Burley-B21 Nicotiana Seeds

Burley B-21 is a Nicotiana tabacum variety offered here as seed for growing the plant. The product card describes a robust, upright plant about 5 to 6 feet (1.5 to 1.8 m) tall, with broad, slightly puckered leaves that stay light green while they grow. The card also states resistance to wildfire, a bacterial leaf disease of Nicotiana. The notes below follow that description.

Burley B-21 is the name of this particular variety, and the store lists it as Nicotiana Burley-B21.

Growing Burley B-21 from seed

Nicotiana seed is very fine and needs light to germinate, so it is pressed onto the surface and never buried. The figures below come from the variety description and are approximate guides, not results measured on a specific seed lot.

• Sowing: press the seeds lightly onto the soil surface and leave them uncovered, because they need light for germination.
• Timing: start the seeds indoors 6 to 8 weeks before the last frost.
• Soil: well-drained, fertile soil with a pH between 6.0 and 7.0. Organic matter added to the bed supports growth.
• Light: full sunlight.
• Water: consistent watering, keeping the soil moist but not waterlogged.

Because the seed is so small, the surface layer can dry out quickly. Water gently, from below or with a fine mist, so the seeds stay in place on the soil instead of washing together into clumps. Once the seedlings have grown their first true leaves, thinning them gives each plant room before it goes outdoors.

Space and site planning

A plant that reaches 5 to 6 feet and carries leaves up to 24 inches long needs room for air to move around it and for each leaf to open fully. The product card does not give a plant spacing, so plan the bed with the finished size in mind rather than the size of a seedling. A sunny position with fertile, free-draining soil matches the variety description.

What is not yet recorded

No seed specifications have been saved for this variety yet. For that reason this page does not state a germination percentage, a viability period, a germination temperature or a seed size. The origin of the variety, its breeding history and its days to flowering are also not documented on the product card, so they are left out here rather than guessed. Photographs in the gallery have not been reviewed against this variety, so this text makes no claims about what the plants in them look like beyond the card.

FAQ

How do I sow Burley B-21 seeds?

Press them lightly onto the surface of moist, well-drained soil and do not cover them. The seeds need light to germinate, so burying them works against the plant. Keep the surface evenly moist but never waterlogged.

When should I sow Burley B-21?

The variety description recommends sowing indoors 6 to 8 weeks before the last frost in your area. Seedlings move outdoors into full sun once the weather has settled. The card gives no germination time, so check the tray regularly instead of judging it on a fixed date.

How tall does Burley B-21 grow?

The product card gives a height of about 5 to 6 feet (1.5 to 1.8 m), with broad, slightly puckered leaves up to 24 inches long and 12 inches wide. Treat these as approximate figures, since light, soil and spacing change the final size.
