Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
Mine is the Talinum paniculatum; if I don't do a good job of gathering the seeds they will re-seed all over the garden.
Not sure if that's true for your T, triangulare.
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
