Blue Potato Vine
HABIT: Often described as a "wall shrub," gets round & bushy, so It's best to prune it closer to the trellis every spring, taking care not to harm saved bits since these may be brittle. It grows rapidly & blooms profusely after such a trim.2” glossy dark green lance-shaped leaves, showy clusters of 1” blue, star-shaped flowers spring to fall followed by clusters of nail-polish red or yellow-orange berries late summer and fall.
CULTURE: full sun/light shade, moist, well drained, dormant in winter. Has to be annually trimmed back to the wall to retain a semblance of vining appearance. Pruning increases vigorous new growth & flower show.
USES: Colorful interesting vine
PROBLEMS: Few except the trimming needs.
NOTES: Plant is kin to Irish potato and deadly nightshade. Mildly toxic.
