Here is a good overview of 14 pepper cultivars grown by a home gardener in South Florida (part 1 and part 2 videos):
I grow mostly 2 types of pepper in South Florida:
- Waialua Pepper. Waialua chili pepper is a Jalapeno shaped, weighing about 26g. Matures in about 75-80 days. Pepper is resistant to Bacterial Wilt and is tolerant to root knot nematodes. Fruits mature to a beautiful red color and is sweeter flavored than Jalepeno. Fruits are about 1.5 to 2 inches in length.
- Kaala Bell Pepper. Kaala is a sweet pepper resistant to Bacterial Wilt and tolerant to root knot nematodes. Fruits are 1/3 the size of normal bell peppers(102 g) and will turn red when mature. Matures in about 75 days.
Both are stable varieties (not hybrids), available for only $1 packet from the University of Hawaii: http://www.ctahr.hawaii.edu/seed/seeds.asp
