What Hot Pepper said, but want to add that the store was not wrong. Habanero is a HUGE category. For what ever reason, when folk think hab they think about the orange / yellow ones you find in the grocery store for a few bucks a pound. The one you have there is very well sought after, so you got lucky. Seriously, the number of times I purchased Scotch Bonnet seeds only to get the normal grocery store shape is unreal.
Example of the diversity: Was trying to collect black peppers to go with orange for a Halloween thing. Ordered in Large Black Habanero seeds. Got brown, which is kind of normal when they say black, but large doesn't describe the things. They are frigging huge. Huge like wont fit in a flat rate box huge. Not as large as a bell, but damn close to some of the smaller bells. Now on a how big can a habanero grow kick.
