Stargazer Lilies

Stargazer Lilies

Please forgive what seems like a really dumb question--I have never grown these or similar flowers before. They are finally blooming! Yay! When/How do I pick them? I know florists often pick the stem just before any of the buds bloom, but I don't know what, if any, voodoo they employ to ensure that said buds do bloom in a vase. If I cut the stem now, I will have some blooms, some buds on each stem. If I wait until the later ones bloom on each stem, the early bloomers will be dead. What to do?
