This impressive climber makes a woody, evergreen perennial in its native Mexico. Here it grows 10ft or so over the summer and, from August until the first frosts, produces very large and distinctive flowers that begin a greenish-white but turn to an inky purple with age. The impressive big, graceful bells crowd for position on this super-fast, extra-showy twining vine. The bell-shaped flowers have a ruff of bracts - hence its common names, cup and saucer plant or cathedral bells.
Cobaea scandens will appeal to anyone who longs for something with panache and visual impact. Cobaea scandens can be grown in a large pot (at least in diameter) as long as suitable support is provided for it to cling to. They will overwinter provided that the temperature at night does not dip below freezing.
Other Names: cup-and-saucer vine, cathedral bells, Mexican ivy, or monastery bells, Mexican climbing cobaea, Purple vine, purple flowering vine
