Ready to turn your garden’s winter brown to spring green? The Spring Fling Plant Sale can help.

And if you’re wondering where the turtles go each winter, come back to LSU’s Hilltop Arboretum on Sunday to find out.

From 9 a.m. to 2 p.m. on Saturday at the arboretum, 11855 Highland Road, a large variety of trees, shrubs, plants and lots of gardening extras will be for sale.

There will be horticultural healthcare, to cover pre-existing gardening conditions, and the Podge Posse’s “plant literati” will screen your gardening needs and carefully outline the “perks and quirks” for anything they might prescribe.

The mini “Yarden” sale will offer gently abused, shabby chic gardening items. For more information, visit https://sites01.lsu.edu/wp/hilltop/.

At 3 p.m. on Sunday, a free program on turtles is on tap.

Donald C. Jackson, author of “Life in a Shell, A Physiologist’s View of a Turtle,” will tell us where turtles spend the winter and talk about these remarkable reptiles, which have been around for 220 million years.

Jackson is professor emeritus of Medical Science at Brown University in Providence, Rhode Island, and also has a home in New Orleans.

Copies of his book will be available for purchase and autographing.
