Langsdorff's Tobacco

Langsdorff's Tobacco (Nicotiana langsdorffii)

Langsdorff's Tobacco is a summer-blooming flowering tobacco that adds an airy, floating layer of color that feels fresh in mixed beds and containers. The lime-green, bell-shaped flowers mix easily with any palette and keep coming through the warm season, especially when plants are happy and well-watered. Its upright, branching habit fills space quickly, giving new plantings a more established look without heavy mass. It is also known as tobacco flower, and it is a strong choice when you want something a little unusual that still performs reliably.

Distinctive Features

This nicotiana produces nodding, tubular bell flowers in chartreuse to apple-lime tones from summer into fall, often continuing until frost in many climates. The stems branch freely and carry many blooms at once, creating a light, cloud-like effect rather than a dense block of color. Foliage is bold and often slightly sticky, adding a textured base that supports the tall flowering canopy. Plants can self-sow in favorable conditions, which can be a benefit if you want it to reappear year to year.

Growing Conditions

• Sun: Full sun to partial shade, with some afternoon shade helpful in hot climates.
• Soil: Moist but well-drained soil enriched with organic matter.
• Water: Medium, keep evenly moist for best growth and continuous flowering.
• USDA Zones: 10 to 11 as a tender perennial, typically grown as an annual outside this range.
• Mature Size: About 3 to 4 feet tall and 1.5 to 2 feet wide.
• Notable Traits: Lime-green flowers, long bloom season, attracts hummingbirds and pollinators, and all parts are toxic if ingested.

Ideal Uses

• Focal Point: Plant a small group behind lower growers so the lime-green bells become a midsummer focal point that reads as a soft glow.
• Mixed Borders: Use in the middle to back of beds to add height and an airy flowering layer without heaviness.
• Containers: Feature in large pots where the branching stems can create a full, upright centerpiece.
• Cut Flowers: Harvest stems for arrangements that need a unique color accent and light, dangling texture.
• Pollinator Plantings: Include to support hummingbirds and beneficial insects through the summer bloom window.

Low Maintenance Care

• Watering: Water consistently during establishment and hot weather to prevent stress and keep blooms coming.
• Feeding: Feed lightly during active growth, especially in containers, to support steady flowering.
• Staking: Stake in windy sites or rich soil if tall stems lean as the plant fills out.
• Deadheading: Remove tired stems if needed to refresh the plant and encourage new branching.
• Safety: Wear gloves if you are sensitive to sticky foliage and keep plant parts away from children and pets.
