Special Significance of the Species

Western spiderwort is one of several species found exclusively in the fragile sand dune habitat of the southern Canadian prairie provinces. The very recognizable western spiderwort may serve as an indicator species for the well-being of the sand dunes it inhabits. Although the particular horticultural use of western spiderwort is unknown, several other species of spiderwort are grown horticulturally.
