L anceps spikes can tease you for a long time. Those minimum temperatures should be no problem. What are the daytime temperatures? I have found that my L. anceps need to stay outside even when flowers are open - they last much longer. If I bring the blooming plants into the house, flowers last maybe 1 week. Outside, as much as 3 weeks. They like the cold. I have found that the bloom time can vary from year to year. Some years, the peak is November to early December, other years they can go into February or March. Also different plants have a different "schedule". I have some that just do bloom late. So... patience.
I have also found that the buds need to get wet (rain or hose) - they can have a sticky sap that keeps the flowers from opening. Winter rain helps, if Nature doesn't provide that "overhead" water, then you need to help "her".
