A few days ago I was surprised to find two Red Spider Lilies (Lycoris radiate) pop up in our backyard. This bulb is native to Japan and used to be a popular planting in the south. They bloom in early Fall for a few days then retreat back to the ground. Having an attractive red lily pop up unexpectedly in Fall is a nice treat. You can purchase spider lily bulbs at local nurseries, but you will have to wait until next year since they need to be planted in the Spring.
