This is interesting, Jim. I don't know which side of South Africa they 
come from, but here in So. California I see them almost naturalized 
(even a few up the canyon in the national forest area) and they are 
definitely a natural winter-grower/summer-dormant plant in this climate. 
(Which could explain the too-early emergence for you.)
