Naked ladies, spider lilies, surprise lilies, resurrection lilies are actually Lycoris. There are red (Lycoris radiata), yellow (Lycoris aurea) and pink (Lycoris squamigera). Other names include ninja lily and hurricane lily. But, the best news is that they are easy to grow.
You can buy dormant bulbs from your big box store and plant them now. Bulbs should be planted at a depth where the "neck" is just under the soil line. When planting bulbs in groups, place them about 4 inches apart. Like other bulbs, these like a handful of bone meal per bulb in the planting hole. Well-drained soil and filtered shade are best. Bulbs can be lifted and separated.
Some Lycoris produce fertile seed and some do not. I am wondering if that is where all my Lycoris came from. Surely, I did not buy a bunch of bulbs and plant them willy nilly everywhere. Maybe when transplanting other plants, bulbs were moved as well.
Some professionals suggest making bulb cuttings, but this is not normally practiced by gardeners. Plus, my husband does not allow me to have real sharp objects!
Often these scarlet flowers bloom near cemeteries around the autumnal equinox. The Chinese and Japanese call these flowers "ominous" because it was thought they would guide the dead into the next reincarnation.
