Sun requirement for Madame Jeannette Pepper: Plant in Full Sun
The Madame Jeannette Pepper is a chili pepper cultivar originally from Suriname. The compact plant produces peppers that are a bit larger than habaneros and have curvy, erratic shapes. They can be thin, curved, and slightly wrinkled, or pumpkin-shaped, or look like slightly elongated bell peppers. Peppers ripen from green to yellow. They have a Scoville rating of 125,000 - 325,000 and a fruity taste with hints of mango and pineapple beneath all the spiciness. Like other hot peppers, Madame Jeannettes dislike cool weather. They can be grown indoors in containers. Madame Jeannettes are sometimes confused with Adjuma pepper, which are a bit more round and habanero-shaped. They are used widely in Surinamese and Antillean cuisine.

Madame jeannette pepper facts
What are growing degree days?
A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.
Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.
For Madame Jeannette Pepper, the FAO EcoCrop database gives a lowest growing temperature of 15°C and a shortest growing cycle of 120 days at its best temperature, about 960 growing degree days to a first harvest.
Where you've told us where your garden is, we use this and the weather there to predict when your Madame Jeannette Pepper will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.
