Species Native to Missouri
Common Name: spiderwort 
Type: Herbaceous perennial
Family: Commelinaceae
Native Range: Southern Missouri, northern Arkansas
Zone: 4 to 9
Height: 0.50 to 0.75 feet
Spread: 0.50 to 0.75 feet

Grow in average, medium moisture, well-drained soil in part shade. Prefers moist, acidic soils. Tolerant of poor soils. Divide clumps when they become overcrowded. Foliage declines after flowering and should then be cut back almost to the ground to encourage new growth and a possible fall bloom. Can self-seed and spread in the garden in ideal growing conditions.

Noteworthy Characteristics

Tradescantia longipes, commonly called wild crocus, is a low-growing, clump-forming, herbaceous perennial endemic to rocky, wooded slopes in the Ozark region of Missouri and Arkansas. Mature clumps will reach 8" tall with a similar spread. Deep blue to purple, three-petaled flowers (.75-1.5" diameter) accented by fringed yellow stamens open up, a few at a time, each for only one day, from terminal clusters (umbels) containing numerous flower buds. Flowers bloom in succession from May to June. The arching, grass-like leaves can reach up to 7" long and 1/2" wide.

Genus name honors John Tradescant (1570-1638) and his son John Tradescant (1608-1662), botanists and successive gardeners to Charles I of England.

The specific epithet longipes means "long-stalked" in reference to the relatively long pedicles (flower stalks) which can reach over 2" long.


No serious insect or disease problems. Young shoots are susceptible to snail damage. Foliage sprawls in an unattractive manner by mid-summer.


An interesting native perennial for rock gardens or native plant gardens. Also appropriate for open woodland or shade gardens, wild gardens or naturalized areas. Also can be grown in borders, but mid-summer foliage decline is a potential disincentive for this placement.
