Ever look up at the oxygen-givers around us with wonder? Satisfy your green thumb’s curiosity with a curated tour of trees during the last installment of the Toledo Zoo’s Watch It Grow series on Wednesday, Sept. 19. Like docents in a museum of nature, Zoo horticulturists guide visitors on an hour-long exploration of everything from black gum trees to hydrangea shrubs. The walking tour is free with regular Zoo admission, and registration is not required; participants simply meet in front of the Zoo’s Conservatory, near the aquarium, at 10:30 am. Regular admission $14 adults, $11 children.
