Daylily that is awesome. I have Alexandra mainly to use in breeding and will start some crosses with it next year. I have added a lot of plants this year for that purpose but did not want to stress them with seed until they were established well. CB is a great plant by the way and should make great crosses with other things too.
Alexandra has not been a real fast increaser but it blooms for a long time and seems to maintain bloom size through the season here.
