Growing it
- Propagation
- seed
- When to plant
- Spring
- Overwintering
- This plant is typically grown as an annual and will die back with the first frost. You can collect seeds in late autumn to sow again the following spring.
- In containers
- It grows well in containers, provided you use a pot at least 30 centimeters in diameter to support its large root system.
Seed
- 1. Surface sow the tiny seeds in a seed starting tray.
- 2. Keep the soil moist and in a warm, bright location.
- 3. Transplant seedlings once they have two sets of true leaves.
Planting aromatic herbs nearby can help confuse pests looking for the large, soft leaves.
Grows well with
- Marigold — They help deter soil nematodes that can affect the roots.
- Basil — The strong scent of basil can help mask the plant from certain pests.
Keep away from
- Tomato — They share similar pests and diseases which can spread rapidly between them.
Similar species
- Flowering Tobacco — Often grown for its fragrant flowers rather than its foliage.
