What is an ornamental pepper?
Ornamental peppers are compact pepper plants (usually Capsicum annuum) bred for the look of their small, upright fruit, which ripens through colors such as purple, yellow, orange and red, often with several colors on one plant at once. They are sold in autumn and holiday displays as short-lived plants. Treat them as seasonal, colorful plants rather than permanent houseplants, although with good light some can be kept going for longer.
Ornamental peppers are sold for decoration, not for eating, so read the next-to-last section on safety before you buy one for a home with pets or children.
Is it hard to grow indoors?
Ornamental peppers are fairly easy to keep looking good for a few weeks to months, and more demanding to keep growing and fruiting for the long term indoors. The main limit is light. A very bright window or a grow light is needed to keep leaves healthy and fruit coming, and dry heated air and irregular watering shorten the plant’s life. If you are happy to enjoy the fruit for one season, the plant is straightforward. If you want to keep it for years, the care is closer to that of a hobby crop.
Do ornamental peppers like sun?
Yes. They are sun-loving plants and need as much bright light as you can give them. A south-facing window is usually best, and many growers suggest at least six hours of strong light a day, or supplemental light from a grow light. In low light, plants get leggy, drop leaves and drop flowers, and the fruit may fail to develop. If you move a plant from shade into strong light, adjust gradually to avoid leaf scorch.
Watering, soil and feeding
- Water: Keep the mix evenly moist, watering when the top inch or so is dry. Let excess water drain. Pepper plants wilt quickly if they dry out completely, and constant soggy conditions encourage root rot.
- Soil: A general-purpose, well-draining potting mix in a pot with drainage holes.
- Feeding: While the plant is growing and flowering, a diluted balanced or bloom-oriented fertilizer every few weeks can help. Overfeeding with nitrogen may produce leaves at the expense of flowers.
- Temperature: Warm room temperatures are best. Avoid cold drafts and sudden changes.
Flowers, fruit and pollination
Ornamental peppers produce small white or pale flowers that develop into fruit. Pepper flowers are generally self-pollinating, but indoors there is no wind or insects to move the pollen. Gently tapping the stems or flicking the flowers, or touching them with a soft brush, can help fruit set. Flowers drop when the plant is stressed by low light, dry air, heat extremes or irregular watering.
Fruit usually changes color as it ripens, and many types look best when they carry fruit at several stages at once.
Do ornamental peppers need support?
Most compact varieties sold as ornamentals are bushy and don’t need staking. If a branch is heavy with fruit or the plant is leaning, a small stake or loose tie can prevent it from snapping. Rotate the pot occasionally so growth stays balanced toward the light.
Pests and problems
- Aphids, whiteflies and spider mites: Common on indoor pepper plants, especially in dry air. Check leaf undersides regularly, rinse or wipe the foliage, and follow product directions if you use a treatment.
- Leaf drop: Often caused by cold, low light, underwatering or overwatering, or sudden environmental changes.
- Flower or fruit drop: Stress from heat, low light or irregular watering.
- Yellow leaves: Overwatering, poor drainage or nutrient shortage.
Winter and lifespan
Many ornamental peppers are treated as annuals, and they often decline after a heavy fruiting period. In a bright, warm spot, some plants can be kept through winter and will fruit again, but results vary. If the plant is looking tired, you can prune it lightly, keep watering modestly, and give it as much light as possible until spring. Be realistic: many people enjoy a plant for one season and replace it.
Safety: pets, children and hot fruit
Ornamental pepper fruit can be hot and irritating, and the plant belongs to the nightshade family. It is generally listed as potentially harmful to pets, and the fruit and leaves should not be eaten. The bright, shiny fruit may look tempting to children and animals. Eating it may cause mouth burning and stomach upset, and juice can irritate skin and eyes.
- Keep the plant well out of reach of children, cats and dogs.
- Do not assume the fruit is a safe cooking pepper. Ornamental varieties are not bred for the table, and some can be very hot.
- Wash your hands after handling the fruit, and avoid touching your face or eyes.
- If a child or pet eats any, contact a veterinarian, doctor or poison control service.
