Germination speed, temperature needs, and reliability vary considerably across Capsicum species. This chart gives growers a quick reference for what to expect from each species under typical conditions.
| Species | Code | Germination Time | Optimal Temp | Notes |
| Capsicum annuum | A | 7–14 days | 75–85°F (24–29°C) | Standard; fast and reliable with warmth |
| Capsicum chinense | C | 10–21 days | 80–90°F (27–32°C) | Slow to germinate; needs high consistent heat |
| Capsicum baccatum | B | 10–18 days | 75–85°F (24–29°C) | Moderate speed; prefers moist warmth |
| Capsicum pubescens | P | 14–30 days | 70–80°F (21–27°C) | Slow; cooler temps preferred, pre-soak seeds |
| Capsicum frutescens | F | 10–20 days | 80–90°F (27–32°C) | Similar to chinense; needs warmth and moisture |
| Capsicum praetermissum | D | 14–25 days | 75–85°F (24–29°C) | Wild type; erratic but responsive to bottom heat |
| Wild types (e.g. C. chacoense) | W | 14–30+ days | 75–85°F (24–29°C) | Often need pre-treatment; slow and variable |
