What is the central idea of the poem "Sea Rose" by H.D. (Hilda Doolittle)?

The rose gets stuck in the currents between the sea and the sand, making it less worthy.

The more traditional rose—the spice-rose—is most preferred to roses battered by sea and sand.

The sea rose's lack of petals, small leaves, and bitter smell make it unappealing.

The sea rose, even with its acrid scent, is more endearing than the traditional rose.
