For most temperate areas of the US, it's pretty late to start seed. (It requires 4 to 8 weeks between starting the seed and transplanting out to the garden.) If your zone is sub-tropical, then you could still start seed for this year. Another possibility is to order transplants from BigBonner (a member of this forum), and have them in the ground by next week.
Be sure to look over the Tobacco Growing FAQ, for many of the basics. You can use any variety to make snuff or dip. Traditionally, the dark-air-cured varieties [e.g. Little Yellow, One-sucker] and dark-fire-cured [e.g. Greenleaf, Madole] were used for snuff and chew.
How many plants are you considering?
