CONVOLVULUS. Morning glory (See also Ipomoea). Widespread. We grow two very different members of this genus, both with funnel shaped blossoms flaring into broad saucers at the face. Sun or light shade, well drained, not-too-rich soil and moderate to little watering when established. Hardiness varies.
cneorum. Bush morning glory. A dense 2-4’ shrub with remarkably silvery leaves. It bears 2" white flowers from spring to fall. Hardy to 10-15oF.
mauritanicus. Ground morning glory. A perennial with slender, trailing stems lined by roundish grey green to dark green leaves. It bears many clusters of lavender 1½" blossoms at the branch tips in summer and fall. An attractive hanging basket plant or ground cover, hardy to around 10oF.
