Nicotiana, or flowering tobacco, is cherished for its beauty and longevity in summer gardens. Originating from Central and South America, various species of nicotiana have been utilized in tobacco production for centuries.
As a passionate gardener, I've cultivated numerous varieties of nicotiana—not for tobacco, but because these cottage garden favorites truly shine in borders. They typically bloom from June until October, bringing consistent interest to the garden as summer reaches its peak.
Previously, I grew Nicotiana sylvestris, known for its striking white trumpet-shaped flowers, which are among the most fragrant flowers. If you're a gardener who enjoys nighttime blooms, this species is particularly appealing as it attracts moths. My personal favorite, however, is Nicotiana 'Lime Green', seen in the image above, boasting vibrant lemon-lime blooms that are visually stunning both in the garden and in a vase. Here, I'll share my top three tips for successfully growing nicotiana based on expert advice.
How to Cultivate and Care for Nicotiana
Nicotiana thrives in full sunlight and high humidity, flourishing in tropical regions like Brazil, Colombia, and Argentina. If you're in USDA hardiness zone 10 or warmer, you can grow nicotiana as a perennial. However, in cooler areas, these flowering plants are often treated as annuals, blooming throughout the summer until the frost arrives.
1. Extend Flowering by Deadheading Nicotiana
According to gardening expert Gail Pabst, 'Flowering tobacco plants are known for their long-lasting blooms.' These plants can flower from June until the frost, making them standout late summer flowers that are sure to impress.
To maintain their floral display, deadheading—removing spent blooms—is vital for both annuals and perennials. Whether your nicotiana is in borders or pots, this practice will significantly boost the number of flowers each plant produces.
Gail emphasizes, 'If you want to maximize flowering, deadheading is essential.' This involves removing each stem after the flowers have faded. I recommend using your hands to gently pinch off wilting or brown flowers, as shown in the image above. After the blooms are finished, use pruning snips to cut down to a leaf node.
For optimal results, aim to deadhead every 2 to 3 days during the spring and summer months. Spending a little time each evening on this task can be a relaxing way to keep your plants blooming.
A common mistake to avoid while deadheading is using inappropriate tools. Large shears aren't necessary; small pruning snips, available at Walmart, are perfect for the job.
2. Fertilizing Nicotiana for a Healthier Boost
Maintaining healthy soil is crucial for successful gardening, and ensuring your plants receive the nutrients they need to thrive is essential. While some plants can flourish without fertilizer, nicotiana benefits from feeding during the summer months. Be sure to add this annual to your fertilizing schedule in July.
Gail mentions, 'For gardeners looking to attract pollinators, nicotiana is an outstanding choice.' These flowering tobacco plants draw in hummingbirds, butterflies, and moths, so it's important to provide them with the nutrients they need for healthy blooms.
'If your soil quality is low, fertilizing nicotiana is a good idea,' she adds. 'These flowers thrive in nutrient-rich soil, which will enhance their health and flowering capacity.'
If growing nicotiana in containers, opt for high-quality organic potting soil, available on Amazon. This will supply your plants with the necessary nutrients.
Bloom booster fertilizers can also be beneficial for flowering plants, ensuring they receive the nourishment needed to flourish throughout summer.
3. Keep Nicotiana Away from Other Nightshade Plants
Gail points out, 'Nicotiana belongs to the nightshade family, Solanaceae, which includes tomatoes, eggplants, potatoes, and peppers.'
'While these plants are generally free from pests, they can be susceptible to the Tobacco Mosaic Virus,' she warns. This virus can harm any member of the Solanaceae family, causing leaf discoloration and drop.
'It's best to avoid planting nicotiana near your vegetable garden,' Gail advises. 'This virus spreads easily, so keep nightshade family plants separate to ensure their health.'
You can find organic pest sprays on Amazon.
White flowering tobacco plants, Nicotiana Alata, can create a stunning impact in your garden. With their star-shaped white flowers, these plants can thrive in pots or be planted directly in the soil.
FAQs
Is Nicotiana an Annual or a Perennial?
Nicotiana plants are generally treated as annuals, blooming throughout summer until the first frost in the fall. In warmer regions, such as US hardiness zone 9 and above, they can be grown as short-lived perennials, lasting 2 to 3 years. Understanding how to cultivate nicotiana is essential, and propagating new plants each year is advisable.
With their striking flowers, nicotiana can brighten your garden for much of the growing season. By following these three tips, your plants will flourish and provide vibrant color to your outdoor space.
