S. dunnii is the source of all of the red color in hybrid Streptocarpus. Its single leaf is particularly distinctive due to its usual grayish-green tone. Note the “abscission zone”, the portion of the leaf that has died off. The ability to jettison a portion of the leaf allows the plant to survive dry seasons by reducing the amount of surface area subject to transpiration of water.
