Generally not harvested.
Sow seeds as soon as they are ripe into modules or small pots. Over winter in a sheltered location, such as a cold frame. Seeds should germinate in spring. Alternatively, stratify the seeds by folding them into a damp piece of kitchen towel inside a seal-able plastic bag. Place in the refrigerator for 3 months, checking regularly to ensure the towel stays moist and remove any seeds which begin to germinate. These can be planted up and grown on partial sunlight and slowly warming conditions.
