Though I have not tried this plant myself, several sources whom I trust state that this plant is much more cold hardy than listed, even into zone 5b.

Reminds me of watsonia, which strangely, I can't keep alive in my garden. Hesperantha doing quite well so nice substitute.

I have been able to overwinter this plant in the ground in zone 6b. So far, I haven't had much luck getting blooms, but I plan to move it to a wetter area where I think it would perform better.

I like this plant because it adds color to the garden in times of the year when there is not too much other blooms - late summer, fall and sporadically at other times of the year. It does tend to spread so I have to constantly pull out plants so that they don't overrun the place.

Name change from Schizostylis (also spelled Schizostylus)
AKA Kaffir Lily, though name is in disfavor because of the derogatory use in South Africa towards native SA peoples.

Until about 2002 Schizostylus was a separate genus. It was recently combined with Hesperantha. The 1994 edition of the RHS Index of Garden Plants lists Schizostylis as a separate genus of Iridaceae (The Iris Family). It is in fact NOT a lily, Kaffir or otherwise.
