I had never heard of this so it piqued my interest...after a bit of time on Google, I can recommend that you try a search using the spelling "texsel greens" and you will find some sources in the U.S. It is also called Brassica carinata. Good luck!

"I like to believe that each person can decide for themselves whether or not a plant in a given situation is threatened to a point that it would be more beneficial to move it than to leave it where it stands, whether it is in a park or on a roadside or any public property. " A roadside is not punblic property. I think it would be of interest that in many cases when only a single individual of a plant species exists that plant is left as undisturbed as possible and is propegated instead of moved, because even then moving the plant is not more beneficial (indeed, probably worse) to leavin it. Those singular individual plants in question are not, however ignored. By looking at that example, NO plant is 'threatened to a point that it would be more beneficial to move it than to leave it where it stands' unless imminent destruction in the near future is likely due to human activites. Therefore in almost any surcumstances leaving the plants is definatly the better option, but some site care such as checking and removing all weeds in the vicinity of the plants is vastly better than moving them. Also, if you cant do that site maitence (for example, not on your land)your probably not supposed to be moving plants from there anyway. Unless you have premission of course, preferably permission to maintain the site. A roadside planting is most likely secure, and with the wildflowers and garlic mustard, perirodic weeding in the imidiate vicinity of the plant population may be all that is required for the long-term presistance of that population. It is interesting to note that in certain curcumstances (for example, native wild plants transplanted to a neatly kept garden) the population of transplanted plants are unlikely to survive in the long-term because they may not reproduce. While the individual transplanted plants may survive, the establishment and long-term presistance of a self-supporting population in in doubt, altough it can and does happen, it might just as easily not because of many subtle variables affecting the growing site means establishment of said transplanted plants might be in unlikely. Without long-term presistance of a self-supporting population, it, in my mind atleast, not a resce in the sence that these plants have been removed from a population that probably needs all the individuals it it can get, and presistance in the wild is far more important, ecologicly speaking, than presistance in cultivation. Note: the terms Establishment and self-supporting population does not just mean that the species sometimes reseeds itself, altough that is a important factor in the process. In the case of this garlic mustard weeding within the viicinity of the plants on a regular basis would probably ensure theri survival in the short term, altough their long-term survival may be in doubt because, lets face it, you wont be there forever to weed. WHat might work is if you suceed in reducing garlic mustards population density in the area.

Keep up the good fight against Garlic Mustard. It spreads so quickly and overwhelms everything in its path. Did you know that the West Virginia White Buterfly mistakenly lays its eggs on GM mistaking it for the host plant. The eggs never develop into butterflies. GM germinates in Sept/Oct. Learn to recognize the seedlings and they can be zapped with herbicide at that time. If you are confident of the location you can even apply corn-based pre-emergent herbicide before they germinate which will have minimal effect of other plants.

I bought a plant for my raised beds at Marshall Grain and it turns out the plant was mislabeled. I have a Giant Red Mustard Plant if anyone would like it. I'm on the west side of Southlake.
