Tradescantia edwardsiana, commonly known as Plateau Spiderwort, is a perennial herb that is evergreen in mild climates. It is native to the Edwards Plateau in Texas, where it thrives in a variety of habitats including grasslands, open woodlands, and along stream banks. This species is adapted to the loamy and sandy soils of these areas, often found in both dry and moist environments. It typically grows to a height of 1-2 feet (0.3-0.6 meters) and a width of 0.5 feet (0.2 meters). The Plateau Spiderwort has grass-like foliage and produces a profusion of tri-petaled flowers that are pink, blue, and purple, blooming mainly in the winter and spring. The flowers are quite showy and attract pollinators such as bees and butterflies.

The Plateau Spiderwort is valued for its drought tolerance and its ability to provide vibrant color in the garden during cooler months. It is often used in border plantings, rock gardens, and as ground cover. For optimal growth, it prefers part shade, although it can tolerate full sun in cooler climates. It requires medium amounts of water and well-drained soil. While generally low-maintenance, it can be susceptible to spider mites and aphids in dry conditions. Gardeners should also be aware that it can spread readily by seed and may require control measures to prevent it from becoming invasive in some areas.CC BY-SA 4.0
