The tobacco flower tends to be self- pollinated, but self-pollination is not sufficiently assured to make protection unnecessary when pure seeds are de- sired.Normally, the tobacco plant is pollinated by hawkmoths that visits its flowers every night. But when these hawkmoths leave eggs behind that develop into leaf-chomping caterpillars, the plant’s self-defense snaps into place and switches to flowering in the day. That attracts a different pollinator, the hummingbird.Tobacco is cultivated as an annual but is actually a perennial and is propagated by seed. The seeds are sown in beds. One ounce of seed in 100 square yards of soil can produce up to four acres of flue-cured tobacco, or up to three acres of burley tobacco.
