Just to add that I germinated a tray full of D.binata seed during the 
late summer.  The seedlings are still very small (a few mm across).  
The  parent plant has died down, but these seedlings are just sitting 
there.  We have had a couple of very cold snaps (-6c) and the 
compost of the seed tray was frozen solid one morning.
