Sasanquas are the beautiful autumn flowering Camellias. Their flowers are never very big and are mostly single or semi-double. They come in shades of red, pink and white, and most are slightly scented.
Sasanquas are more informally shaped than the Japonicas but are faster growing. It isn't necessary to prune a sasanqua unless you want to create a formal clipped hedge, in which case it is best to prune after the flowers are over.
Sasanquas can create a superb dense hedge which will flower every autumn. After the flowers have finished the plant produces interesting shiny black seeds (in Japan these are used to make Camellia oil and beads). The added advantage of the sasanqua is that they flower best in full sunshine, while other Camellias prefer some shade.
