Lycoris are a group that haven't been much mentioned. Lycoris squamigera is an 'old faithful' that I brought from my home garden in Minnesota back in 1964. It grows and prospers here in Eugene. However, the other members I have tried have not been successful. Some have lasted until the next summer but most didn't come back from the first winter. They included L. chinensis, L haywardii, L. longituba, L. sprengeri, L. radiata radiata, L. straminea, L. radiata var. pumila, L. rad. var. pumila X L. sprengeri, L. haywardii X L. chinensis, L longituba X L rosea, and L. chinensis X L. haywardii. The area where these were planted is sandy loam with added organic matter. It was well drained. Also, remember that our winters for the last 4 or 5 have not gone below 22 degrees F...and then only for a night at a time. I don't believe they failed because of the cold weather but rather because of the rain. Louis Mensing Eugene, Oregon
