long-flowered tobacco plant


Nicotiana longiflora, commonly known as long-flowered tobacco, is a species of plant that is notable for its dramatic and attractive blossoms. The appearance of this plant is characterized by large, tubular flowers that are particularly elongated, hence the name "longiflora." These flowers are usually white and give off a sweet, intense fragrance, especially in the evening. The plant has a lush arrangement of leaves, which are typically broad, pointed, and a deep green in color, providing a verdant backdrop to the striking flowers. The overall shape of the plant is somewhat bushy, with a well-branched structure that supports the weight of the blooms. The blooms themselves are arranged in loose clusters at the tips of the branches, creating a visually appealing display. Despite avoiding the mention of precise measurements, the long-flowered tobacco is recognized for having a significant floral presence.

  • water dropWater

    The most common common name for Nicotiana longiflora is Jasmine Tobacco. It should be watered regularly to keep the soil evenly moist but not soggy. During the active growing season in spring and summer, water Jasmine Tobacco when the top inch of soil feels dry, typically once every 2 or 3 days, but this can vary based on temperature and humidity. In terms of amount, approximately half a gallon per week for a medium-sized plant is sufficient. Cut back on watering in the fall and winter months to prevent overwatering as growth slows.

  • sunLight

    Jasmine Tobacco thrives in full sun to partial shade, with at least six hours of direct sunlight a day being ideal. The best spot for this plant would be where it can receive ample morning sunlight while being shielded from the harshest afternoon rays, especially in hot climates.

  • thermometerTemperature

    Jasmine Tobacco prefers warm conditions and does well in temperatures between 60 and 75 degrees Fahrenheit. It should not be exposed to temperatures below 50 degrees Fahrenheit to avoid cold damage. The ideal temperature range for vigorous growth is right in the middle of its tolerance levels.

  • scissorsPruning

    Pruning Jasmine Tobacco is primarily done to encourage fuller growth and maintain an attractive shape. Pinch off the tips of young plants to promote branching. Deadheading spent flowers can also stimulate new blooms. The best time to prune heavily is in late winter or early spring, before new growth begins.

  • circleLife cycle

    Nicotiana longiflora, commonly known as Long-Flowered Tobacco, begins its life cycle when its seeds germinate in warm, moist soil. The seedlings grow into leafy plants with a robust root system, and as they mature, they form a rosette of large, sticky, green leaves. The plant then develops a tall stem which produces tubular, fragrant white flowers that open at night, attracting pollinators such as moths. After pollination, these flowers develop into capsules containing numerous tiny seeds. Once mature, the seed capsules split open, dispersing seeds that can give rise to new plants. This cycle can occur multiple times in a year depending on growing conditions.

      Spring to summer

    • Nicotiana longiflora, commonly known as long-flowered tobacco, is typically propagated through seeds. The most popular method involves sowing the seeds indoors about 6 to 8 weeks before the last expected frost. Fill a container with a well-draining seed starting mix, sprinkle the tiny seeds on the surface, and lightly press them into the soil without covering them, as they need light to germinate. Keep the soil consistently moist by misting it lightly with water, maintaining a temperature around 70°F (approximately 21°C). Seedlings usually emerge within 10 to 14 days and can be transplanted outdoors once the danger of frost has passed and seedlings have grown strong enough. Thin them to stand about 12 to 18 inches apart (30 to 45 centimeters) to allow ample space for growth.
