This 1,200-acre estate was established by the Roozen family and Washington Bulb Company in 1985—it's the world's largest family-owned tulip-, daffodil-, and iris-growing business. Fifteen acres of greenhouses are filled with multicolored blossoms, and more than 200,000 bulbs are planted in the show gardens each fall. The Skagit Valley Tulip Festival, held in April, is the main event, when the flowers pop up in neat, brilliant rows across the flat land, attracting thousands
of sightseers. The garden and store are open year-round, and the staff and website are full of helpful advice for both novice and experienced gardeners.
