Species Native to Missouri
Common Name: spiderwort
Type: Herbaceous perennial
Zone: 4 to 9
Height: 1.00 to 1.50 feet
Spread: 1.50 to 2.00 feet
Bloom Time: May to July
Bloom Description: Rose to purple
Sun: Full sun
Water: Dry to medium
Suggested Use: Ground Cover, Naturalize
Tolerate: Drought, Dry Soil, Shallow-Rocky Soil
Grow in average, dry to medium moisture, well-drained soil in full sun. 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. May self-seed and spread in the garden in ideal growing conditions.
Small spiderwort is a compact, clump-forming herbaceous perennial which typically grows to 1.5' tall. Rose to purple, three-petaled flowers (.75-1.5" diameter) accented by contrasting 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 late May into early July. Arching, iris-like, dark green leaves up to 1' long and 3/4" wide are folded lengthwise forming a groove. A Missouri native plant that is found in sunny locations on prairies, meadows, fields, roadsides and railroad right-of-ways. When the stems of spiderworts are cut, a viscous stem secretion is released which becomes threadlike and silky upon hardening (like a spider's web), hence the common name.
No serious insect or disease problems. Young shoots are susceptible to snail damage. Foliage sprawls in an unattractive manner by mid-summer.
An interesting and long-blooming perennial for native plant gardens, wild gardens or naturalized areas. Also effective in borders and rock gardens, but mid-summer foliage decline is a potential disincentive for a prominent placement therein.
