Each spring, Skagit Valley in Washington, United States, transforms into a patchwork of colour that celebrates the arrival of bloom season. Throughout April, visitors explore tulip gardens and farmland lined with vibrant rows of flowers, all framed by mountain views. The valley's fertile soils, shaped by centuries of sediment from the Skagit River, make it one of the most productive agricultural regions in the Pacific Northwest. Tulips arrived here in the early twentieth century when farmers realised the cool springs and long daylight hours were ideal for growing bulbs.
