Caradonna Sage has masses of beautiful spikes of royal blue flowers rising above the foliage from late spring to early summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its fragrant narrow leaves remain green in color throughout the season. The fruit is not ornamentally significant. The burgundy stems are very colorful and add to the overall interest of the plant.
