Giant Spiderwort (Tradescantia gigantea) grows in clumps of stout stems 2-3 feet high. The numerous flowers on short slender stalks hang out of a cluster of 2-3 upper leaves which have sac-like bases, velvety with soft hairs. The 3-petaled flowers vary in color from purplish-blue to rose or white and close at noon. The 6 stamens are adorned with lovely violet hairs. It is found in Central Texas in April and May.
The spiderwort group was named for Tradescant, gardener to Charles I. It is well represented in Texas, all of the many different species being easy to transplant and making attractive garden plants. The wandering jew, a well-known spiderwort in cultivation, is a native of South America.
Prairie Spiderwort (T. bracteata) is a smaller plant with bluer flowers. Ranging from Minnesota to Texas, it has its blooming season in Texas in April and May.
TEXAS DAYFLOWER WIDOW’S TEARS
Curly-Leaved Dayflower. Widow’s Tears (Commelina crispa) has two large blue petals and a third, minute, white, and inconspicuous. The upper three stamens are 4-lobed and sterile, quite different from the 3 lower pollen-producing stamens, one of which is larger than the others. The petals are very tender and last only one morning. This dayflower may be distinguished from several others in the state by its crisped leaf-margins. It is very common on the South Central Plains from May to September. The name is given in honor of early Dutch botanists by the name of Commelyn.
Texas Dayflower (Commelinantia anomala) has two large petals like the dayflowers, but may be distinguished from them by their lavender color and by having the leaf around the flower-cluster more like the lower leaves in shape. The three upper stamens are bearded with violet hairs like those of spiderworts. It grows in rich moist soil in the limestone hills of the southern part of the state and the adjoining part of Mexico.
