Nightshade shrubs come into bloom in middle summer and persist till latest autumn.
The star-shaped flowers are pure white to light blue, with prominent yellow stamens. The flowers are followed by small purple-black berries, toxic if ingested.
Potato Vine is relatively frost-hardy, it can withstand cold temperatures down to about 17-21°F (-6°C to -8°C), and even lower.
Its evergreen leaves take a red tint during fall offering a spectacular view on fences and walls covered by Nightshade.
Another member of the Solanaceae Family is the Chinese lantern plant.
