Bell pepper 'California Wonder'

Sun

Full sun, ideally at least 6-8 hours daily; light afternoon shade can help in very hot climates.

Water

Keep the root zone evenly moist but not waterlogged; water deeply when the surface begins to dry.

Soil

Fertile, moisture-retentive but well-drained soil, ideally pH 6.0-7.0; use good-quality potting mix in containers.

Height

2-3 ft (0.6-0.9 m)

Spread

1.5-2 ft (0.45-0.6 m)

Flowers

Small white flowers from late spring through summer, continuing into autumn in warm conditions.

Foliage

Smooth, pointed, oval green leaves on branching, somewhat brittle stems.

Growth

Moderate; growth slows sharply in cool weather.

Growth rate

Slow

• Plant out after frost danger has passed, when nights are consistently above 55°F (13°C) and the soil has warmed.
• Space plants 18-24 in (45-60 cm) apart, or grow one plant in a container holding at least 5 US gallons (19 litres).
• Water at soil level and avoid repeated cycles of drought followed by soaking.
• Mulch once the soil is warm, keeping mulch clear of the stem.
• Feed container plants regularly with a tomato or vegetable fertiliser at the label rate; avoid excessive nitrogen.
• Use a short stake or small cage to support branches carrying heavy fruit.

Pruning. Routine pruning is unnecessary. Remove damaged or diseased growth promptly, and avoid stripping leaves that shade developing fruit.

Cut firm, full-sized, glossy green peppers once their walls feel substantial, usually about 70-80 days after transplanting in warm conditions. Leave them on the plant to turn fully red for a sweeter flavour; this often takes several additional weeks. Use scissors or secateurs, leaving a short stalk attached rather than pulling the fruit.

Late winter

Sow indoors about 8-10 weeks before your expected planting-out date; keep the seed mix around 75-85°F (24-29°C).

Early spring

Pot seedlings into individual containers and provide strong light and steady warmth.

Late spring

Harden plants off gradually, then transplant once frost risk has passed and nights are reliably warm.

Early summer

Install supports, mulch warm soil and begin regular feeding of container-grown plants.

Summer

Keep watering consistent, inspect leaf undersides for pests and harvest full-sized green peppers as needed.

Autumn

Pick remaining usable fruit before frost; remove plants when cropping ends and discard diseased material.

• Plant in orderly rows or blocks in a kitchen garden for accessible harvesting.
• Use in large patio containers alongside basil and parsley.
• Repeat through raised beds with lettuce or other low crops at the edges.
• Include in an edible border where the green-to-red fruit adds late-season colour.

Garden styles it suits: Potager (kitchen garden), Edible landscape, Homestead, Modern courtyard, Small-space and Family-friendly.

Plant it with: Basil, Parsley, Lettuce, Spring onions, French marigolds and Sweet alyssum.

Wildlife: Flowers are self-fertile but may also be visited by bees. Aphid-eating hoverfly larvae, lacewings and ladybirds can help control pests.

• Aphids and whiteflies: inspect young shoots and leaf undersides; dislodge aphids with water and use an approved insecticidal soap if necessary.
• Blossom-end rot: dark, sunken patches at the fruit base usually reflect disrupted calcium uptake; maintain even moisture and avoid excessive fertiliser rather than adding calcium without a soil test.
• Poor fruit set: cold nights or extreme heat can cause flowers to drop; provide warmth in cool climates and ventilation or light afternoon shade during heatwaves.
• Sunscald: pale, papery patches develop on exposed fruit; retain healthy foliage and provide light shade during intense heat.

Sweet bell pepper fruit is not known to be toxic to people, cats, dogs or horses. Large amounts may cause digestive upset, and whole fruits or tough stalks can present a choking risk to pets. Leaves and stems are not normally eaten; keep pets from chewing plants treated with garden chemicals.

• Other bell pepper varieties (Capsicum annuum)

  Many have almost identical leaves and blocky fruit. 'California Wonder' cannot be identified reliably from appearance alone; use a trustworthy seed or plant label.

• Chilli pepper (Capsicum annuum)

  Leaves and flowers can look identical, and some hot varieties have rounded fruit. Shape alone does not establish heat level; check the variety name.

The name 'bell pepper' refers to the broad, bell-like shape of the fruit, while annuum means 'annual' in Latin.

Propagation. Grow from seed, using warmth for germination. Seeds saved from fully red, ripe fruit can come true if flowers were not cross-pollinated by another pepper variety; crossing affects the next generation, not the sweetness of the current fruit.
