Hope the folks in Tennessee don't mind me posting this here, as many of us in MS are close to Memphis. The following was posted on Homesteading site:

No money passes hands here. You bring your extra seeds, plants of all kinds ( water, shade, house ), or anything plant related ( books, containers ) and swap with the others there. We love to meet new plant people. Come one and all!

There will be a potluck lunch and a plant speaker.

The address to the church is

6050 Summer Ave

Memphis, TN 38134

This is Saturday the 24th . Starts at 10:00
