Tradescantia bracteata aka Long Bract Spiderwort
Taxonomy ID: 10748
Tradescantia bracteata is a small perennial in the Commelinaceae family. Common names include prairie spiderwort and small spiderwort. Its native range covers the northern and east-central United States. In Missouri, it grows in open, sunny places. These include prairies, meadows, fields, roadsides, and railway land. It forms compact clumps rather than woody stems.
Garden plants reach about 1.5 feet (0.46 metres) tall. Their spread reaches about 2 feet (0.61 metres). The dark green leaves arch out from the clump. They can reach 1 foot (0.30 metres) long. Each leaf folds along its length, making a groove. The narrow, curved leaves give the plant an iris-like form. This neat shape can loosen as summer moves on.
Flowers range from rose pink to purple, with yellow stamens. Each flower has three petals and lasts just one day. The blooms measure about 0.06–0.13 feet (0.02–0.04 metres) across. They open a few at a time in terminal umbels. Each cluster holds many buds, which extend the flowering season. Bloom runs from late May into early July. The bright flowers stand out against the dark leaves.
Grow this spiderwort in full sun and well-drained soil. It accepts average soil and also tolerates poor ground. Moist, acidic soil suits it best, despite its drought tolerance. It can also cope with dry and shallow, rocky soil. Its usual moisture range runs from dry to moderately moist. It is hardy in USDA zones 4–9. Divide the clumps when growth becomes crowded. Plants may spread by seed where conditions suit them.
Prairie spiderwort fits native plant gardens and less formal planting. It also works as ground cover in naturalized areas. Borders and rock gardens can show off its spring flowers. Yet its leaves may decline and sprawl by midsummer. This limits its value in a highly visible spot. Cutting faded growth nearly to ground level encourages fresh leaves. It may also bring another flush of flowers in fall. No major insect or disease problems are reported. Snails can damage the tender young shoots.
