In mid January I potted up some proliferations from a tall growing vigorous NOID, probably old, but definitely magnificent red daylily. It was very hot at the time. Today I found a scape with a prolif in a tub of water that has had gardenia cuttings in it for over a year. My daughter severely pruned the gardenia and I didn't want to waste the cuttings some of which were branches. I have gradually potted them up as they grew huge roots.
The daylily scape was a brown shell. The prolif had long roots so l had to find a big pot for it. I wouldn't recommend this method. However, prolifs from my other cultivars have been small and not made it even given ideal conditions. Maybe when those plants are bigger.
