Tradescantia Vs Commelina
I am trying to find a reliable and quick way to identify and distinguish
Tradescantia fluminensis (Wandering Jew) and Commelina cyanea (Scurvy weed) when they are not flowering. TF has white flowers and CC has blue but what if there are no flowers? I care because TF is a declared noxious weed here and CC is not and I don't want to put in unecessary effort removing the wrong one. It seems that CC has leaves that are slightly wider spaced, narrower and paler than TF but unless I have the two side-by-side I have trouble distinguishing them by these quantitative characteristics. Are there any clear qualitative indicators except the flowers? David |

The only reliable way to distinguish them is by the flowers.
