There’s no guessing about when to visit RoozenGaarde, 15867 Beaver Marsh Road, Mount Vernon, Washington.

This is the largest bulb grower in North America, growing more than 1000 acres of tulip, daffodil, and iris flowers in the Skagit Valley, Washington.

Because they rotate the location of our fields every year — and each field’s exact bloom time depends upon Mother Nature — they have developed a Bloom Map to help Road Trips Gardeners plan their trips. (When your Road Trips Gardener looked, all the daffodil fields were in bloom, but the tulips and iris have yet to flower.)
