Lobelia inflata, commonly known as Indian Tobacco or Puke Weed, is a small, annual herbaceous plant native to North America, particularly in the eastern United States and Canada. It typically grows to a height of 1 to 3 feet (30 to 90 cm) and features narrow, lance-shaped leaves and small, tubular flowers that are pale blue to lavender in color, with a distinctive white lower lip. Lobelia inflata is characterized by its inflated seed pods, which are the source of its common name. Annual
Germination
Germinating Lobelia inflata seeds can be a bit challenging due to their specific requirements. Begin by collecting mature seeds from the inflated seed pods, ensuring they are fully ripe. To enhance germination, stratify the seeds by placing them in a plastic bag with a damp paper towel or peat moss and refrigerate them for 2-4 weeks to mimic winter conditions. After stratification, sow the seeds in a seed tray or small pots filled with a well-draining seed-starting mix. Lightly press the seeds onto the surface of the soil; they require light for germination, so do not bury them. Maintain a temperature of around 65-70°F (18-21°C) and provide indirect light or grow lights. Keep the soil consistently moist but not waterlogged, using a fine mist to water the seeds to avoid dislodging them. Germination can be slow, taking several weeks to a few months. Once the seedlings have developed several true leaves, transplant them into individual pots or into the garden, ensuring they receive well-drained soil and partial shade. Lobelia inflata is a delicate plant, so handle the seedlings with care, and be patient, as successful germination may take time and attention.
