Can you grow chilli plants from seeds?
Yes, although it may be a problem if the plants are from a hybrid variety. Seed can be started indoors and planted out when the danger of frost is over.
Seeds are a way that some plants reproduce. Those that do not use seeds for reproduction, do not need seeds. <><> They have other means of reproduction. Strawberry plants send out runners, which will root and form new plants. Potato plants grow potatoes, which sprout into new plants. Garlic and daffodils grow bulbs, which sprout new plants.
Many plants grow fruit as that is their way of propagating. The seeds are in the fruit, or around the fruit. The fruit serves as a sweet tissue surrounding the seeds to help the seeds travel and get planted and grow. Animals are likely to pick fruit, and in doing so, they help to disperse the seeds.
