South American mock vervain, Glandularia pulchella

South American no longer? Starting from Brazil, Uruguay and Argentina, this mock vervain has been moving north. Gardeners helped a lot. With its low, even creeping habit it is a good choice for dry and rock gardens. Now in some areas of the south they are starting to think about invasiveness. But the jury is still out, and in any case if you want to plant some for the season farther north, no worries. South American mock vervain has been reported wild from AL, AR, AZ, CA, FL, GA, KY, LA, MO, MS, NC, NM, SC, TN, TX, and UT. Lowndes Co GA, 1/29/13. Vervain family, Verbenaceae.
