> a tough, reliable old thing
May be an apt description. It's been around here for a number of years, the last 2-3 in an abandoned bed where it has coped successfully with a number of noxious weeds. Except for a single attempt once (not successful, BTW), the bloom has always been spring bloom. Too often bloom is faded and drab, but some years the colors have been more intense and it's been an appealing clump. But it's been tough. Got seeds once using AB pollen. One plant resulted and it didn't survive to bloom.
