Hi Jennifer, I hope your Great Nursery Excursion of 2016 materializes, as I'm sure it would be a memorable experience.
If you are in Washington in April you may want to attend the Skagit Valley Tulip Festival at Mt. Vernon,WA

And just at the edge of these ..."with 1000+ acres of Skagit Valley tulip, daffodil, and iris fields" near interstate I5 is Skagit Valley Gardens

Or here you can select a state and choose the native plant nurseries along your route that you would like to visit.

Have a safe and wonderful trip.
