Black-Eyed Susan vs Jasmine Tobacco Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Black-Eyed Susan
Rudbeckia hirta
Rudbeckia hirta, commonly known as Black-Eyed Susan, is a flowering plant typically grown as an annual or short-lived perennial. It features daisy-like flowers with bright yellow petals surrounding a dark brown or black central cone. The plant grows upright, reaching heights of 1 to 3 feet. It is primarily an outdoor plant, valued for its vibrant blooms and ability to attract pollinators to gardens. While technically possible to grow indoors, it requires very specific and intense lighting conditions to thrive and bloom, making it challenging.
Jasmine Tobacco
Nicotiana alata
Nicotiana alata, commonly known as Jasmine Tobacco, is a tender perennial often grown as an annual. It features a basal rosette of large, oval leaves from which tall, slender stalks emerge, bearing clusters of trumpet-shaped, fragrant flowers. The flowers are typically white but can also be found in shades of pink, red, and lime green. It's primarily grown outdoors for its evening fragrance and attractive blooms, which attract pollinators. While it can be grown indoors, providing sufficient light and humidity is challenging, making it more suitable for outdoor gardens.

Water regularly, especially during dry periods, but avoid overwatering. Fertilize sparingly with a balanced fertilizer in the spring to encourage blooming. Deadhead spent flowers to promote continuous blooming throughout the season.
How do I propagate Black-Eyed Susan?
Black-Eyed Susans can be propagated through division or seeds.
Jasmine Tobacco
What are the light requirements for Jasmine Tobacco?
Jasmine Tobacco requires a good amount of light to thrive and produce abundant blooms. Aim for at least 6 hours of direct sunlight per day, ideally in the morning or late afternoon. In hotter climates, providing some afternoon shade can prevent leaf scorch. If grown indoors, place the plant near a sunny window, such as a south-facing or west-facing window.
How do I care for Jasmine Tobacco?
