registered F1 Hybrid List
(sorted by cultivar name)
This list is probably not complete as there are certainly more F1 hybrids between
Hemerocallis Species, but either it is not known in literature or at least
not searchable under its species parents in the AHS checklist.
A list of hybrids with Hemerocallis species (F1 as well as Species x Hybrids)
can be found in the Excelfile (currently filtered on F1 hybrids).
