I am a plant prized for my vibrant, trumpet-shaped blooms and ability to attract hummingbirds. My leaves are often glossy and dark green, and I thrive in warm climates. I am known to be toxic if ingested. What am I?

1. My flowers come in a wide range of colors, including red, pink, white, and yellow.
2. I am often used as an ornamental plant in gardens and landscapes in tropical regions.
3. Parts of me have been used traditionally for medicinal purposes, despite my toxicity.
4. I can be grown in pots or directly in the ground, but require well-drained soil.
