There are more than 10,000 flowers along the High Line, and to help you identify them, the NYC park is offering a FREE flower guide. There’s a free guide each month with the flowers blooming that month. In April, the list includes Sicilian honey garlic, black chokeberry, and tulips, of course. The list is also by section, so you can zoom in to the horticulture on the High Line’s Northern Spur or Washington Grasslands. Click here to download. And be sure to print and take the guide with you on your next visit.
