Gallicas are shrubs that rarely grow over 4 feet (1.25 m) tall and flower once in Summer. Unlike most other once-blooming Old Garden Roses, gallicas include cultivars with flowers in hues of red, maroon, and purplish crimson. Examples include 'Cardinal de Richelieu', 'Charles de Mills', and 'Rosa Mundi' (R. gallica varietas versicolor).
