Description

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Tolerates full shade, but best flower production occurs in sun. Prune after flowering if needed. Above ground stems are not reliably winter hardy throughout USDA Zone 5 where they may die to the ground in severe winters (roots are usually hardy therein and will sprout new growth the following spring). In St. Louis, it is best to plant this vine in a protected location and apply a winter mulch. Established plants may send up root suckers which should be removed if spread is not desired.
