TRADESCANTIA occidentalis (Prairie Spiderwort) is a herbaceous perennial plant that is native to the central and western regions of North America. Like other members of the Tradescantia genus, Prairie Spiderwort is part of the Commelinaceae family and is appreciated for its attractive flowers and adaptability to different growing conditions.
Prairie Spiderwort typically grows to a height of 1 to 2 feet (30 to 60 centimeters) and forms clumps of grass-like leaves. The leaves are long, narrow, and sometimes slightly hairy. The flowers are held on delicate stems and have three petals. The blooms are usually a beautiful shade of blue or violet, occasionally pink or white.
This plant is well-adapted to a variety of soil types, including clay, loam, and sandy soils. It prefers well-draining soil and can tolerate both dry and moist conditions. Prairie Spiderwort thrives in full sun to partial shade, making it suitable for a range of garden settings.
The flowering period for Prairie Spiderwort generally occurs in late spring to early summer. Each flower opens in the morning and typically lasts for only one day, but new blooms continue to appear throughout the flowering season.
Prairie Spiderwort is pollinated by insects like bees and butterflies, and its nectar-rich flowers are attractive to these pollinators. It also provides food and habitat for other wildlife, making it beneficial for biodiversity.
This plant is well-suited for native plant gardens, prairies, meadows, and naturalistic landscapes. It can also be used as an accent plant or border plant in mixed gardens. Prairie Spiderwort's lovely flowers and low maintenance make it a favorite among gardeners interested in native and wildlife-friendly planting.
