R.Br. ex Ait.f. |}} Baptisia tinctoria (common names include yellow false indigo, wild indigo,[1] wild-indigo[1] and horseflyweed[2]) is a herbaceous perennial plant in the family Fabaceae. It is native to eastern North America. DistributionBaptisia tinctoria is found throughout the eastern United States, west to Minnesota, and south to Florida.[3] As it is rare in some parts of its range, it is protected by some state authorities: in Kentucky it is threatened; in Maine it is considered endangered.[4] It prefers dry meadow and open woodland environments.[5]DescriptionThe multiple bushy stems of Baptisia tinctoria reach 2 to 3 feet tall. The leaves are silver-green; each is divided into three leaflets about ½ inch long. The flowers are yellow and grow in spikes 1½ to 3 inches long.[6] The leaves are eaten by some lepidopteran caterpillars, for example the Io moth (Automeris io). On Martha's Vineyard, the species is a tumbleweed: it grows in a globular form, breaks off at the root in the autumn, and tumbles about.[7] References1. ^{{cite web|title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |archive-url=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archive-date=2015-01-25 |accessdate=2014-10-17 |deadurl=yes |df= }} {{Taxonbar|from=Q783093}}{{Faboideae-stub}}2. ^{{PLANTS|id=BATI|taxon=Baptisia tinctoria|accessdate=9 January 2016}} 3. ^Canby, William.
