Long known as Littonia modesta, this little charmer from southern Africa at first glance hardly resembles the other members of its genus. For comparison, look here to see its more flamboyant relative, the gloriosa lily: http://mcwort.blogspot.com/2016/09/gloriosa-superba.html
Once included in the lily family, they are now in the Colchicaceae.
The flowers of this little orange one did not prove to be very enduring - they lasted only three days. The flowers of the big showy gloriosa lilies last much longer than that.
This is a new plant for me: it came from the bulb exchange of the Pacific Bulb Society; thanks, MSI!
