Nicotiana (Flowering Tobacco) - Key Growing Information

Nicotiana in bloom on a research farm.

DAYS TO GERMINATION:

Seedlings appear in 7–14 days at 72–78°F (22–26°C).

SOWING:

Transplants are recommended: start seed 5–6 weeks ahead of planting out, using 72-cell flats. Press seed gently into the mix or barely cover it, as light helps germination. Harden off and plant out after the last frost. Pinching the main stem on young plants encourages branching. It germinates easily and flowers soon after planting out, giving several cuts through the season.

LIGHT PREFERENCE:

Full sun to partial shade.

PLANT SPACING:

Space plants 12–18" apart.

HARDINESS ZONES:

Grown as an annual.

VASE LIFE:

About 5–7 days.

HARVEST:

Cut once roughly half of the blooms on a stem are open. Stems strip easily but can leave a sticky film on hands and tools.

SOIL REQUIREMENTS:

Fertile soil with good drainage.

USES:

Cutting gardens, cottage gardens, beds and borders.
NOTES: Note that the plants contain nicotine.
