Itoh Hybrid (Intersectional hybrid). Parentage: [unnamed Lactiflora Group seedling] x [unnamed Lutea Hybrid Group seedling]. Presumed infertile; no seed, no pollen.
Presumed near infertility: "The Itoh Hybrids have for long been known to be highly infertile. Recently, chromosome count findings show they are triploids, reason enough for the observations. Any seeds from Itohs pollination by either triploids or tetraploids are expected to include a share of tetraploids, possibly fertile. Suggestion: pollinate by one or another of their parental Lutea Hybrids or a mix thereof. Expect rare success, requires patience, but persistence is how we got the present generation of Itohs."
