Don't have one myself but widely grown in the area. Convulvus is usually a climber so to have a bush habit is interesting. The silvery foliage is a nice addition to a garden. Evergreen too.

Dependable plant here in this part of the world... may even flower over winter.

This species of Convolvulus grows in the form of a "bush", growing to a height of 1' to 2'. Produces a long succession of flowers through spring and summer. Flowers are white with yellow throat. Best cultivated in sun in any moist well draining soil. Hardy zones 8-10.
