This image is a close-up of the petals of a Rose of Sharon. It was shot with the Canon 300L IS at 1/640 sec and f4.
The Rose of Sharon (Hibiscus syriacus) is not a rose, but a flowering shrub classified as deciduous. This means it will shed its leaves in the fall. It typically has white, light blue, lavender or in this case, red blooms.
The name, “rose of sharon” appears to have originated from the biblical Songs of Solomon (“I am the rose of Sharon, and the lilly of the valleys”).
