Species from the western US, apparently similar in most respects to the S. angustifolium we've grown before. One of our second-year plants bloomed (the one out in the rock garden; the other one, in one of our hypertufa troughs, is much less happy for some reason.

Sisyrinchium idahoense
Somewhat evergreen: many leaves die back, but there's a core tuft of green in mid-March after snow recedes

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.

Seed for this plant is included on my seed trade list
