dbrawner: Are you asking for a general entry for Yucca?
We have a general entry for Yucca filamentosa and separate entries for the different cultivars of Y. filamentosa:
http://garden.org/plants/searc...
Edited to add: I get really confused with some database entries having a "Parent" plant while others have a "General" entry. I'd think cultivation methods would be the same for all of the Y. filamentosa species, so should photo's go here
Adam's Needle (Yucca filamentosa) if we don't know a particular cultivar name?
