For a wedding gift to me, my husband bought me the Spring Bride Duet - a combination of Cosmopolitan Darwin Hybrid tulips and Stainless Daffodils. We planted them in the fall of 2014, and they have faithfully come up each year. I thought the daffodils and tulips were a good combination for us in case the deer ate the tulips, the daffodils would still be standing. Also, tulips can fade over time but daffodils multiply. So far, both have come up faithfully, and beautifully, each year, and the deer have left them alone. I would buy Darwin Hybrids again - they have really strong stems and huge flowers! The Cospmopolitans color changes over the time they are up. They come up a pale peach/pink, and then slowly shift to a brighter pinkish/red.
