My hybridizing goal is to grow garden hardy Lilium for my climate. Initially I concentrated on the Trumpet & Aurelian group but now I am mainly interested in tetra Orienpets. I want them to look more like Orientals, for example with colors like L. speciosum.
I do very little culling myself but let the weather do it for me. If you are interested in hybridizing, my advice is to start young as it takes a lot of time. You should grow as many seedlings as possible and only grow from the strongest with traits you want.
