The cob-like buds of tropical gingers are exciting in their own right.  And just soon enough (Hurry!  Frost will come in a week or two!) each cob will sprout several dozen fragrant orchid-like flowers.  Then it's time to bring the gingers into shelter for the Winter; they're only hardy in-ground from, say, North Carolina southward.  But then again, to have them thrive in New England is, by far, the bigger thrill.
