My spiderwort is taking over my garden...is it an invasive plant? How can I confine it?

Native or garden spiderworts have three blue or purple petals to tropical spiderworts' two and bloom for several weeks atop clumps of smooth, lance-shaped leaves 18 to 24 inches tall. Snap off flowers as they fade to prevent self-seeding, though these plants are not considered invasive.
