Cobaea scandens ~ Cup and Saucer Vine
Cobaea scandens is often grown as an annual, but in frost free or nearly frost free locations it grows quite nicely as a long lived vine. The soft tendrils of Cobaea scandens are easily pulled out of the neighboring shrubbery, though it will travel quite a distance if left unchecked. The dark purple flowers of Cobaea scandens are more than 2" across and are produced all year long unless the plants are damaged. I have had good luck with these in lightly shaded sections of the garden. Cobaea scandens has low to moderate water needs.
