I've lost plants that have never bloomed, never had pods on them, plants that were new, plants that were in established clumps for several years....
I've never cut scapes on new plants and follow the same thought as Donald - the plant will decide if it can handle blooming. The other thing I do with new plants, if the plant was purchased for crossing and it blooms, I will set pods on them.
Not knowing if a new plant will survive the winter, come up in the spring with a bad case of spring sickness, get eaten by deer, laid on by Cyrus (he's great about watching his big feet, not so good at laying completely in the paths while napping) my thought has always been that I'm not going to waste that first year, better to get seeds when I can. Can't say I've ever lost a plant or even noticed a set back with them treated my way, there are to many other factors that can contribute to a lost plant/set back.
I've got 5 plants struggling to come up right now, 3 northern bred, 2 southern bred, all new to the garden last spring, never bloomed, no pods, easier than normal winter.....
