Need help identifying flower
Need help identifying a flower growing next to my house. I think it is a bulb plant. The foliage looks like wide blades of dark green grass. The flowers are bluish/purple and they close at night.

This is spiderwort, also known as tradescantia. It is a perennial and easily spreads by reseeding. It blooms late spring/early summer. Mine generally go dormant in the hot humid days of summer. I may just have them planted in too dry a location. Anyway, I cut them back to the ground after blooming and get a second growth, although less lush, later on after summer temps cool off a bit.
