Perennial of the Geraniaceae family, Geranium x oxonianum is a hybrid between G. endressii and G. versicolor, two species from Southern Europe. 'Claridge Druce' is one of the oldest and most robust cultivars of this group, discovered in Oxford at the beginning of the 20th century and named in honor of the British botanist George Claridge Druce.
It forms large, vigorous, and spreading clumps, reaching 60 to 80 cm in height when in bloom, with a semi-upright then cascading habit. The foliage is palmately lobed, a strong green, slightly pubescent, persistent or semi-persistent depending on the climate, and serves as an effective ground cover even when not in bloom.
The flowers, about 3 cm in diameter, are medium pink to salmon pink, with dark pink to purplish veins finely drawn on each petal, a characteristic inherited from G. versicolor. The petals are slightly notched. The flowering is particularly long and sustained.
In cultivation, flowering extends from May until the first frosts, with a possible pause in midsummer during intense heat. A severe pruning during the season triggers a new wave of flowers and fresh foliage.
Very accommodating, it tolerates both full sun and partial shade, and adapts to ordinary soils, even dry ones. Its marked vigor makes it a subject to monitor in small spaces.
