Welcome to the forum, Jason. A typical cigarette formulation consist of a blend of a Virginia variety (sometimes called flue-cured), a burley and a Turkish:
- Virginia: 40%
- Burley: 40%
- Samsun: 10%
That's a reasonable starting place. Since there are scores of Virginia varieties, scores of burley varieties, and scores of Turkish varieties, what you will end up with is bound to be unique.
It's pretty late in the season to start from seed, since it wouldn't go into the ground until nearly July. You might consider ordering ready transplants from BigBonner (a member). He has a recent thread listing available varieties. These could be planted as soon as they arrive.
