Sowing Instructions

Indoors: Sow seeds in trays or pots filled with moist, well-drained compost from February to April. Lightly press the seeds into the surface without covering them, as they need light to germinate. Maintain a temperature of 18-20°C. Transplant seedlings into individual pots when large enough to handle, and harden off before planting outdoors after the last frost.

 

Outdoors: Sow directly into prepared soil from April to May. Scatter seeds thinly on the soil surface and gently press them down. Keep moist until germination occurs. Thin seedlings to a spacing of 30 - 40 cm for healthy growth.

 

With its unique flower form and graceful height, Nicotiana langsdorffii is a superb choice for gardeners looking to add something distinctive and fragrant to their garden. Its long-lasting blooms and attraction to pollinators make it a valuable addition to any garden design.
