Hello, thanks for using Ask-an-Expert. For tulips, if you want to spread out your bloom time for a longer show, the best bet is to plant tulips from multiple "divisions" by bloom time- early, mid-season, and late tulips. The second (UK) link does a pretty good job of explaining and giving examples of some of the divisions.
Better bulb catalogs will often divide the tulips by bloom time. There is also some good info on the bulb society page.
Keep in mind that the cooler the spring, the longer the tulip flowers will last. If it is an exceptionally warm spring, sometimes the tulips will still bloom more closely together, and not "follow" the bloom times as they are advertised.
I hope you find this information helpful, Nicole
