Tradescantia subasperaAlso known as:
This species of spiderwort gets its common name because the placement of its stiff, sword-like leaves around its erect stem, gives the plant a "zig-zag" appearance. Tradescantia subaspera may grow over 2' tall, topped with deep violet-blue, three petaled flowers forming terminal clusters.
Tradescantia subaspera is a very adaptable species, tolerant of varied soil and light conditions. It will form dense clumps that should be divided if blooms start to decline. Though its flowers last only one day, it will bloom profusely for 2 months or more, anytime from May to September, depending on geographic location. Zones 5-8
Divide clumps in early spring or late fall. Will self seed under ideal conditions.
Perfect for shade gardens, zig-zag spiderwort can also be used in perennial borders. The foliage will tend to decline when done flowering, but it can be cut back hard, which will encourage a second late summer to early fall bloom. Spiderworts got their name because the viscous secretions they exude when cut, will harden into a thread-like or silk-like form.
