Tradescantia Species, Ernest's Spiderwort

I have not grown this plant which is native to Alabama, Arkansas, Missouri, Mississippi, Oklahoma and Texas. Ernest's Spiderwort (Trades...Read Morecantia ernestiana) can have deep blue, purple or rose-red blooms. It rarely roots from the nodes. Tradescantia ernestiana is easily confused with, T. virginiana. The two species can be distinguished from each other only by the width of the leaf blades and sheath of the distal leaves. T. ernestiana leaf blades are 1 to 4 cm wide with the distal leaf blades wider than sheaths when the sheaths are opened, then flattened. T. virginiana leaf blades are 0.4--2.5 cm wide with the distal leaf blades equal to or narrower than sheaths when the sheaths are opened, then flattened.
