Bignonia Argyro violacea (Cross Vine) 4”

Bignonia argyroviolacea (commonly called Violet Trumpet Vine) can be a stunning and rewarding indoor plant when given the right conditions. Known for its cascading, trumpet-shaped flowers in rich violet and silvery-lavender tones, this tropical vine brings a bold burst of color and elegance to interior spaces. As a young 4-inch plant, it establishes quickly, forming lush green foliage that trails gracefully from pots or climbs supports. Native to South America’s tropical forests, it naturally grows under filtered sunlight and high humidity both of which can be recreated indoors with a bit of care and attention.

When grown inside, the Violet Trumpet Vine prefers bright, indirect light to thrive. An east-facing window offers ideal conditions with gentle morning sun, or it can be placed a few feet back from a south or west window where the light is filtered through sheer curtains. Avoid harsh, direct sunlight that can scorch its tender leaves. The plant enjoys warm household temperatures (65–80°F) and consistent humidity around 50–70% a nearby humidifier, pebble tray, or regular misting helps mimic its tropical environment. Keep the soil light and well-draining, and water when the top inch begins to dry, ensuring the roots never sit in soggy soil.

Indoors, Bignonia argyroviolacea grows beautifully when trained on a small trellis, moss pole, or hanging basket where its vines can spill over naturally. Fertilize monthly during spring and summer with a balanced liquid fertilizer to encourage healthy growth and blooming. With the right care, this vine rewards you with lush greenery and clusters of soft, violet flowers that bring a touch of the tropics inside year-round. It’s a perfect statement piece for bright rooms, sunrooms, or plant displays needing color and soft texture.
