S. dooneri flowers & seed pods
I'm pretty sure here in Los Angeles (32deg N) is about as far north as one can successfully grow sans outdoors all year. High temps have been near 70 for the past couple of weeks. But it's been dry, so I've showered all my sans and pray that minimum temps stay above 40.
My parva and dooneri sit in water year around and they seem to love it. Here's a dooneri that has two inflorescence and two seed stalks. If you look closely, you may be able to seed the ripe orange fruit.
