What does "Habana" mean?

[T.G]

Depends on the context.

It can refer to the use of one of the various Habana___ hybrid strains of tobacco, such as the Habana2000, sometimes called H2000. (which I believe is trademarked by Altadis, so when anyone else uses that seed, they have to call it something different) . It is more and more commonly being used to generically refer to any type of Cuban seed tobacco.

Or, sometimes, it's just tossed into the name of the cigar to make it sound good for marketing purposes.

Some manufacturers put it on the band, maybe for history, maybe for marketing, maybe to pay tribute, I dunno, you'd have to ask them, I'm sure reasons vary.
