Capsicum annuum 'California Wonder'
California Wonder Bell Pepper
Cultivar developed in California, USA (1928); the species C. annuum is native to Central America and MexicoOverview
Capsicum annuum 'California Wonder' is California Wonder bell pepper, a determinate annual growing 18-24 inches (45-60 cm) tall and 15-18 inches (38-45 cm) wide. Large blocky 4-lobed bell peppers 4-4.5 inches (10-11 cm) long and 3.5-4 inches (9-10 cm) wide with thick walls — green when immature, ripening to red if left on the plant (additional 2-3 weeks after green maturity). White 5-petaled star-shaped flowers at leaf axils. In the nightshade family (Solanaceae). The standard open-pollinated bell pepper cultivar since 1928. Zero Scoville heat units — a sweet pepper with no capsaicin. Determinate growth (the plant reaches a fixed size). Flowers drop without setting fruit when night temperatures exceed 80°F (27°C) or drop below 55°F (13°C). Start indoors 8 weeks before last frost — peppers require a longer indoor start than tomatoes. Fruit matures in 70-80 days from transplant (green stage). Consistent moisture and warm soil temperatures. Leaves and stems contain solanine — mild toxicity. Ripe fruit is non-toxic. Full sun (6+ hours). Tender annual. Growth rate is moderate.
