirror-image symmetry the design is more of a bouquet.
Floral center with 4-way, mirror image symmetry,
a much more common pattern structure.
Marie Webster pictured the asymmetrical design in her 1916 book and
called it Rose of Sharon.
She called this one Virginia Rose
Here are a few variations of this asymmetrical rose design
from my Encyclopedia of Applique,
Rose of Sharon from Hall & Kretsingers' 1935 book.
Carrie Hall's block is in the collection of the Spencer Museum of Art.
International Quilt Study Center & Museum
Because the block is rather loose in structure
19th-century examples vary quite a bit.
Most of these photos are from online auctions or unattributed Pinterest posts
and most are mid-19th-century.
The major characteristic is a central rose or floral
with rotating motifs that are more like a bouquet
than the usual formal symmetries.
Here the central flower is a Victoria's Crown.
...a Harrison Rose.
Rose and pomegranate. The borders.....!!!
