Choose a plant that is the right height and color for your needs. Nicotiana grows anywhere from 12- to 36-inches tall in a variety of colors, including white, red, pink, cream, pale green and brown.
Consider fragrance. Modern hybrids stay open all day, but tend to be unscented. The unaltered species don't open until evening, but are beautifully fragrant.
Buy healthy, green plants with no signs of wilting or disease. Plants should be stocky with plenty of leaves. It's a plus if the plant doesn't have any flower since that means early energy will be diverted into root development.
Plant in spring after your region's last frost date. Nicotiana needs light shade to full sun in rich, well-drained soil, and thrives with a spadeful or two of compost worked into the soil.
Position plants 8- to 36-inches apart, depending on the type. Check the label for directions.
Keep well watered, especially when the weather is hot.
Fertilize regularly - every 3 to 4 weeks - or work in a slow-release fertilizer at planting time.
Discard plants once frost fells them in late fall.
