PINK TEXAS STAR
Pink Texas Star. Prairie Sabbatia (Sabbatia campestris) is also known as meadow pink, rose pink, pink prairie gentian, marsh pink, and sea star. It ranges from Missouri and Kansas to Texas and is found on moist prairies throughout Central Texas from April to June. It is particularly abundant on southern coastal prairies where it makes a showy landscape display with phlox, coreopsis, and other plants in March and April. The sabbatias are named in honor of two Italian botanists, L. and C. Sabbati.
The plants are low, 3-12 inches high, and have wing-angled stems and short smooth leaves about ½-1¼ inches long. The flowers are about 1½ inches broad, much larger than those of the mountain pink, and more cup-shaped. They are usually deep pink in color, but purplish-pink and white forms may occasionally be noted. Around the throat are yellow, star-shaped markings over the white base of the petals. The long, linear calyx lobes are quite conspicuous when the flower is in bud or after the corolla has wilted.
DOGBANE FAMILY (Apocynaceae)
BLUE TEXAS STAR
Plants with milky juice; sepals usually 5; corolla tubular, 5-lobed; stamens usually 5, inserted on corolla tube and alternate with the lobes; ovary superior; fruit mostly of 2 spreading follicles.
Blue Texas Star. Texas Dogbane. Blue-Star (Amsonia texana) belongs to a group named in honor of Charles Amson, a colonial physician. The stems are usually unbranched, 8-12 inches high, and are covered with narrow linear leaves. Like that of other amsonias, the tubular throat is lined with white hairs. The name of twin-pods might be given to the amsonias. The numerous seeds are borne in two narrow, erect pods which are united at the base and split along the inner sides. The pods are 3-4 inches long. The plant is perennial, growing in low clumps on limestone hillsides of Texas. The plants in North Texas form a conspicuous bluish-green line on low hills, when the flowers bloom in late March and April.
The oleander, periwinkle, and vinca are well-known members of the dogbane family. They all have a milky sap which is quite poisonous in the oleander, Indian hemp, and others. “Bane” is the common word in Northern Europe for “murderer” and is applied to poisonous plants.
