Scotch Bonnet is one of the hottest chillies around, produces red chillies up to 4 cm long and is ideal for growing indoors on a window sill.
Chillies are perennial plants, and will go on producing for you for ages...
In the cooler months, keep warm enough and give as much light as possible, watering only when compost looks dry. A windowsill is fine in the day time - bring inside the curtains/blinds at night.
Can be grown on patio etc. in the summer.
Hand pollinate the flowers to ensure fruit forming.
