Neutral	Gamblemoore1987	On Nov 12, 2003, Gamblemoore1987 from St. Louis, MO (Zone 6a) wrote: In St. Louis this reseeds but does not last the winter. Hardy, warm season, full sun, annual.
Positive	Terry	On Aug 31, 2002, Terry from Murfreesboro, TN (Zone 7a) wrote: Talk about an easy-to-grow plant. This grows wild in the cow pasture behind our property. The blooms don't have the staying power of the annual petunias but the fact it's a perennial and virtually care-free make up for the lack of profuse blooms.
Neutral	talinum	On Aug 8, 2001, talinum from Kearney, NE (Zone 5a) wrote: Low spreading perennial for dry shade. Misty lavender miniature petunia-shaped blooms throughout summer. Flowers slightly more than 1" acoss. Prefers high heat and humidity. Will reseed occasionally.
