Learn from noted horticulturists and top industry professionals in our popular JCRA lectures. From new plant introductions, green industry trends, and exotic exploration trips in search of new plants, we cover a variety of timely, cutting edge topics that appeal to both home and professional gardeners.

Along with specially scheduled lectures, our monthly Friends of the Arboretum Lecture series covers the entire spectrum of horticulture. FOA Lectures are free for members and $5.00 for guests.
