Your plant is likely known as a Cineraria, but is really Pericallis x hybrida (also Senecio x hybrida ‘Senetti’), prized for its colorful flowers in shady areas or on a patio. Will grow 2 ft. tall and as wide with clusters of daisy-like flowers in a wide assortment of colors including your brilliant magenta and white specimen. Typically bloom in late winter or early spring. Does best in well-draining soil and although technically a perennial, most treat it like an annual. Will bloom again in summer if after the spring blooms are spent, the plant is cut back by about 50%. Primarily a cool-weather plant, it will stop blooming during intense summer heat. Needs to be kept moist, but not soggy, and is not considered a drought tolerant plant.
