Flowers - Calyces 5-lobed, the lobes triangular, the tube to 1 mm long, glabrous. Corollas densely hairy internally, sparsely to moderately hairy toward the tip externally, the tube 7-8 mm long, about 1.5 mm wide at base, the throat 2.5-3.5 mm wide, the lobes 5-8 mm long, 1.2-2.0 mm wide, light blue.

Fruits - Slender follicles to 12 cm long, terete, many seeded, glabrous, erect at maturity, positioned among the leaves, not constricted between the seeds. Seeds 8-10 mm long, the surface usually with low, corky ridges and tubercles.

Amsonia tabernaemontana fruits Fruits.

Flowering - April - May.

Habitat - Open woods, thickets, slopes, ravines, roadsides, railroads.

Origin - Native to U.S.

Other info. - This striking species can be found in scattered locations in the southern half of Missouri and also in a handful of counties around the St. Louis area. It ranges throughout most of the southeastern U.S. The plant is easy to identify becasue of its many blue flowers and broad, pale leaves. This species also bleeds a milky sap when injured. It is very similar to Amsonia illustris , but unlike that species has erect fruits and leaves which are not glossy.

The species has been subdivided into varieties, two of which are currently recognized in Missouri. Variety salicifolia has relatively narrow leaves, to 3 cm wide, and is the most common variety in the state. Variety tabernaemontana has wider (ovate) leaves. The natural ranges of these forms in Missouri have been obscured by escapes from ornamental cultivation and by habitat restoration plantings.

Photographs taken off County Road 40 in the Lowndes Wildlife Management Area, Lowndes County, AL., 4-9-05 (DETenaglia); also at Duck Creek Conservation Area, Bollinger County, MO, 5-18-2014 (SRTurner).
