Oh, very good to know, don't give up next year if nothin' happens. Thanks! Bonus new pics too, awesome! The Lycoris radiata bulbs I found/excavated in the lawn during drought are taking a long time to recover from disturbance as well. Who knows how long they were getting mowed, they were understandably small. Not much happened this year, but in a couple years, when they all get going, it's going to look like "holy cow, that's a lot of red flowers!"
Do you do any kind of leaf cover or other winter regime for that plant, or area they are in? Have they multiplied much?
