Paul, I'm certainly no expert on the matter- I can't tell you the proper botanical difference, but can tell you the physical differences. While in Jamaica, one of our assignments was to visit the Boodles' Research Station. They were trying very hard to rescue the scotch bonnet from the general degradation to which all chiles are subject. They were trying to breed a viral resistant 'true' scotch bonnet in order to build up a supply of seed. The physical characteristics they were looking for were as follows- they wanted a pod that had continuous circumfrential canopy about halfway down the pod. It would have four equal and distinct lobes below this canopy. It would have the familiar wrinkled appearance as well. They are usually slightly shorter and squatter than a typical habanaero. While some habaneros match this description, it is not 'typical' of them. The flavor is also somewhat different to me, greatly different to them. They accused the habanero of having no flavor. I did not find them to be nearly as hot as the habs I grow, though they consider the SB to be quite hot. Fresh out of the fields, I did not find them to have the same nearly overpowering flavor that a hab has. These had a much 'lighter' taste that wasn't nearly as fruity as a hab. Scotch bonnets also come in a much wider variety of colors, though the hab is catching up. The plant habit was also different than the habanero. Whereas the leaves on red habs (especially Savina (tm)) are quite large, the SB had a much narrower leaf, similar to but even narrower than an orange hab. The plants seemed to set (or have the potential to set) more fruits than a typical hab. I hope this has been of some help. You might try getting info from Dave Anderson, my fellow Jamaican Junketeer. You can find a little more description in the tech report at my site- provided you don't doze off before you get to that part :-) -Jim Campbell http://www.wildpepper.com
