The violet patches on the three petals of the mariposa lily serve as nectar guides to its many pollinators, especially beetles. Photo by Gene Yates.

After the leaves are dead you can cut them back and just leave the bulbs until next year when many will bloom again. High quality bulbs should come back for about 3 years, but they do get weaker year after year. I would like to receive my spring bloomers (like tulips, daffodils, etc) in spring/summer.
The best time to pot up tulips is in early fall, the same as if you were planting them in the ground. Have ready several containers with outside diameters of at least 18 inches and outside heights of at least 15 inches. Using anything smaller reduces the impact of the planting and the viability of the bulbs.
