Erythroniums

I went to a talk about these beauties last night at the local alpine society. Fellow blipper TonyG gave me the good idea to look into the society seeing that I have all these unnamed flowers in my garden! As luck have it we have a big society here on my doorstep with lots of clever people and lots of info. So today I can name my own plant! Let the fun begin! What I know of plants and cultivating them is dangerous, but you have to start somewhere!
