Well see your first mistake was you planted them. I have the yellow and them purple leaved and planted neither. The purple leaved one propagates by runners. I think it is going to be very difficult to get rid of it. I may just leave it. It is in a raised bed. Today is a boxing up packages day. That will make my total day when this project is off my list. I am going to leave some of the soil around the bulbs but I have great organic soil. I do not use pesticides. I will also separate them into separate plastic bags.
Yes, last Friday I was helping a neighbor with her landscape. It was freezing cold, to me anyway, and high winds. Now this weekend we are suppose to hit high 90s. OMG.
