If you haven’t bought an Easter lily, you should go buy one now. They will be on sale after this weekend, and if you want to you can call it a spring lily. You can enjoy the flowers and fragrance for the next few weeks and then you can plant it outdoors.
Keep the lilies in bright, indirect light until the outdoor nighttime temperatures stay above the 40s. Plant them in a partially sunny site with well-drained soil about 6 inches deep and add a few inches of mulch. Next year, they will bloom in midsummer. They make a nice display when planted in masses, so buy all the ones they have left, even if they are no longer in bloom, and plant them outdoors.
