Tradescantia virginiana is a herbatious perennial with a grass-like tufted habit. It has alternate, simple leaves with parallel venation and a centre groove held on tubular stems. The flowers are violet to purple, contrasted by yellow stamens, composed of three petals. Each flower will only open for a single day and will usually close before noon but overall the plant will stay in inflorescence for many months.
T. virginiana is native to eastern North America and commonly known as Spiderwort. It is also botanically known as Ephemerum congestum, Tradescantia brevicaulis, Tradescantia congesta, Tradescantia rupestris and Tradescantia speciosa. It has mainly been grown as a garden flower.
Tradescantia is named after John Tradescant (1608-1662) who served as gardener to Charles 1 of England, with virginiana being a reference to its native range.
