Crocosmia, don't know exact name. Look up crocosmia and you might find pictures of this one.

MoBot says:
"Only reliably winter hardy to areas where winter temperatures do not dip below 0 F. In USDA Zone 5 (and possibly Zone 6), it is strongly recommended that the corms be dug up in fall and stored over winter in somewhat the same manner as for gladiolus (but do not allow them to dry out completely)."

They'll be the better for digging anyway; they tend to push themselves out of the ground from year to year. Digging and replanting every year insures better bloom.
