Native to meadows, woodland borders and streamsides of eastern and central US, this herbaceous perennial is a member of the bean family, Fabaceae, that also includes lupine, mimosa, and black locust.  The plant quickly grows 3-4′ tall and develops into a substantial, vase shaped bush with gray stems carrying trifoliate, gray-green with leaflets up to 2′ long.  In spring,  racemes up to 16” long appear bearing soft blue flowers similar in shape to those of sweet pea. Black pods 2”-2 1/2” long follow and remain until fall when the stems and leaves die down. They add to the over all attractiveness of the plant and are also desirable additions to flower arrangements. Although Baptisia is a large plant, it is not heavy or coarse and therefore looks well at the front or back of the border where it can add variety in size as well as in texture and color. Baptisia is very long lived and resents being moved so should be placed where it can remain and be enjoyed.Thegenusname,Baptisia,is from the Greek word βάπτω (bapto), meaning to dip or dye, and refers to the use of plants in the genus as an indigo dye. The specific epithet, australis, comes from the Latin word auster, meaning south, and refers to the geographic range of the plant.
