Malva Sylvestris Zebrina
One tough perennial! 'Zebrina' sports soft pink flowers with striking, raspberry-purple veins, achieving a pinwheel effect. These outstanding 2", bowl-shaped flowers are produced in abundance from early summer to frost on robust, shrub-like plants.
Heat and drought are not a problem for this perennial. Though it is sometimes short-lived, Malva will self-seed readily assuring years of blooms.
