This is a showy, evergreen, slender-stemmed vine growing to 20 ft (6 m) and bearing large nodding clusters of violet-blue flowers with yellow stamens in summer. These are followed by small scarlet berries. Very tender to cool weather. Prefers artial shade, especially in afternoon. In tropical climates, use for year-long coverage of arbors, gazebos, and trellises, even the clear trunk of a palm or other tree: anywhere a vine is desirable. The Solanum family is very large, consisting of nearly 1500 species ranging from vegetables like the potato and aubergine, to ornamental shrubs and climbers, plus a number of weeds. Some, as their common name Nightshade suggests, are toxic and need careful handling.

Solanum sisymbriifolium, Solanum balbisii

Solanum sisymbriifolium, commonly known as Sticky Nightshade, is a small plant native to South America. It is known for its irritating, prickly foliage and bright, colorful flowers. It can grow as tall as 2-5 feet, depending on how it is cared for.

The Sticky Nightshade thrives in full or semi-shade sunlight, and it requires regular to moderate water. When it is in bloom, it produces a variety of flower colors, including pink, white, off-white, blue, lavender, and purple. All of the flowers have the same basic shape, each with five petals and a yellow center.

When caring for this plant in a pot, it should be given special attention in cold regions. The mature plant is known to be cold hardy at least to 30s F for a short time. If the temperature drops below this level, the plants should be brought indoors until the weather warms back up.

The Sticky Nightshade is also known for its edible fruits which are often used in cooking, although it does produce irritating sap when handled. These small and round fruits are red on the outside with a yellow center that bursts open when ripe and fully ready to be harvested. It is known to produce over a hundred of these fruits in a single season, and they are known to contain vitamins A and C along with other healthy benefits.

In conclusion, the Sticky Nightshade is a small, vibrant plant that is native to South America. It's easy to care for, producing an abundance of colorful flowers and edible fruits. It requires regular to moderate water and semi-shade sunlight, and in cold regions, it should be brought inside during extreme temperatures to ensure it is not damaged.
