Catalogs that specialize in bulbs, like Brent and Becky’s or Van Engelen or Scheepers, should be able to advise you how to stagger your bloom. I recommend for your first outing to make a call to customer service of one or more of these; each catalog uses different wording for the time of bloom (I think Scheepers is closest to the early, mid and late wording; Van Engelen uses parts of the month like April-May or May, and so forth). You can also compare prices; all of these merchants deliver top-quality products. http://brentandbeckysbulbs.com/spring/genus.php?genusid=44
