You can count on finding a riot of color among the blooms and foliage at the UT Gardens in Knoxville. This year, though, you’ll see more silver among the beds of annuals, perennials, herbs, and trees that abound throughout the 5 acres along Neyland Drive. The UT Gardens is celebrating its 25th, or silver, anniversary. In honor of the occasion, curator James Newburn (Knoxville ’95, ’08), gardens interim director Dr. Sue Hamilton (Knoxville ’80, ’95), and students are growing such silver plants as artemisia, dusty miller, and silver sage on the agriculture campus. They are also joining with the Friends of the Gardens to dedicate a new Friendship Plaza, a sweeping entryway designed to welcome the 50,000-plus visitors the gardens host each year.
