A pretty and resilient species with simple Amaryllis style flowers at intervals through the summer, golden yellow inside, red out. They have thrived and seeded about in the tunnel for the last five years, unprotected from the cold and subject to my somewhat sporadic watering. I've not tried them outside yet.
These came to me as seed from a seed exchange labelled Zephyranthes atamasco which they clearly weren't. I've only this year found out what they really are. Aka H.texanus.
