Overview
Capsicum annuum 'Jalapeño' is a compact, bushy annual pepper plant that typically grows 24-36 inches tall and 18-24 inches wide. The plant features dark green, oval-shaped leaves with smooth margins and a slightly glossy texture. Small white flowers appear in clusters along the stems, giving way to the characteristic cone-shaped fruits that are initially dark green and mature to bright red if left on the plant. The peppers are typically 2-4 inches long with thick walls and a tapered end, offering a moderate heat level of 2,500-8,000 Scoville units. This cultivar is distinguished from other Capsicum annuum varieties by its specific fruit size, shape, and heat level, making it one of the most recognizable and widely grown hot pepper varieties.
Native Range
Capsicum annuum is native to Central and South America, particularly the regions of Mexico and northern Guatemala, where wild ancestors still grow naturally in tropical and subtropical areas.Suggested Uses

Care & Maintenance
Care Guide
Capsicum annuum 'Jalapeño' requires consistent moisture throughout the growing season, with soil kept evenly moist but not waterlogged. Water deeply 1-2 times per week, providing about 1 inch of water weekly. Fertilize every 2-3 weeks with a balanced fertilizer during active growth, switching to a lower nitrogen, higher phosphorus formula once flowering begins to encourage fruit production. Maintain soil temperature above 60°F for optimal growth, and provide support stakes if plants become heavy with fruit.Pruning
Capsicum annuum 'Jalapeño' benefits from light pruning to improve air circulation and fruit production. Pinch off early flowers until plants are 6-8 inches tall to encourage stronger root and stem development. Remove suckers that grow in the crotch between main stems and branches. Late in the season, prune growing tips to redirect energy into ripening existing fruits rather than producing new growth.Pruning Schedule

⚠️ Toxicity Warning
Capsicum annuum 'Jalapeño' fruits contain capsaicin, which causes burning sensations in mouth and skin. While not toxic, the peppers can cause significant discomfort if consumed in large quantities or if seeds and oils contact sensitive areas like eyes. Handle with gloves and wash hands thoroughly after harvesting. Generally safe for pets in small amounts, but may cause digestive upset.Planting Guide
