Growing Cayenne Purple Peppers in the Vegetable Garden
It is recommended to start seeds indoors about 8-10 weeks before your last expected frost date. Plant the seeds about 0.25 inches deep in seed starting mix such as coco coir. Seeds germinate best between 70-85 F. Keep them moist until true leaves develop. Once seedlings have developed several true leaves and outdoor temperatures consistently stay above 55 F, it's time to harden them off. Gradually expose the plants to outdoor conditions over 7-10 days, starting with a few hours of morning sun and gradually increasing their time outside.
After hardening off, transplant seedlings into the garden or containers when nighttime temperatures remain above 60 F. Space plants 12–24 inches apart in well-draining soil enriched with organic matter. Apply a balanced fertilizer (such as 10-10-10) at planting time. Ensure they receive full sun for optimal growth. Keep the soil consistently moist but not waterlogged. Water deeply once or twice a week, depending on rainfall and temperature. Mulching can help retain soil moisture and suppress weeds. Once the plants begin to flower, switch to a fertilizer higher in potassium and phosphorus to encourage fruit development. Follow the manufacturer's instructions for application rates.
Harvesting Cayenne Purple Hot Peppers
The peppers start green and turn deep purple, measuring around 3 inches long. You can harvest them at the green stage for a slightly milder flavor or wait until they turn purple for maximum heat. Use sharp scissors or pruning shears to cut the peppers from the plant. Wear gloves when handling the fruit and avoid touching your face. These hot peppers can cause irritation to sensitive areas.
About Cayenne Purple Hot Pepper Garden Seeds
Purple Cayenne peppers are known for their ornamental appeal as much as their culinary appeal. The dark fruits are glossy and attractive hanging on the plant.
Purple Cayenne Peppers are versatile in the kitchen. They can be used fresh in salsas and salads, dried and ground into powder, or pickled for long-term storage. Their vibrant color also makes them an attractive garnish.​
These peppers are well-suited for container gardening. Choose a pot at least 12 inches in diameter with good drainage. Container-grown plants may require more frequent watering and fertilization

Purple |
Cayenne Purple Hot Pepper Flavor: |
Spicy with fruity and earthy undertones |
Growing Info
Hardiness Zone: |
4, 5, 6, 7, 8, 9, 10, 11 Technically a tender perennial, but commonly grown as an annual. Perennial in zones 10 and 11. |
Days to Maturity: |
75-85 (from transplant) |
Days to Germination: |
7-10 |
Seeding Depth: |
0.25 inch |
Plant Spacing: |
12-24 inches |
Row Spacing: |
24-36 inches |
Plant Height: |
18-24 inches |
Growth Habit: |
Upright |
Soil Preference: |
Well-draining, loose (sandy loam), slightly acidic (6.5 pH), and moisture retaining. Too much nitrogen in the soil may lead to more foliage production and less fruiting, similar to tomatoes. Peppers also need sufficient amounts of phosphorus and calcium. We recommend using a balanced fertilizer for the best results. |
Temperature Preference: |
Warmer (70-85 F). During high heat, foliar and flower development slow or pause until temperatures return to the preferred range. |
Light Preference: |
Full Sun |
Other
Direct Sow: |
No |
Start Indoors: |
Yes. Start Indoors 6-8 weeks before your last spring frost date. Harden off and transplant when seedlings are 6-8 inches tall. Bury the stem slightly deeper than the root ball. Avoid planting hot and sweet peppers right next to each other, as they can cross-pollinate, potentially affecting the flavors of your harvested peppers. |
Pepper Pollination: |
Peppers have perfect flowers (male and female parts) and will self-pollinate. However, wind and pollinator activity may increase success rates of fertilization and fruit production. |
Plant Width: |
24-36 inches |
Deer Resistant: |
Yes |
Scoville Heat Units: |
30,000-50,000 |
Heat Level: |
Hot - 30,000 to 100,000 on the Scoville Scale. Example Cayenne & Tabasco. |

Mid - Ready for harvest around 76 to 90 days from transplant. |
Germination Temperature: |
80-90 F |
Pests and Diseases: |
Peppers are commonly susceptible to cutworms, aphids, flea beetles, bacterial spot, Phytophthora, sunscald, and blossom end rot. To avoid or reduce problems with pests and diseases, stick to a regular watering schedule (drip irrigation is preferred), plant into well-draining soils, and utilize practices such as crop rotation. When taking pest control measures, consider utilizing integrated pest management principles by using mechanical removal, biological control, and other cultural practices before turning to chemical agents. |
