The classic Habanero. This strain is called the "Chichen Itza Habanero," having been bred to produce a slightly higher yield and earlier in the season. This plant grows up very quickly and will give you hundreds of habaneros per plant.
There are too many ways to enjoy a habanero. This was the hottest natural pepper in the world for a very long time, until 1994 when a hotter strain of habanero, the Red Savina, took the record. With it's distinct apricot-like flavor, this is a great pepper for hot sauces and pepper jams.
