The delightful blue flowers of Spiderwort are produced over a long period of time during late spring and early summer. Opening first thing in the morning, the blooms are closed tight by early afternoon. Tradescantia ohiensis grows easily from seed and thrives in a wide variety of moisture conditions
Tradescantia ohiensis is a clump-forming herbaceous perennial which grows up to 3' tall with dark bluish-green, arching, grass-like leaves up to 1.5' long and 1.75" wide which are folded lengthwise forming a channel or groove. Clusters of blue (less frequently rose), three-petaled flowers (0.75-1.5" diameter) bloom from late May into early July. Each flower opens up for only one day.
Easily grown in average, dry to medium, well-drained soil in full sun to part shade. Very tolerant of part shade, but bloom may be less profuse. Prefers moist, acidic, sandy soil. Divide clumps when they become overcrowded. Cut back to 6-12" in mid-summer to encourage new growth and a possible fall bloom. An interesting and long-blooming perennial for the border, naturalized area, meadow or open spaces of the woodland garden.
The seeds have a dormancy period. They need a period of chilling which simulates winter conditions to break their dormancy. Seeds germinate with a fall planting, or following a period of moist-cold stratification.
