Admission to the Brooklyn Botanic Garden is free Tuesday through Friday (the grounds are closed closed Mondays, though offices are open) all Winter, from November 20 through February 29. Both the Native Flora Garden and Cranford Rose Garden are closed all Winter, but there's still stuff happening to see.
Come January, the Witchhazels put on their show.
Check out the Bonsai Museum any time.
And this is the best time of year to enjoy the Japanese Garden in contemplative solitude.
