Dear Alberto,

Thanks for the help. So if this is Oxalis tetraphylla 'Iron Cross' that
bloomed for me last May through November and is blooming again that I
originally got from Uli as Oxalis triangularis whoever ordered if from the
BX 22 please change the name with my apologies. I hope you didn't already
have it. It's a great plant regardless of its name.
