Sue - Thank you! I never thought about Chlorophytum. I have them growing almost wild around my borders and they constantly make prolifs!
I had thought through experience that certain daylily cultivars are more prone to making prolifs than other cultivars. I would love to make a list of cultivars that tend to do that.
Let me start a list of cultivars that are producing prolifs in my garden:
Red Volunteer - 1 prolif
Gleber's Top Cream - 1 prolif
These two are on my top 10 favorites list and I am thrilled to have the opportunity to have more of both of them.
