Tobacco (Nicotiana excelsior): A Mysterious Member of the Nightshade Family
If you’ve stumbled across the name Nicotiana excelsior in your gardening research, you’re not alone in wondering what exactly this plant is all about. This particular species of tobacco is quite the botanical mystery, with very little reliable information available in standard horticultural references.
What We Know About This Tobacco Species
Nicotiana excelsior belongs to the tobacco genus, which is part of the nightshade family (Solanaceae). While the genus Nicotiana includes many well-known species like ornamental flowering tobacco and commercial tobacco, this particular species remains poorly documented in mainstream gardening and botanical literature.
The common name tobacco links it to its more famous relatives, but without reliable documentation, we can’t make specific claims about its appearance, growing habits, or garden performance.
The Challenge with Rare or Undocumented Species
Here’s where things get tricky for gardeners: when a plant species has limited documentation, it becomes nearly impossible to provide reliable growing advice. We don’t have confirmed information about:
- Its native range or geographical distribution
- Preferred growing conditions
- Hardiness zones
- Mature size and growth habits
- Pollinator or wildlife benefits
- Invasive potential
Should You Grow Nicotiana excelsior?
Without reliable information about this species, it’s difficult to recommend for or against growing it. If you’ve encountered seeds or plants labeled as Nicotiana excelsior, proceed with caution and consider these alternatives:
Better-Documented Tobacco Alternatives
Instead of gambling on an unknown species, consider these well-documented members of the Nicotiana genus:
- Nicotiana alata (Flowering Tobacco) – Fragrant evening blooms, easy to grow annual
- Nicotiana sylvestris (Woodland Tobacco) – Tall, dramatic white flowers, great for back borders
- Nicotiana langsdorffii – Unusual lime-green flowers, interesting for cottage gardens
If You’re Determined to Try It
Should you decide to experiment with Nicotiana excelsior despite the lack of information, treat it like other tobacco species as a starting point:
- Start seeds indoors 6-8 weeks before last frost
- Provide well-draining soil in full sun to partial shade
- Keep soil consistently moist but not waterlogged
- Monitor closely for any aggressive spreading or self-seeding
The Bottom Line
While botanical mysteries can be intriguing, they’re not always the best choice for your garden. Without reliable information about Nicotiana excelsior’s growing requirements, potential benefits, or possible invasiveness, you’re essentially conducting a gardening experiment with unknown results.
For a more predictable and rewarding gardening experience, stick with the well-documented tobacco species that offer proven beauty, fragrance, and pollinator appeal. Your garden (and your sanity) will thank you for choosing plants with established track records!
