Cobaea scandens, the cup-and-saucer vine, cathedral bells, Mexican ivy, or monastery bells, is a species of flowering perennial plant of the Polemoniaceae family, native to the tropical Americas.

It is widely cultivated for its twining habit and its highly ornamental, bell-shaped flowers, 5 cm (2 in) long, which change from white to purple. It is not hardy, and requires protection from winter frost and winds.[1] It has gained the Royal Horticultural Society's Award of Garden Merit[2] (confirmed 2017).[3] A white form exists, C. scandens f. alba.[4]

This plant has become a common weed in New Zealand, probably as a garden escape.
