I am in Devon but still don't get them all to survive. The best ones are the ones that self seed, they are already used to the climate by winter, they are not really suited to our climate, they love hot dry regions.
They take a three year cycle, here anyway, don't know about anyone else's, so they are a long wait, but well worth it when they do flower. The bees love them.
You do get little ones on the sides, it you leave them, similar to Foxgloves. They make millions of seeds, and they are best left where they fall, they don't transplant well, and as I say, they won't all survive, you can always pull the little plants out next year if you are lucky enough to have them grow,.
