TAM 111 Jalapeño Pepper
Capsicum annuum 'TAM 111'
vegetableTAM 111 is a heat-tolerant jalapeño pepper cultivar developed at Texas A&M University, bred specifically for hot climates and drought resistance. It produces medium-sized, dark green jalapeños (2-3 inches long) that mature to red and offer the classic 2,500-8,000 Scoville Heat Units. This variety is particularly valued for its ability to set fruit reliably even in extreme heat conditions.

Seedling
3-4 weeksTiny seedlings with cotyledons (seed leaves) appear 7-14 days after germination. First true leaves develop over 2-3 weeks.
Maintain warmth (75-85°F), high humidity, and bright light. Keep soil consistently moist but not waterlogged. Thin crowded seedlings or pot up at true leaf stage.
Vegetative Growth
4-6 weeks after transplantPlant develops bushy branching structure with increasingly larger leaves. Compact, bushy habit (12-18 inches tall). No flowers yet.
Harden off before transplanting outdoors. Plant after last frost when soil is warm (60°F+). Stake early if needed. Remove lower leaves as plant grows for air circulation.
Flowering
3-4 weeks; flowers appear in flushesSmall white flowers with yellow centers appear at leaf nodes along branches. TAM 111 produces abundant flowers even in high heat.
Maintain consistent watering and mulch to regulate soil temperature. Avoid excess nitrogen, which promotes leaf growth over flowers. Ensure good pollination with gentle shaking or bee activity.
Fruit Development & Maturation
4-6 weeks per fruit cycle; multiple flushes possibleGreen peppers form where flowers were, growing to 2-3 inches. Peppers mature from dark green to bright red over 2-3 weeks per fruit.
Continue consistent watering; slight stress can increase heat levels. Support heavy fruit clusters with stakes or cages. Harvest some green peppers early to encourage more flowering.
Peak Production & Harvest
8-16 weeks or until frostPlant produces continuous waves of fruit throughout growing season if temperatures stay warm (70°F+). Peppers ready to pick at green or red stage.
Keep harvesting to maintain production. Prune any dead branches. Continue regular fertilizing with balanced or slightly phosphorus-rich fertilizer every 2-3 weeks.
Common Pests

Uses
Fresh Cooking & Salsas
CulinaryGreen TAM 111 jalapeños are excellent for making fresh pico de gallo, salsas, and as pizza or burger toppings. The mild to moderate heat (2,500-8,000 SHU) makes them accessible for most palates while adding authentic jalapeño flavor. [source]
Pickling & Preservation
CulinaryTheir firm flesh holds up exceptionally well to pickling and canning, making them ideal for preserving. Pickled jalapeños can be stored for months and used in nachos, tacos, and charcuterie boards. [source]
Roasting & Smoking
CulinaryRed-ripe TAM 111 peppers are excellent for roasting whole, smoking (as in chipotle-style preparation), or drying. Roasted peppers develop deeper, sweeter flavors perfect for sauces and soups. [source]
Digestive & Metabolic Health
MedicinalJalapeños contain capsaicin, which is studied for its anti-inflammatory properties and potential to support digestion and metabolism. Consuming jalapeños may increase circulation and have antimicrobial benefits. [source]
Heat-Tolerant Ornamental Garden
HouseholdTAM 111's compact, bushy habit and prolific fruiting make it attractive in vegetable gardens and even ornamental containers. Its ability to thrive in extreme Texas heat makes it ideal for low-water landscaping in hot climates. [source]

Harvest Tips
Pick peppers when dark green and firm (about 3 inches long) for use in salsas, pickles, or fresh cooking. For red peppers with higher sweetness and vitamin C, allow 2-3 more weeks of ripening on the plant. Use pruning shears or a knife to cut peppers rather than pulling, which can damage branches. Harvest regularly to encourage continuous production. TAM 111 tolerates picking at any stage from immature green to fully red.
Fun Facts
- 🌱 TAM 111 was specifically bred at Texas A&M University (TAM = Texas A&M) to handle extreme heat and drought conditions, making it one of the most heat-tolerant jalapeño varieties available and ideal for climate change-adapted gardening.
- 🌱 Unlike many pepper varieties that stop flowering and setting fruit when temperatures exceed 90°F, TAM 111 continues reliable fruit production even in 100°F+ heat, which is why it dominates commercial jalapeño production in Texas.
- 🌱 The name 'jalapeño' comes from Xalapa, a city in Veracruz, Mexico, and jalapeños are technically fruits (botanically berries), not vegetables—and they're actually the same species as bell peppers, just a different cultivar with heat genes activated.
