Thank you for sharing this! That flatwoods plum looks so much like Scarlet Beauty. Sure hope my Scarlet Beauty isn't on that short-lived rootstock, it's one of my favorite trees. Great to know it can be grafted onto flatwoods.
Looking forward to future posts, really appreciate how much you've shared over the years about Florida fruits, e.g. deerberry, sparkle/farkleberry, mayhaw, maypop, FL jujube, etc.
@roblack, great idea about a squirrel distraction system and planting more natives!
