Positive	stevemoeron	On Jul 1, 2003, stevemoeron wrote: We have a plant growing almost exactly like this one but the center is not yellow but a bulbus purple. The other difference is that we are in SW PA and the ground is not marshy. It has been coming up for several years and we have been pulling it for a weed. This year we decided to let it go and it is almost 4ft now.
Neutral	rosemarysims	On Apr 17, 2002, rosemarysims from Opelousas, LA (Zone 8b) wrote: There is also a pure white form of this plant called 'Immaculate' which was introduced by Johnny Mayronne of Natives Nursery, Covington LA. It is sometimes available in the trade.
Neutral	Floridian	On Apr 16, 2002, Floridian from Lutz, FL (Zone 9b) wrote: Native to fresh and brackish marsh areas from New York to Florida and west to Louisiana, this shrubby perennial can top 6 feet and flower much of the summer. Named for the Bohemian botanist V.F. Kosteletzky, this upright perennial mallow is similar to lavatera. It has fuzzy, light green, hibiscus-like leaves and blooms from midsummer through fall and longer in warmer climes. Salt Marsh mallow will grow equally as well in brackish swampy conditions, shallow standing water or in normal garden soil.
