I received the bulbs for the lily in the attached picture at a plant exchange. The person providing the bulbs did not know what the flower was but did know that the bulbs had to be taken out in the fall and replanted in the spring. What is the lily variety and what else do you know about it.
Anoka County Minnesota
There are 100 species of lily and thousands of varieties and cultivars. Also, there are flowers with "lily" in the name that are not in the genus Lilium. Sorry, I cannot identify the cultivar of your flower. Since the bulbs are not hardy, here is a link to the University of Minnesota on storing tender bulbs: https://www.extension.umn.edu/garden/yard-garden/flowers/storing-tender-bulbs/
It appears to be a Peruvian daffodil. Here is a link to the University of Arkansas about the Peruvian daffodil: https://www.uaex.edu/yard-garden/resource-library/plant-week/daffodil-peruvian-6-19-09.aspx.
Please see the University of MN link on storing tender bulbs on my previous answer, which tells what to do for Peruvian daffodil (Hymenocallis narcissifol).
