The cormlets can be so prolific that sorting them out is not worthwhile just plant and they can get on with it. The most tender in my experiance is Dichelostemma voubile and D capitata with temperature limits of around 5 F when planted deep in sand, a large pot of B crocea was serverly damaged at these temperatures or slightly lower (0F), (wet and out of doors) and I had only one flower stem last year as a result, -the pot was not fully plunged.
