Like most flowering bulbs in Houston this is a member of the Amaryllidaceae family. It only flowers after heavy rainfalls. I had forgotten all about it, and there it was blooming as I left for a morning run. It’s been a rainier year than usual. The total rainfall is typical, the frequency is much higher.
First brought to US in 1854 when Japan and the US opened trade. They are planted in Asia along the edges of rice patties to keep rodents out of the rice.
Prefers full sun, this one is in shade with dappled light only.
Not frost hardy, but this one has been out there for several years, through several cold winters.
Toxic: I think all lilies and Amaryllis are toxic
Prefers lots of water, does best along the edges of rivers
Blooms in Autumn after heavy rain
