Plants are important to our community, but many organizations overlook their importance around the home and office. National Indoor Plant Week returns the week of September 17, and Engledow Group is making it easier than ever for Hoosiers to include greenery in their homes and workspaces. On Tuesday, September 18, Engledow will give away 3,000 arrowhead vine plants on a first-come, first-served basis—all guests have to do is stop by Monument Circle from 11 a.m. until 1 p.m., or until plants are gone.
