I'm a big fan of this flower & have a nice collection. Last year, I was even able to make some crossing and really very exited to see the results in two years.
Just to say that we should be carefull about the Red Blotch a fungal disease of the lower part of the stem. It begins as a red spot which rotten the whole stem. I had good results by dusting the stem with Captane before planting & make a spray three weeks later.
Some bulbs have longer stems than others with heavy flowers, think to support them with a piece of wood.
