Gorgeous! The Bulb River, an arrangement of some 3,500 bulbs of grape hyacinth flanked with thousands of bright yellow daffodils, is located at the Heritage Museums & Gardens in Sandwich, Massachussetts.
If you can't make it there for the full bloom in early May (around Mother's Day), you can take a look at the marvelous photos of the Heritage's gardens over at Flickr - via Atlas Obscura
